HTML - selected Attribute
In HTML, to choose element's options from a dropdown menu are utilized using the selected attribute. When it is used, it marks a default option as being already selected when the page loads. The default or preferred option in a list of options is highlighted by this feature, which makes user interactions simpler.
It was used by web developers to improve user experience and make it simpler for users to explore and make decisions on web forms and interfaces by instantly identifying the default selection inside a dropdown.
Syntax
Following is the syntax of the HTML ‘selected’ attribute −
<option selected></option>
Example
In the following example, we are using the HTML 'selected' attribute within the option element to define the value that will be selected on page load.
<!DOCTYPE html> <html lang="en"> <head> <title>HTML 'selected' attribute</title> </head> <body> <!--HTML 'selected' attribute--> <p>Example of the HTML 'selected' attribute</p> <select> <option value="">--Choose your option--</option> <option value="" selected>Hindi</option> <option value="">English</option> <option value="">Telugu</option> </select> </body> </html>
When we run the above code, it will generate an output consisting of the dropdown menu with default value displayed on the webpage.
Example
Considering the another scenario, where we are going to run the scrip using the selected attribute.
<!DOCTYPE html> <html lang="en"> <head> <title>HTML 'selected' attribute</title> </head> <body> <!--HTML 'selected' attribute--> <p>Example of the HTML 'selected' attribute</p> <p>Select any frontend technology that you know: </p> <select> <option value="">--Choose your option--</option> <option value="" id='html' selected>HTML</option> <option value="" id='css'>CSS</option> <option value="" id='javascript'>JavaScript</option> <option value="" id='angular'>Angular</option> <option value="" id='react'>React</option> </select> <button onclick="Add()">Set selected</button> <script> function Add() { document.getElementById('angular').selected = true; } </script> </body> </html>
On executing the above script, the output window will pop up displaying a dropdown menu along with a click button on the webpage.
