The HTML DOM Input Checkbox autofocus property returns and modify the value of autofocus attribute of an input HTML element with type=”checkbox”.
Syntax
Following is the syntax −
1. Returning autofocus
object.autofocus
2. Modifying autofocus
object.autofocus = true|false
Example
Let us see an example of autofocus property −
<!DOCTYPE html> <html> <head> <title<HTML DOM autofocus property</title< <style> body{ text-align:center; } p{ font-size:1.5rem; color:#ff8741; } input{ width:30px; height:30px; outline:2px solid #db133a; } button{ background-color:#db133a; color:#fff; padding:8px; border:none; width:120px; margin:0.5rem; border-radius:50px; outline:none; } </style> </head> <body> <h1>autofocus Property Example</h1> <p>Do you need help?</p> <input type="checkbox" autofocus> <br> <button onclick="yes()">Yes</button> <button onclick="no()">No</button> <script> function yes() { document.querySelector("input").checked = true; } function no() { document.querySelector("input").checked = false; } </script> </body> </html>
Output
This will produce the following output −
Click on “Yes/No” button to check and uncheck the checkbox but as you can see the checkbox already gets autofocus when page load with red outline.
