基于jquery ui的alert,confirm方案（支持换肤）

前端技术 2023/09/08 JavaScript

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>
<link rel=\"stylesheet\" type=\"text/css\" href=\"../js/ui/themes/humanity/jquery-ui.css\"></link>
