Does jQuery live use setInterval?

Question

Is the jQuery live method using setInterval to update the events?

Does this affect performance?

Answer 1

Based on this blog as a resource, it appears that jQuery.live() works by attaching the events to the document. Then, when an event is triggered (such as by a click), the event bubbles up to the document level - at which point it is compared against all the live event handlers. If it matches a live event handler, it fires the event for it.

Answer 2

This blog describes pretty well what's going on behind the scene.

live does not use setinterval but livequery does.
