基於jquery ui的alert,confirm方案(支持換膚)

實現功能:

1.修改標題樣式。把jquery ui的標題樣式放上去。支持換膚。

2.修改按鈕樣式,換成jqueryui的button按鈕樣式。

3.將模式化窗口的背景換成瞭jqueryui的模式化背景。

代碼:

//首先要引入jquery,以及ui的包和皮膚的樣式如:
<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>
