  • HTML JavaScript

    A Script is a small program which is used with HTML to make web pages more attractive, dynamic and interactive, such as an alert popup window on mouse click. Currently, the most popular scripting language is JavaScript used for websites.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
    <h1>JavaScript Date and Time example</h1>  
    
    <button type="button"  
    
    onclick="document.getElementById('demo').innerHTML = Date()">  
    
    Click me to display Date and Time.</button>  
    
    <p id="demo"></p>  
    
    </body>  
    
    </html>

    HTML <script> Tag

    The HTML <script> tag is used to specify a client-side script. It may be an internal or external JavaScript which contains scripting statements, hence we can place <script> tag within <body> or <head> section.

    It is mainly used to manipulate images, form validation and change content dynamically. JavaScript uses document.getElementById() method to select an HTML element.

    Example:

    
    
    1. <!DOCTYPE html>  
    2. <html>  
    3. <body>  
    4. <h2>Use JavaScript to Change Text</h2>  
    5. <p id="demo"></p>  
    6. <script>  
    7. document.getElementById("demo").innerHTML = "Hello JavaTpoint";  
    8. </script>  
    9. </body>  
    10. </html>

    HTML events with JavaScript

    An event is something which user does, or browser does such as mouse click or page loading are examples of events, and JavaScript comes in the role if we want something to happen on these events.

    HTML provides event handler attributes which work with JavaScript code and can perform some action on an event.

    Syntax:

    <element event = "JS code">   

    Example:

    <input type="button" value="Click" onclick="alert('Hi, how are you')"> 

    Output:

    Click Event Example

    Click on the button and you csn see a pop-up window with a message

    HTML can have following events such as:

    • Form events: reset, submit, etc.
    • Select events: text field, text area, etc.
    • Focus event: focus, blur, etc.
    • Mouse events: select, mouseup, mousemove, mousedown, click, dblclick, etc.

    Following are the list for Window event attributes:

    Event Event NameHandler NameOccurs when
    onBlurblurWhen form input loses focus
    onClickclickWhen the user clicks on a form element or a link
    onSubmitsubmitWhen user submits a form to the server.
    onLoadloadWhen page loads in a browser.
    onFocusfocusWhen user focuses on an input field.
    onSelectselectWhen user selects the form input filed.

    Note: You will learn more about JavaScript Events in our JavaScript tutorial.

    Let’s see what JavaScript can do:

    1) JavaScript can change HTML content.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
    <p>JavaScript can change the content of an HTML element:</p>  
    
    <button type="button" onclick="myFunction()">Click Me!</button>  
    
    <p id="demo"></p>  
    
    <script>  
    
    function myFunction() {   
    
        document.getElementById("demo").innerHTML = "Hello JavaTpoint!";  
    
    }  
    
    </script>  
    
    </body>  
    
    </html>

    2) JavaScript can change HTML style

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
    <p id="demo">JavaScript can change the style of an HTML element.</p>  
    
    <script>  
    
    function myFunction() {  
    
        document.getElementById("demo").style.fontSize = "25px";   
    
        document.getElementById("demo").style.color = "brown";  
    
        document.getElementById("demo").style.backgroundColor = "lightgreen";         
    
    }  
    
    </script>  
    
    <button type="button" onclick="myFunction()">Click Me!</button>  
    
    </body>  
    
    </html>

    3) JavaScript can change HTML attributes.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
    <script>  
    
    function light(sw) {  
    
        var pic;  
    
        if (sw == 0) {  
    
            pic = "pic_lightoff.png"  
    
        } else {  
    
            pic = "pic_lighton.png"  
    
        }  
    
        document.getElementById('myImage').src = pic;  
    
    }  
    
    </script>  
    
    <img id="myImage" src="pic_lightoff.png" width="100" height="180">  
    
    <p>  
    
    <button type="button" onclick="light(1)">Light On</button>  
    
    <button type="button" onclick="light(0)">Light Off</button>  
    
    </p>  
    
    </body>  
    
    </html>

    Use External Script

    Suppose, you have various HTML files which should have same script, then we can put our JavaScript code in separate file and can call in HTML file. Save JavaScript external files using .js extension.

    Note: Do not add <script> tag in the external file, and provide the complete path where you have put the JS file.

