Apologies for deliberately cross-posting, but I have an issue where a JavaScript array in SharePoint is showing a different length from HTML (and an incorrect one!)

SO Question

Updated original to add test javascript

Can you make a JS fiddle up of your code please, an example piece of HTML and the JavaScript. jsfiddle.net – Hugh Wood Nov 14 '12 at 8:40
Could you please give us an example on this code? It's hard to help you when we don't have the code – Daniel Ziga Nov 14 '12 at 8:56
not sure the actual code is of any help...SP2010 is returning the SAME javascript array with a different length? The array is identical, the "code" is identical (it's C&P'd) - its just a <script> with an array in there. – BlueChippy Nov 14 '12 at 9:45
It would be a lot of help BlueChippy. From the information provided it isn't possible to ascertain the reason. – Hugh Wood Nov 14 '12 at 10:10
The main reason for this, is that you could be using a variable that is already defined, and you are redefining it. From the code we would be able see that, and correct it possibly by scoping your javascript variables properly. – Hugh Wood Nov 14 '12 at 10:15

I would need to see your javascript code ;) rergardless if its a c&p job! what works for one doesnt mean it would work for another.

Javascript is tempramental in code where sharepoint is not as bad!

As for your code do you have a trailing comma in your code??

this guy explains the issue in more detail :) cba to re-invent the wheel lol

No. IE incorrectly interprets a single trailing comma as an elision and adds one to the length when it shouldn't (ECMA-262 sect. 11.1.4).

hope this helps :)

Thanks, checked for trailing comma but can't see one in either actual or test code...could SP be adding one somehow? – BlueChippy Nov 14 '12 at 11:23
