Event target in Firefox

Question

JavaScript

Good afternoon!

There is a function:
function changeHandler(e) {
var targ;
if (!e) var e = window.event;
if (e.target) targ = e.target; else if (e.srcElement) targ = e.srcElement;
alert(targ.type);
}

It hangs on input events: onchange='changeHandler()' onkeyup='changeHandler()'
In IE and Chrome, everything works as intended, an alert pops up with the type of the triggered event. But in Firefox e and, accordingly, targ is always undefined. What could be the reason for this and how to properly get the event object in FF?

Thank you.

Answer 1

onchange='changeHandler(event)' onkeyup='changeHandler(event)' - so try

Answer 3

input: onchange='changeHandler()' onkeyup='changeHandler()' - in this code you do not pass "e" (event), but in "function changeHandler(e) {" you request it.
It should be like this:
input: onchange='changeHandler(e)' onkeyup='changeHandler(e)'