    Syntax:

    1. <script type=”text/javascript” src=”URL “></script>  

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
       <head>  
    
        <script type="text/javascript" src="external.js"></script>  
    
        </head>  
    
         <body>  
    
          <h2>External JavaScript Example</h2>  
    
           <form onsubmit="fun()">  
    
             <label>Enter your name:</label><br>  
    
          <input type="text" name="uname" id="frm1"><br>  
    
           <label>Enter your Email-address:</label><br>    
    
          <input type="email" name="email"><br>  
    
          <input type="submit">  
    
      </form>  
    
     </body>  
    
     </html>

    JavaScript code:

    function fun() {  
    
           var x = document.getElementById("frm1").value;  
    
            alert("Hi"+" "+x+ "you have successfully submitted the details");  
    
        }

    Output:

    HTML JavaScript

    HTML <noscript> Tag

    HTML <noscript> tag is used to write disabled script in the browser. The text written within <noscript></noscript> tag is not displayed on the browser.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
    <p id="demo"></p>  
    
    <script>  
    
    document.getElementById("demo").innerHTML = "Hello JavaScript!";  
    
    </script>  
    
    <noscript>This text is not visible in the browser.</noscript>  
    
    </body>  
    
    </html>
  • HTML iframes

    HTML Iframe is used to display a nested webpage (a webpage within a webpage). The HTML <iframe> tag defines an inline frame, hence it is also called as an Inline frame.

    An HTML iframe embeds another document within the current HTML document in the rectangular region.

    The webpage content and iframe contents can interact with each other using JavaScript.

    Iframe Syntax

    An HTML iframe is defined with the <iframe> tag:

    <iframe src="URL"></iframe>  

    Here, “src” attribute specifies the web address (URL) of the inline frame page.

    Set Width and Height of iframe

    You can set the width and height of iframe by using “width” and “height” attributes. By default, the attributes values are specified in pixels but you can also set them in percent. i.e. 50%, 60% etc.

    Example: (Pixels)

    <!DOCTYPE html>    
    
    <html>    
    
    <body>    
    
    <h2>HTML Iframes example</h2>    
    
    <p>Use the height and width attributes to specify the size of the iframe:</p>    
    
    <iframe src="https://www.javatpoint.com/" height="300" width="400"></iframe>    
    
    </body>    
    
    </html>

    Example: (Percentage)

    <!DOCTYPE html>    
    
    <html>    
    
    <body>    
    
    <h2>HTML Iframes</h2>    
    
    <p>You can use the height and width attributes to specify the size of the iframe:</p>    
    
    <iframe src="https://www.javatpoint.com/" height="50%" width="70%"></iframe>    
    
    </body>    
    
    </html>

    You can also use CSS to set the height and width of the iframe.

    Example:

    
    
    1. <!DOCTYPE html>    
    2. <html>    
    3. <body>    
    4. <h2>HTML Iframes</h2>    
    5. <p>Use the CSS height and width properties to specify the size of the iframe:</p>    
    6. <iframe src="https://www.javatpoint.com/" style="height:300px;width:400px"></iframe>    
    7. </body>    
    8. </html> 

    Remove the border of iframe

    By default, an iframe contains a border around it. You can remove the border by using <style> attribute and CSS border property.

    Example:

    
    
    1. <!DOCTYPE html>    
    2. <html>    
    3. <body>    
    4. <h2>Remove the Iframe Border</h2>    
    5. <p>This iframe example doesn't have any border</p>     
    6. <iframe src="https://www.javatpoint.com/" style="border:none;"></iframe>    
    7. </body>    
    8. </html> 

    You can also change the size, color, style of the iframe’s border.

