function banana() {
alert('banana function called');
}
$('tr').hover(banana, banana);
You can use this code still -- basically what you're doing is setting up a
delegate to call an event handler -- event handlers only accept one
argument, e, which contains the event information including the object from
which the event came. So your banana function will actually be banana(e),
like this:
function banana(e) {
var target;
if(!e) var e = window.event;
if(e.target) {
target = e.target;
} else if(e.srcElement) {
target = e.srcElement;
}
}
>From there you might call another function that takes multiple arguments.
Does that make sense?
