Jquery animate while hover

I'm looking for a very basic feature: I want to animate a div in it's position while the mouse hovers over a certain area of the window. I've already figured out how and when to fire off the animate function the problem is, that it's limited in its time. I'm looking for a way to move the div relative to it's position while hovering.

Cheers, janik

Edit:

I've created a JDfiddle. Didn't know about that before. jsfiddle.net/Ru2mZ/7 To render out my problem: I want a continuous movement or animation of an object while the mouse is over the button. So a basic animation like $('#id').animate({left: 100},100) wouldn't work since it's limited to a fixed end position and a fixed amount 开发者_开发知识库of time.

        $('#someDiv').bind('mouseenter', function () {
            this.iid = setInterval(function () {
                aniDiv();
            }, 25);
        }).bind('mouseleave', function () {
            this.iid && clearInterval(this.iid);
        });
        function aniDiv() {
            $('#someDiv').animate({ marginLeft: '-=200px' },10);
        };

Here is the documentation of the hover function. http://api.jquery.com/hover/

Basically, you have to

$("#div-id").hover(
  function () {
    //Do whatever you want to any element when the mouse is on the div with id: div-id. If you want to change anything related to the div being hoved, use the $(this) selector.
  },
  function () {
    //Do whatever you want to any element when the mouse was on the div with id: div-id and leaves it. If you want to change anything related to the div being hoved, use the $(this) selector.
  }
);
