DropDownList  onchange=""

TextBox onchange=""

CheckBox onclick=""

RadioButton onclick=""

 

JavaScript: Checkbox onChange event is differently processed by IE and FF

Try to click  the following buttons on IE and Firefox.

Using onchange

Using onclick

You have found the difference, right?

Internet Explorer only fires the onchange event when the checkbox loses the focus (onblur) while Firefox fires it immediately.

So you should be very careful to use onchange event if you want to develop cross-browser application. However, it is often overlooked.
