How can I reliably track mouse enter and leave events?
Various experiments I've carried out indicate that there is no foolproof way of responding to a 'mouseleave' event using jQuery.

<td> tags are stripped from text when injected in MooTools Elements
I'm trying to build some JavaScript in MooTools that fetches table row markup from the server, then adds it to a table. I have an object named htmlAjax that's set as a MooTools Ajax object. The object gets the HTML from the server correctly (tested this in the Firebug console), but when I attempt to add this markup to a new element, the ...
HTML - Which form element caused submit

how do I combine multiple matches (/g) with backreferences in javascript regex match
I'm confused about the array returned by a regex match when using both /g (to get multiple matches) and parentheses (to get backreferences). It's not clear to me how to get the backreferences because the subscript of the match array seems to refer to the multiple matches, not the back references. for instance: string = "@abc @bcd @cde"...

I've been given a table based layout to work on and I need to display some tool tips above some input boxes contained in the table.

AJAX polling of a URL returning JSON doesn't seem to return fresh responses (using jQuery $.ajax() method)
My project requires polling a certain URL for a JSON response, using AJAX. The first AJAX request that I make alerts the server that I want some JSON content, and it begins building and cacheing a response, sending me back { "status" : "pending" } for each subsequent AJAX request until the JSON is ready.
