Description
The "$(css, context)" syntax to find elements inside the "context" element doesn't work on jQuery 1.4.4 if the context element's id contains a dot character.
It works on 1.4.2 though!!!
You can use this test page:
<html>
<head>
<script type="text/javascript" src="jquery-1.4.4.min.js"></script>
<script type="text/javascript">
function test()
{
var dotted = document.getElementById("Dotted.Id");
var undotted = document.getElementById("UndottedId");
alert($(".test", dotted).length + " vs " + $(".test", undotted).length);
}
</script>
</head>
<body id="body">
<button type="text" onclick="test()">Press to test</button>
<div id="Dotted.Id" style="border: 2px solid red">
<p class="test">Test</p>
</div>
<div id="UndottedId" style="border: 2px solid black">
<p class="test">Test</p>
</div>
</body>
</html>
When you press the button the "alert" displays "0 vs 1", stating it find 0 elements with class "test" inside "Dotted.Id" but one inside "UndottedId".
If you include "jquery-1.4.2-min.js" instead, it displays "1 vs 1", stating that it finds one result in each DIV, no matter its Id.
Thanks for taking the time to contribute to the jQuery project by writing a bug report and providing a test case!
This is a known issue and already fixed in the jQuery 1.5b1 release. This test case shows that it now works as expected again.
