In a web page using jQUery 1.7.1 and jQUery-UI 1.8.18, if I output $.ui in an alert box when the document is ready, I get [object Object]. However when using Firefox, if I output $.ui in a click event handler, I get 'undefined' as result. With other browsers (latest versions of IE, Chrome and Safari), the result is still [object Object] when clicking on the link.
Here is my HTML Page:
<!doctype html>
<html>
<head>
<title></title>
<script src="Scripts/jquery-1.7.1.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.8.18.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
alert($.ui); // ALERT A
$(document).on("click", ".dialogLink", function () {
alert($.ui); // ALERT B
return false;
});
});
</script>
</head>
<body>
<a href="#" class="dialogLink">Click me!</a>
</body>
</html>
In this post, I reduced to its simplest form another problem I was having described here: $(this).dialog is not a function. I created a new post for the sake of clarity, since the real question is different from the original one now that pin-pointed where the problem resided.
UPDATE:
IF I replace my alerts with simply alert($); I get this result for alert A:
function (selector, context) {
return new jQuery.fn.init(selector, context, rootjQuery);
}
and this one for alert B:
function (a, b) {
return new d.fn.init(a, b, g);
}
This does not make sense to me, although I may not be understanding well enough what $ is...
UPDATE 2:
I can only reproduce this problem using Firefox on OS X. On Firefox running on Windows 7, everything is fine.
