Question

Lets say I would like to trigger a custom event, something like:

var foo = 5;

if(foo == 5){
    event(window,'fooIsFive');
}

and then

$(window).live('fooIsfive',function(){
    alert('hey! foo is five!');
});

(Please excuse my poor imagination right now.)

Is that possible? If not, is a similar approach possible?

Answer 1

You can, try this:

$(window).on('fooIsFive', function() { // on = jQ1.7, use bind for other versions
    alert('hey! foo is five!');
});

var foo = 5;
if (foo == 5) {
    $(window).trigger('fooIsFive');
}
