The jQuery virtualized click event handler.
Part of jQuery Mobile API, vclick exists to abstract mouse and touch events in mobile applications. According to the documentation:
We provide a set of "virtual" mouse events that attempt to abstract away mouse and touch events. This allows the developer to register listeners for the basic mouse events, such as mousedown, mousemove, mouseup, and click, and the plugin will take care of registering the correct listeners behind the scenes to invoke the listener at the fastest possible time for that device.
