Function implementation:

1. Modify the title style. Put the title style of jquery ui. Supports skin resurfacing.

2. Modify the button style and replace it with jqueryui's button button style.

3. Change the background of the modal window to the modal background of jqueryui.

Code: 

//首先要引入jquery，以及ui的包和皮肤的样式如：
<script src="../js/ui/jquery-1.11.0.min.js"></script>
 <script src="../js/ui/jquery-migrate-1.1.0.min.js"></script>
 <script src="../js/ui/minified/jquery.ui.core.min.js"></script>
  <script src="../js/ui/minified/jquery.ui.widget.min.js"></script>
  <script src="../js/ui/minified/jquery.ui.mouse.min.js"></script>
  <script src="../js/ui/minified/jquery.ui.button.min.js"></script>
  <script src="../js/ui/minified/jquery.ui.draggable.min.js"></script>
<link rel="stylesheet" type="text/css" href="../js/ui/themes/humanity/jquery-ui.css"></link>
