jQuery fade elements from one class to another, on hover

Question

can this be done?

for eg.

.class1{
  background-image:(whatever.jpg)
  color: #fff;
}

.class2{
  background-image:(whatever2.jpg)
  color: #999;
}

can I fade all elements that have class1 to class2 when the mouse is over the element, and back to class1 when mouse is out?

Solution 1

If you give both the same absolute position, using fadeIn() and fadeOut() will have this effect (attached to onmouseover and onmouseout).

Solution 2

If you don't want to use a plugin, you can do the following:

$(".class1").hover(
function () {
    $(this).fadeOut(function () {
        $(this).removeClass("class1").addClass("class2").fadeIn('fast');
    });
},
function () {
    $(this).fadeOut(function () {
        $(this).removeClass("class2").addClass("class1").fadeIn('fast');
    });
});

Solution 3

Have a look at jQuery UI's extension to addClass. It allows a duration parameter to give the possibility of animation.

Here, I think you want to do something like this:

$('.class1').hover(function(){
    $(this).addClass('class2', 800);
}, function(){
    $(this).removeClass('class2', 800);
});

Obviously you'll need to install jQuery UI for this.

Solution 4

I think this plugin is what you are looking for. It allows you to animate between classes. For example:

$('.class1').animateToClass('.class2', 1000);

Solution 5

This is my implementation:

      $(this).fadeOut("fast"); or $(this).hide();
      $(this).removeClass('css1').addClass('css2');
 $(this).fadeIn("slow");

+1 This is also how I understood the question. Note that for color animations you would need either jQuery UI or a plugin like plugins.jquery.com/project/color

can it animate background images? on jquery UI there are only a few css properties listed in animation

@Alexandra So you downloaded the plugin I linked to. Included it just below where you included jQuery and then used the code I showed as an example in conjunction with something like @lonesomeday posted? Because it should work fine, unless you are using jQuery 1.5 which may or may not work with this plugin.

Using jQuery's toggleClass method toggles one class on and off an element. It has nothing to do with two classes and toggling between them.
