怎么利用jqueryUI做出提示框？有什么作用？

全年在一个项目中，在弹出窗体上用了alert，效果不是很好。alert是浏览器级别的，一但弹出来，那整个浏览器都被封住，只有你点击了之后才能点击其他页面。有时候用了多标签的框架，感觉很是不方便。所以，萌生用模拟的DIV来代替alert。以下是我做的部分代码，模拟弹出窗体我搜索了很多，最后还是用了JQUERY UI，功能真的很强大。

　　这个类每个WEB页面都要继承的，我把JUQERY的文件的路径也写在里面。

　　WEB页面里，在你添加删除成功需要弹出对话框的时候，只要调用相应的方法就可以了。我这里也就麻烦点，封装了一下，第一次写博客，如有错误，请大家见谅！

　　代码如下。请记得在页面引入 JQUERY 和JQUERY UI 的JS文件还有JQUERY UI 的CSS文件。

protected void LinkButton1_Click(object sender, EventArgs e)
{
MessageBox("小样，你真不厚道！");
//Response.Redirect("Default.aspx");
}

protected void Button1_Click(object sender, EventArgs e)
{
MessageBox("你好，请选择操作。点击跳转将跳转到谷歌主页面！", Request.Url.ToString());
}
