问题
If I used jquery-1.9.1.min.js
getting JavaScript runtime error: Unable to get property 'opera' of undefined or null reference
from Jquery Isotope v1.5.19
javascript file.
If I use https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
JQuery. It is working properly and goes smooth. I all want to use latest of jQuery.
Any solution for this?

回答1:
If you want to continue using old jQuery APIs, you need to load the jquery-migrate plugin before the jquery.1.9.1.js script.
E.g.
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.1.1.js"></script>
jquery-migrate download and read-me file
** Update:
Try to use Jquery Isotope v1.5.25. It was updated for Jquery 1.9 and doesn't have references to .browser plugin.
