Ajax to find the match element to extract the href link

I have the list of 7 blocks where it is showing and the other blocks are hiding. i'm using ajax to extract the element on each block of div class when I press on the enter button of the keyboard on each block, but I can't be able to find the match element in [login to view URL] to find the href url then extract it. I still got undefinded and I still can't find out what the problem is, I tried everything but I can't find out what the problem is. I am looking for someone who has got experience with AJAX, JQUERY, PHP and HTML and would be happy to do for a quick small fix. If you can do for a quick small fix, I will be happy to offer you to do a quick small fix for $10. Here's the website link: [login to view URL] and [login to view URL]
