change function with IE

[wilkinnh]

specifically with IE7, the change event doesn't seem to fire till i click the checkbox, and then click off of the checkbox. it was actually 2 clicks instead of just 1. seems like it's only an IE error. the click function works just fine, so i can use that instead and check the this.checked value.

That's because until the checbox loses focus, it hasn't "changed".

Well, even if that is true, that doesn't really solve the problem. It's still inconsistent between browsers. jQuery's appeal is that it should cross-browser and that the developer doesn't have to worry about it.

It's either that IE is right to not lose focus and every other browser is wrong, or the other browsers are right and IE is wrong. Either way, it's an IE bug because it's only occurring in IE. I know it can be fixed because the click function works perfectly. Really, all that needs to be done is to emulate the click function, but also make sure the value has changed.

@wilkinnh If its that simple, why do you write up a patch :)

an example of this is

<div id="navigation">
<ul>
                <li><a href="test.htm">Item
                                </a>
                                <ul>
                                                <li><a href="test.htm">Item</a></li>
                                                <li><a href="test.htm">Item
                                                                </a>

                                                                                                </ul>

</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/

$(document).ready(function() {

});
} else {

$(this).parents("li:first").find("input:checkbox").each(function () {

$(this).attr("checked", false);

});
}
});

 });
</script> 

can be fixed by changing the line

$("input:checkbox").change(function () {

to

 $("input:checkbox").bind("change click keypress", function(){