    Example:

    <!DOCTYPE html>    
    
    <html>    
    
    <body>    
    
    <h2>Custom Iframe Border</h2>    
    
    <iframe src="https://www.javatpoint.com/" style="border:2px solid tomato;"></iframe>    
    
    </body>    
    
    </html>

    Iframe Target for a link

    You can set a target frame for a link by using iframe. Your specified target attribute of the link must refer to the name attribute of the iframe.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <body>  
    
      
    
    <h2>Iframe - Target for a Link</h2>  
    
    <iframe height="300px" width="100%" src="new.html" name="iframe_a"></iframe>  
    
    <p><a href="https://www.javatpoint.com" target="iframe_a">JavaTpoint.com</a></p>  
    
    <p>The name of iframe and link target must have same value else link will not open as a frame. </p>  
    
      
    
    </body>  
    
    </html>
    HTML iframes

    new.hmtl output code:

    <!DOCTYPE html> <html> <head> <style> p{ font-size: 50px; color: red;} </style> </head> <body style="background-color: #c7f15e;"> <p>This is a link below the ifarme click on link to open new iframe. </p> </body> </html>

    Embed YouTube video using iframe

    You can also add a YouTube video on your webpage using the <iframe> tag. The attached video will be played at your webpage and you can also set height, width, autoplay, and many more properties for the video.

    Following are some steps to add YouTube video on your webpage:

    • Goto YouTube video which you want to embed.
    • Click on SHARE ➦ under the video.
    • Click on Embed <> option.
    • Copy HTML code.
    • Paste the code in your HTML file
    • Change height, width, and other properties (as per requirement).

    Example:

    1. <iframe width=”550″ height=”315″ src=”https://www.youtube.com/embed/JHq3pL4cdy4″ frameborder=”0″ allow=”accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture” allowfullscreen style=”padding:20px;”></iframe>  
    2.         <iframe width=”550″ height=”315″ src=”https://www.youtube.com/embed/O5hShUO6wxs” frameborder=”0″ allow=”accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture” style=”padding:20px;”>></iframe> 

    Output:

    HTML iframes

    Attributes of <iframe>

    Attribute nameValueDescription
    allowfullscreenIf true then that frame can be opened in full screen.
    heightPixelsIt defines the height of the embedded iframe, and the default height is 150 px.
    nametextIt gives the name to the iframe. The name attribute is important if you want to create a link in one frame.
    frameborder1 or 0It defines whether iframe should have a border or not. (Not supported in HTML5).
    WidthPixelsIt defines the width of embedded frame, and default width is 300 px.
    srcURLThe src attribute is used to give the path name or file name which content to be loaded into iframe.
    sandbox
    This attribute is used to apply extra restrictions for the content of the frame
    allow-formsIt allows submission of the form if this keyword is not used then form submission is blocked.
    allow-popupsIt will enable popups, and if not applied then no popup will open.
    allow-scriptsIt will enable the script to run.
    allow-same-originIf this keyword is used then the embedded resource will be treated as downloaded from the same source.
    srcdocThe srcdoc attribute is used to show the HTML content in the inline iframe. It overrides the src attribute (if a browser supports).
    scrolling
    It indicates that browser should provide a scroll bar for the iframe or not. (Not supported in HTML5)
    autoScrollbar only shows if the content of iframe is larger than its dimensions.
    yesAlways shows scroll bar for the iframe.
    noNever shows scrollbar for the iframe.
  • HTML Id Attribute

    The id attribute is used to specify the unique ID for an element of the HTML document. It allocates the unique identifier which is used by the CSS and the JavaScript for performing certain tasks.

    Note: In the Cascading Style sheet (CSS), we can easily select an element with the specific id by using the # symbol followed by id.

    Note: JavaScript can access an element with the given ID by using the getElementById() method.

    Syntax

    <tag id="value">  

    Example 1: The following example describes how to use the id attribute in CSS document:

    <!DOCTYPE html>  
    
    <html>  
    
    <head>  
    
    <title>  
    
    Example of Id attribute in CSS  
    
    </title>  
    
    <style>  
    
    #Cars {  
    
    padding: 40px;  
    
    background-color: lightblue;  
    
    color: black;      
    
    text-align: center;  
    
    }   
    
      
    
    #Bikes  
    
    {  
    
    padding: 50px;  
    
    background-color: lightGreen;  
    
    text-align: center;  
    
    }  
    
    </style>  
    
    </head>  
    
    <body>  
    
    <p> Use CSS to style an element with the id: </p>  
    
    <h1 id="Cars"> Cars </h1>  
    
    <h1 id="Bikes"> Bikes </h1>  
    
    </body>  
    
    </html>

    Output:

    HTML Id Attribute

    Example 2: The following example describes how to use the ID attribute in JavaScript.

