Is there equivalent of onbeforedeactivate event for Firefox etc.?

this works in IE

$('#blah').bind('beforedeactivate', fnBl开发者_如何学Pythonah);

but I can not find equivalent for Firefox and other browsers

beforedeactivate is an IE-specific event handler. The closest you can get are the focusout and blur events.

Usage in JQuery:

function eventHandler(){
    //...
};
$("element").focusout(eventHandler);
$("element").blur(eventHandler);

Links to JQuery implementations:

1. Focusout
2. Blur

You can use

object.addEventListener ("blur", handler, useCapture);

or

object.attachEvent ("onblur", handler);
