Hello again with another query. I recently came across a jQuery code that allows you to click on an entire table row (tr) to show/hide other rows (specified as .none). I managed to find the code and it works perfectly on JSFiddle. However, when I try to implement it elsewhere, it doesn't work. I suspect that I may have included the wrong jQuery library, but I'm unsure which one is needed for this code to function properly.
You can view the code on JSFiddle here: http://jsfiddle.net/7gwf4uab/
Currently, this is the jQuery library I have included in the header:
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
If anyone could help me figure out what I am doing wrong, I would greatly appreciate it. Thank you in advance!
