JSFiddle: http://jsfiddle.net/QbyUR/

So, I have an empty TD, that I’m trying to remove the white space from.

Normally I’d do this: 

ee.replace(/\s+/, '') == "" // check to see if TD is empty.

the above returns false

but, it wasn’t working so I pasted the contents of my TD to a unicode decoder and got this: 

U+000D <control> character
U+000A <control> character
U+0009 <control> character
U+0009 <control> character
U+0009 <control> character
U+0009 <control> character
U+0020 SPACE character

or 

&#x000d;&#x000a;&#x0009;&#x0009;&#x0009;&#x0009;&#x0020;

The text that I converted is here:

-------


-------

(in between the two lines)

this is what I used: http://software.hixie.ch/utilities/cgi/unicode-decoder/utf8-decoder

I’m 100% certain it’s the control characters that are messing me up. And they are bound to be different across all browsers…

How do I get rid of them? is a regex replace going to be sufficient?

    The real problem here is that you’re using innerText, which is not a property on jQuery objects but rather on DOM elements. Simply use the jQuery function .text() instead:

    var e = $(".td");
var result = e.text().replace(/\s+/, '') == ""; // check to see if TD is empty

alert(result);​

    And everything will work fine. Right now, the string is actually "undefined" because you appended an empty string to a nonexistent property.
