Dialog 弹窗
若系统的 alert 窗体无法满足网页的临时视图内容需求，则可以自定义实现与 alert 形式相似的 dialog，并且在 dialog 中可以自定义地使用各种控件，来满足需求。
本节课用到了jquery，所以不熟悉jquery的同学也没事，可以参考实例源码进行学习
在项目中新建dialog.jsp，引入微信的样式库weui.css文件，然后在引入依赖jquery的js库，我在这里呢引入的是网络js库 <script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>
html代码
<br><br> <a href="javascrit:void(0)" class="weui_btn weui_btn_primary" id="dialog1">点击弹窗样式1</a> <a href="javascrit:void(0)" class="weui_btn weui_btn_primary" id="dialog2">点击弹窗样式2</a> <div class="weui_dialog_confirm" style="display: none;"> <div class="weui_mask"></div> <div class="weui_dialog"> <div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div> <div class="weui_dialog_bd">自定义弹窗内容，居左对齐显示，告知需要确认的信息等</div> <div class="weui_dialog_ft"> <a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog default">取消</a> <a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog primary">确定</a> </div> </div> </div> <br><br> <div class="weui_dialog_alert" style="display: none;"> <div class="weui_mask"></div> <div class="weui_dialog"> <div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div> <div class="weui_dialog_bd">弹窗内容，告知当前页面信息等</div> <div class="weui_dialog_ft"> <a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog primary">确定</a> </div> </div> </div>
说明：第二行和第三行用到了weui的按钮，在这里呢，a链接的地址用到了javascript：void(0),意思就是阻止点击按钮跳转。
第六行和第18行是两个弹窗的div块，设置为隐藏状态。
js的实现逻辑是点击按钮1弹出弹窗样式1，点击按钮2，弹出弹窗样式2。实现代码如下：
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery("#dialog1").click(function(){
jQuery(".weui_dialog_confirm").show();
});
jQuery("#dialog2").click(function(){
jQuery(".weui_dialog_alert").show();
});
});
</script>dialog.jsp代码：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>弹窗效果</title>

<body>
<br><br>
<a href="javascrit:void(0)" class="weui_btn weui_btn_primary" id="dialog1">点击弹窗样式1</a>
<a href="javascrit:void(0)" class="weui_btn weui_btn_primary" id="dialog2">点击弹窗样式2</a>
<div class="weui_dialog_confirm" style="display: none;">
<div class="weui_mask"></div>
<div class="weui_dialog">
<div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div>
<div class="weui_dialog_bd">自定义弹窗内容，居左对齐显示，告知需要确认的信息等</div>
<div class="weui_dialog_ft">
<a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog default">取消</a>
<a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog primary">确定</a>
</div>
</div>
</div>
<br><br>
<div class="weui_dialog_alert" style="display: none;">
<div class="weui_mask"></div>
<div class="weui_dialog">
<div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div>
<div class="weui_dialog_bd">弹窗内容，告知当前页面信息等</div>
<div class="weui_dialog_ft">
<a href="<%=basePath%>dialog.jsp" class="weui_btn_dialog primary">确定</a>
</div>
</div>
</div>
</body>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery("#dialog1").click(function(){
jQuery(".weui_dialog_confirm").show();
});
jQuery("#dialog2").click(function(){
jQuery(".weui_dialog_alert").show();
});
});
</script>
</html>效果如下：
