Code:
$.ajax({
    //....
    success: function() {
    },
On success I want to pop up a fixed height and width window. There is a closed single locates on the window right angle. I did as the following, but it doesn't work.

I add a div which has a class named success-tip. I add some style to it and hide it at first. Then I use the following:

Code:
$.ajax({
    //....
    success: function() {
        success();
        $('.success-tip').show();    
    },
It doesn't pop up. What do I need to do to my code? Thanks in advance.
