在JAVA类中弹出JS对话框,第1张

1:java程序

package org.elb.util

public class JavaScriptDemo_1 {

public static String getJS(){

return "<script language=\"JavaScript\">alert(\"弹出框\")</script>"

}

}

2:JSP页面

<%@ 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>

</head>

<body>

<jsp:useBean id="a" class="org.elb.util.JavaScriptDemo_1"></jsp:useBean>

<%=a.getJS() %>

</body>

</html>

想弹出什么来,就写什么就行了,明白了吗?

用extjs吧，Ext.MessageBox.Warn("修改配置数据会导致系统崩溃，确认继续？",warnModify)

实现的就是你这种效果。

你只需要在你的html中引入extjs相关的代码就可以了。

<script language="javascript">

document.write("<link rel=\"stylesheet\" rel=\"text/css\" href=\"../../../ext/resources/css/ext-all-cdn.css?rnd=" + Math.random() + "\"><\/link>")

document.write("<link rel=\"stylesheet\" rel=\"text/css\" href=\"../style/ext-alarm.css?rnd=" + Math.random() + "\"><\/link>")

document.write("<script type=\"text/javascript\" src=\"../../../ext/adapter/ext/ext-base.js?rnd=" + Math.random() + "\"><\/script>")

document.write("<script type=\"text/javascript\" src=\"../../../ext/ext-all.js?rnd=" + Math.random() + "\"><\/script>")

</script>

extjs的包可以官网上下到。
