window.event.srcElement doesn’t work for firefox?

I made a web page that works fine with Chrome, but doesn’t with Firefox.
Here’s the code:

function set_email_params(e){
if(!e)
    e=window.Event;   //window.event appeared to be "undefined" so I had to use Event
alert(e.target);        //shows "undefined"
alert(e.target.src);
if(e.target.src.indexOf("unchecked")>-1)
    e.target.src='images/small_radio_checked.png';
else
    e.target.src='images/small_radio_unchecked.png';
}

Here’s how the function is called:

  <img onclick="set_email_params()" src="images/small_radio_unchecked.png" style="float:left;"/>

This code works perfectly on Chrome.
Please help me.

Answer 1

You’re not passing the event object in the handler.

onclick="set_email_params(event)"
   <!---------------------^^^^^--------->

In a standards compliant browser, the event handler will end up looking something like this:

function(event) {
    set_email_params(event);
}

While in older IE it’ll look more like this:

function() {
    set_email_params(event);
}

So either way, the event object will be passed on.
