There was a recent question of Stack Overflow looking to disable mouse hover events in jQuery on touch devices. My first thought was why disable them on touch when you could just enable them when touch wasn’t available.
To achieve this you should look at working the other way and instead of disabling mouse over events for touch devices ADD the events for non-touch devices.
Add Modernizr to the project your working on (you’ve probably already got it in there). Once added you can include a test for “touch” by adding it as a class to the HTML element
If the device has touch capabilities then everything will remain as is, however if the device does not have touch then moderizr will covert that from
touch to to
You can then bind your mouse events off the html element having the class of
I’ve put an example of this in the code pen – http://rwd.is/VyRl37
Some other options
This assumes that you’re still loading the jQuery library for all devices and deciding whether to load the mouse over functions based on touch devices. If you’re looking at conditionally loading jQuery itself then you should look at enquire.js to load in jQuery at a specified width.
If you want to keep jQuery for other functions on smaller devices but want to improve performance you could look at using using Zepto.js as a lightweight alternative.
