In an attempt to follow best practices, we're trying to use the proper JavaScript/jQuery events according to what device you are using. For example, we're building a mobile site that has an tag that will have an onclick or touch event. In the case of an iPhone, we'd like to use the touchstart event. We'd like to test if their device supports touchstart before we bind that handler to the object. If it doesn't, then we will bind onclick instead.

What is the best way to do this?
