I came up with the following code:
// Make the following events bubble in IE
jQuery.each(["submit", "change", "select"], function(i, fix) {
var event = jQuery.event,
special = event.special,
handle = event.handle;
special[fix] = {
setup: function() {
jQuery.event.add(this, "focusin.bubbleIE", function( e
) {
jQuery.event.add(e.data == "submit"?
jQuery(e.target).closest
("form")[0] : e.target, e.data, function( evt ) {
console.log(evt.type);
}, undefined, true);
}, fix);
jQuery.event.add(this, "focusout.bubbleIE", function( e
) {
event.remove(e.data == "submit"?
jQuery(e.target).closest("form")
[0] : e.target, e.data);
}, fix);
},
teardown: function() {
//jQuery.event.remove(this, ".bubbleIE");
}
};
});
And I had to add a "noSpecial" parameter to jQuery.event.add to make
sure that attachEvent is actually called on focusin.
This code work as expected, but as soon as I uncomment the teardown
code or replace my dummy event handler by event.handle , I get "out of
memory" and "stack overflow" errors : (
I'm wondering if it's my installation of IE8 which is buggy or if the
problem is more serious...
The draft of the patch is available as a gist: http://gist.github.com/189976
and I've also built a small test page: http://gist.github.com/189977
If someone else could give it a try that would be great.
