• javascript
• jquery

• console.log(qsqs, hg); – zerkms Commented Mar 4, 2014 at 0:49
• can you see what's happen after I add your code Blog – abdel Commented Mar 4, 2014 at 0:53
• Yes, I see that you're making wrong assumptions. If you checked console.log for your blog code (or used a debugger) - you could see it as well. – zerkms Commented Mar 4, 2014 at 0:54
• @zerkms Thank you, I forgot to check if the code exist before I executing it. – abdel Commented Mar 4, 2014 at 0:59

1 Answer 1

The problem is that you have another div with the class widget-content and it's causing the jquery selector to run in both.

Example

<div class="widget-content">
    [2][Sport][Two]
</div>
<div class="widget-content">
    .
</div>

Here's the Fiddle updated so you can see the error clearly: http://jsfiddle/679JJ/1/
