HTML - data Attribute

The HTML data attribute is used to specify the URL for the resource. The data value can be either a URL or the location of a local file of any audio, video, image, etc.

If you have an image, audio, or video file in your system, you can access it and display it on a webpage by specifying its resource address as the value of the data attribute.

It is important to note that the data attribute is only working with the <object> tag, and at least one data and type attribute must be defined within the <object> tag.

Syntax

Following is the syntax of the HTML data attribute −

<object data = "value"></object>

Example

In the following program, we are using the HTML 'data' attribute within the <object> tag to specify the URL of a resource (i.e., audio file).

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML 'data' attribute</title>
   <style>
      object {
         width: 300px;
         height: 150px;
         display: grid;
         place-items: center;
         background-color: aqua;
      }
   </style>
</head>
<body>
   <!--HTML 'data' attribute-->
   <p>Example of the HTML 'data' attribute</p>
   <object data="https://samplelib.com/lib/preview/mp3/sample-6s.mp3" type="audio/mp3"></object>
</body>
</html>

On running the above code, the output window will pop up displaying the audio file on the webpage.

Example

Considering the another scenario, where we are going to use the data attribute with the object tag to specify the URL of the video.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML 'data' attribute</title>
   <style>
      object {
         width: 300px;
         height: 150px;
         display: grid;
         place-items: center;
         background-color: aqua;
      }
   </style>
</head>
<body>
   <!--HTML 'data' attribute-->
   <p>Example of the HTML 'data' attribute</p>
   <object data="https://static.videezy.com/system/resources/previews/000/019/695/original/pointing-pink.mp4" type="video/mp4"></object>
</body>
</html>

When we run the above code, it will generate an output consisting of the video displayed on the webpage.

Example

Let's look at the following example, where we are going to use the data attribute with the object tag to specify image URL.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML 'data' attribute</title>
   <style>
      object {
         width: 300px;
         height: 150px;
         display: grid;
         place-items: center;
         background-color: aqua;
         border: 4px solid black;
      }
   </style>
</head>
<body>
   <!--HTML 'data' attribute-->
   <p>Example of the HTML 'data' attribute</p>
   <h3>Resource image: </h3>
   <object data="https://www.tutorialspoint.com/static/images/simply-easy-learning.png"></object>
</body>
</html>

On running the above code, the output window will pop up displaying the image on the webpage.
