'event' equivalent in Firefox

Question

I am using the following code and it works perfectly fine in Chrome.

function dayBind(xyzValue) {
    if(event.type == 'click')
       alert('Mouse Clicked')
}

Note that there was no 'event' variable passed to the function but still it was available for me in case of chrome. But when I use Firefox I get 'event' undefined. I tried using the following workarounds:

var e=arguments[0] || event;

also:

var e=window.event || event;

But none of them worked for me. Is there any 'event' equivalent in Firefox?

Solution 1

Because IE and Chrome put the event in the global object window, so you can get it. In firefox, you need to let the first parameter be the event.

function dayBind(event, xyzValue) {
    var e=event || window.event;
    if(event.type == 'click')
       alert('Mouse Clicked')
}

If you're setting up the handler with an "onclick" attribute or something (which, since you tagged the question "jQuery", you really should consider not doing), you have to explicitly pass it:

<button type=button onclick='whatever(event)'>Click Me</button>
