HTML | DOM onfocusin Event
The HTML DOM onfocusin event occurs when an element is getting focused. The onfocusin is same as onfocus, the only difference is that onfocus event does not bubble.
If you want to find out whether an element or its child gets the focus, you should use the onfocusin event.
The onfocusin event is the opposite of the onfocusout event.
Note: Firefox does not support the onfocusin event but with the help of capturing listener you can find out whether a child of an element gets the focus or not.
Syntax:
In HTML:
<element onfocusin="myScript">
In JavaScript (may not work as expected in Chrome, Safari and Opera 15+):
object.onfocusin = function(){myScript};
In JavaScript, using the addEventListener() method:
object.addEventListener("focusin", myScript);
Example: Using HTML
<!DOCTYPE html> <html> <body> <center> <h1 style="color:green">GeeksforGeeks</h1> <h2>HTML DOM onfocusin Event</h2> Focus: <input type="text" onfocusin="GFGfun(this)"> <script> function GFGfun(foc) { foc.style.background = "yellow"; } </script> </center> </body> </html> |
