Possible regression: Finding elements doesn't work if context elements' id contains dot

Reported by: mikioma Owned by:

Blocked by: Blocking:

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:

  <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);
  <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 id="UndottedId" style="border: 2px solid black">
      <p class="test">Test</p>

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.
