这篇文章主要介绍了基于jquery ui的alert,confirm方案(支持换肤)，修改自网友的源码，有需要的小伙伴参考下。

实现功能：

1.修改标题样式。把jquery ui的标题样式放上去。支持换肤。

2.修改按钮样式，换成jqueryui的button按钮样式。

3.将模式化窗口的背景换成了jqueryui的模式化背景。

代码：

//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>