    <!DOCTYPE html>  
    
    <html>   
    
    <head>   
    
    <title> Date Attribute </title>   
    
    <script>   
    
    function viewdate() {   
    
    var x = document.getElementById("dob").value;   
    
    document.getElementById("demo").innerHTML = x;   
    
    </script>   
    
    </head>   
    
    <body>   
    
    Employee Name: <input type="text" placeholder="Your Good name"/>   
    
    <br>  
    
    <br>  
    
    Date of Joining:   
    
    <input type="date" id="dob">  
    
    <br>   
    
    <button onclick="viewdate()"> Submit   
    
    </button>   
    
    <br>  
    
    <h2 id="demo"> </h2>   
    
    </body>   
    
    </html>

    Output:

    HTML Id Attribute
  • HTML style using CSS

    Let’s suppose we have created our web page using a simple HTML code, and we want something which can present our page in a correct format, and visibly attractive. So to do this, we can style our web page with CSS (Cascading Stylesheet) properties.

    CSS is used to apply the style in the web page which is made up of HTML elements. It describes the look of the webpage.

    CSS provides various style properties such as background color, padding, margin, border-color, and many more, to style a webpage.

    Each property in CSS has a name-value pair, and each property is separated by a semicolon (;).

    Note: In this chapter, we have given a small overview of CSS. You will learn everything in depth about CSS in our CSS tutorial.

    Example:

    <body style="text-align: center;">  
    
          <h2 style="color: red;">Welcome to javaTpoint</h2>  
    
          <p style="color: blue; font-size: 25px; font-style: italic ;">This is a great website to learn technologies in very simple way. </p>  
    
    </body>

    In the above example, we have used a style attribute to provide some styling format to our code.

    Output:

    Welcome to javaTpoint

    This is a great website to learn technologies in very simple way.


    Three ways to apply CSS

    To use CSS with HTML document, there are three ways:

    • Inline CSS: Define CSS properties using style attribute in the HTML elements.
    • Internal or Embedded CSS: Define CSS using <style> tag in <head> section.
    • External CSS: Define all CSS property in a separate .css file, and then include the file with HTML file using tag in section.

    Inline CSS:

    Inline CSS is used to apply CSS in a single element. It can apply style uniquely in each element.

    To apply inline CSS, you need to use style attribute within HTML element. We can use as many properties as we want, but each property should be separated by a semicolon (;).

    Example:

    <h3 style="color: red;  
    
                font-style: italic;  
    
                text-align: center;  
    
                font-size: 50px;  
    
                padding-top: 25px;">Learning HTML using Inline CSS</h3>

    Output:

    Learning HTML using Inline CSS


    Internal CSS:

    An Internal stylesheets contains the CSS properties for a webpage in <head> section of HTML document. To use Internal CSS, we can use class and id attributes.

    We can use internal CSS to apply a style for a single HTML page.

    Example:

    
    
    1. <!DOCTYPE html>  
    2. <html>  
    3. <head>  
    4.                   <style>  
    5.       /*Internal CSS using element name*/  
    6.             body{background-color:lavender;  
    7.              text-align: center;}  
    8.              h2{font-style: italic;  
    9.               font-size: 30px;  
    10.               color: #f08080;}  
    11.             p{font-size: 20px;}  
    12.         /*Internal CSS using class name*/  
    13.             .blue{color: blue;}  
    14.             .red{color: red;}  
    15.             .green{color: green;}  
    16.       </style>  
    17.     </head>  
    18.   <body>  
    19.    <h2>Learning HTML with internal CSS</h2>  
    20.     <p class="blue">This is a blue color paragraph</p>  
    21.     <p class="red">This is a red color paragraph</p>  
    22.     <p class="green">This is a green color paragraph</p>  
    23.   </body>  
    24. </html>

    Note: In the above example, we have used a class attribute which you will learn in the next chapter.


    External CSS:

    An external CSS contains a separate CSS file which only contains style code using the class name, id name, tag name, etc. We can use this CSS file in any HTML file by including it in HTML file using <link> tag.

    If we have multiple HTML pages for an application and which use similar CSS, then we can use external CSS.

