[jquery] Jquery change background color

I was trying out jquery with this example:

 $(document).ready(function(){
      $("button").mouseover(function(){
        $("p#44.test").css("background-color","yellow");
        $("p#44.test").hide(1500);
        $("p#44.test").show(1500);
        $("p#44.test").css("background-color","red");
      });
    });

I expected the following to happen:

1. Color of <p> to turn yellow
2. <p> to slowly fade
3. <p> to slowly show
4. Color of <p> to turn red

But this is what actually happened:

1. <p> turned red
2. <p> slowly hid away
3. <p> slowly showed

Why is that?

This is how it should be:

Code:

$(function(){
  $("button").mouseover(function(){
    var $p = $("#P44");
    $p.stop()
      .css("background-color","yellow")
      .hide(1500, function() {
          $p.css("background-color","red")
            .show(1500);
      });
  });
});

Explanation:

You have to wait for the callback on the animating functions before you switch background color. You should also not use only numeric ID:s, and if you have an ID of your <p> there you shouldn't include a class in your selector.

I also enhanced your code (caching of the jQuery object, chaining, etc.)

Update: As suggested by VKolev the color is now changing when the item is hidden.

try putting a delay on the last color fade.

$("p#44.test").delay(3000).css("background-color","red");

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!
