I am trying to use some simple jQuery to change the background image on a CSS class of a input with a class.

I have the code below in the box. I have seen the 'background-image' as that and 'backgroundImage' both showed no errors, but does not change my image.

Any ideas?

Thanks,

Ryan
jQuery("input.submit").hover(
		  function () {
		  $(this).css('background-image','url(../images/submit-on.png)');
		   console.log("over");
		  }, 
		  function () {
		    $(this).css('background-image','url(../images/submit-off.png)');
		  }
		);

Your button submit is including the class=".submit"?
what is the size of the button and the image?

This should work unless you have problems with the image size:

  <input class="submit" type="submit" value="click here" />

you switch syntax in your code from jQuery to dollar sign.  Pick one and stick with.  You can do this:

(NOTE: I save the button in a variable for better performance)
(function($) {
    var $btnSubmit = $('input.submit')
    $btnSubmit.hover(function() {
        $btnSubmit.css('background-image','url(../images/submit-on.png)');
    }, function() {
        $btnSubmit.css('background-image','url(../images/submit-off.png)');
    });
}(jQuery));

Looking back at my code, it should be noted that my "button caching" (saving the button in a variable) works only if you have ONE button with that class name on the page.

Basically, if you use my code above and have multiple submit buttons on the page with class="submit", then rolling over ONE of the buttons will change the background on ALL of the submit buttons on the page... which would look really crazy.

Using my last method, the performance gain is negligible... meaning you should just stick with this:

(apologies)
(function($) {
    $('input.submit').hover(function() {
        $(this).css('background-image','url(../images/submit-on.png)');
    }, function() {
        $(this).css('background-image','url(../images/submit-off.png)');
    });
}(jQuery));