    There are two files need to create to apply external CSS

    • First, create the HTML file
    • Create a CSS file and save it using the .css extension (This file only will only contain the styling code.)
    • Link the CSS file in your HTML file using tag in header section of HTML document.

    Example:

    <!DOCTYPE html>  
    
    <html>  
    
    <head>  
    
        <link rel="stylesheet" type="text/css" href="style.css">  
    
        </head>  
    
      <body>  
    
       <h2>Learning HTML with External CSS</h2>  
    
        <p class="blue">This is a blue color paragraph</p>  
    
        <p class="red">This is a red color paragraph</p>  
    
        <p class="green">This is a green color paragraph</p>  
    
      </body>  
    
    </html>

    CSS file:

    body{
    background-color:lavender;
    text-align: center;
    }
    h2{
    font-style: italic;
    size: 30px;
    color: #f08080;
    }
    p{
    font-size: 20px;
    }
    .blue{
    color: blue;
    }
    .red{
    color: red;
    }
    .green{
    color: green;
    }

    Commonly used CSS properties:

    HTML <form> element attributes

    In HTML there are various attributes available for <form> element which are given below:

    HTML action attribute

    The action attribute of <form> element defines the process to be performed on form when form is submitted, or it is a URI to process the form information.

    The action attribute value defines the web page where information proceed. It can be .php, .jsp, .asp, etc. or any URL where you want to process your form.

    Note: If action attribute value is blank then form will be processed to the same page.

    Example:

    <form action="action.html" method="post">  
    
    <label>User Name:</label><br>  
    
    <input type="text" name="name"><br><br>

    HTML method attribute

    The method attribute defines the HTTP method which browser used to submit the form. The possible values of method attribute can be:

    • post: We can use the post value of method attribute when we want to process the sensitive data as it does not display the submitted data in URL.

    Example:

    <form action="action.html" method="post">  
    • get: The get value of method attribute is default value while submitting the form. But this is not secure as it displays data in URL after submitting the form.

    AD

    Example:

    1. <form action=”action.html” method=”get”>  

    When submitting the data, it will display the entered data in the form of:

    1. file:///D:/HTML/action.html?name=JavaTPoint&pass=123  

    HTML target attribute

    The target attribute defines where to open the response after submitting the form. The following are the keywords used with the target attribute.

    • _self: If we use _self as an attribute value, then the response will display in current page only.

    Example:

    1. <form action=”action.html” method=”get” target=”_self”>  
    • _blank: If we use _blank as an attribute it will load the response in a new page.

    Example:

    <form action="action.html" method="get" target="_blank">  

    HTML autocomplete attribute

    The HTML autocomplete attribute is a newly added attribute of HTML5 which enables an input field to complete automatically. It can have two values “on” and “off” which enables autocomplete either ON or OFF. The default value of autocomplete attribute is “on”.

    Example:

    1. <form action=”action.html” method=”post” enctype=”application/x-www-form-urlencoded” >  
    • multipart/form-data: It does not encode any character. It is used when our form contains file-upload controls.

    Example:

    1. <form action=”action.html” method=”post” enctype=”multipart/form-data”>  
    • text/plain (HTML5): In this encoding type only space are encoded into + symbol and no any other special character encoded.

  • HTML Ordered List | HTML Numbered List

    HTML Ordered List or Numbered List displays elements in numbered format. The HTML ol tag is used for ordered list. We can use ordered list to represent items either in numerical order format or alphabetical order format, or any format where an order is emphasized. There can be different types of numbered list:

    • Numeric Number (1, 2, 3)
    • Capital Roman Number (I II III)
    • Small Romal Number (i ii iii)
    • Capital Alphabet (A B C)
    • Small Alphabet (a b c)

    To represent different ordered lists, there are 5 types of attributes in <ol> tag.

    TypeDescription
    Type “1”This is the default type. In this type, the list items are numbered with numbers.
    Type “I”In this type, the list items are numbered with upper case roman numbers.
    Type “i”In this type, the list items are numbered with lower case roman numbers.
    Type “A”In this type, the list items are numbered with upper case letters.
    Type “a”In this type, the list items are numbered with lower case letters.

    HTML Ordered List Example

    Let’s see the example of HTML ordered list that displays 4 topics in numbered list. Here we are not defining type=”1″ because it is the default type.
