Requesting dojo.event.connect set up currentTarget in IE

[cris@…]

Dojo "fixes" various event properties, giving standard properties their standard values in IE. Apparently currentTarget is not currently set up, and it would be very nice if it were.

I guess I should thank cris@… for creating a ticket for me. For a detailed explanation of the problem, please look at my original message on dojo-interest.

The crux of the matter is that while IE events don't supply the currentTarget property, you can work around that by referencing this, which is effectively the same as the currentTarget would be:

a_nodes[i].onclick = function (event) {
    ...
    href = this.href;    //works great in IE and Mozilla
    ...
}

But dojo doesn't capture it in this or in currentTarget.

dojo.event.connect(a_nodes[i], "onclick", function (event) {
    ...
    href = event.currentTarget.href;  //works great in Moz but not in IE
    ...
}
dojo.event.connect(a_nodes[i], "onclick", function (event) {
    ...
    href = this.href;  //doesn't work at all
    ...
}

The problem would be solved if dojo would, for IE, save the original this into the fixed-up event as currentTarget.

The best explanation comes from ​http://www.quirksmode.org/js/events_order.html

"But how do you know which HTML element is currently handling the event? target/srcElement don’t give a clue, they always refer to element2 since it is the original source of the event.

"To solve this problem W3C has added the currentTarget property. It contains a reference to the HTML element the event is currently being handled by: exactly what we need. Unfortunately the Microsoft model doesn’t contain a similar property.

"You can also use the this keyword. In the example above it refers to the HTML element the event is handled on, just like currentTarget."

evt.currentTarget should now be correct on IE.

(In [3309] sjmiles) "Added (optional) second parameter (sender) to event.browser.fixEvent to fix missing currentTarget property on IE. Modified five instances of fixEvent invocations to pass 'this' for 'sender'."

Thanks!
