Simulate CSS hover state using jquery

Question

I would like to know if there is a way that jquery or some other technology can listen for event X and then simulate a different event somewhere else.

The situation I have right now is that I have an image with an image map, and if the user hovers over a mapped area of the image map I want a related part of the content to change states ( in this case activate the hover state ).

Answer 1

$("#element").hover(function(){
  //style some element(s) or do stuff.
});

Keeping in mind all your content is client-side, otherwise make an AJAX request and assign accordingly.
