You can use jQuery migrate for backwards compatibility, and it will show you in the console what needs to be fixed to be up to date with jQuery 1.9+.
From the docs http://blog.jquery.com/2013/02/04/jquery-1-9-1-released/
Please, please, please, use the jQuery Migrate plugin and look at the upgrade guide if you’re just starting your upgrade to jQuery 1.9. The plugin will quickly find and fix any compatibility issues, just look in the browser console. Once you fix the warnings you can remove it. Or, leave the plugin in place until you have the chance to fix your code and plugins to make them 1.9-compatible.
