‘伍’ http://weblaaaa.h186.net是官方网站吗
不是官网。
腾迅的官网是:http://www.qq.com，其它网址全是骗人的。

‘陆’ 怎样在java web中使用fusioncharts
一般是跟jsp配合使用的，这里有个完整的例子供参考：
<%@page import="javax.swing.JOptionPane"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.sql.*" %>
<%@page import="java.util.*" %>
<%@page import="com.google.gson.*" %>
<%
String hostdb = "localhost:3306"; // MySQl 主机名
String userdb = "root"; // MySQL 用户名
String passdb = ""; // MySQL 密码
String namedb = "fusioncharts_jspsample"; // MySQL 数据库名
// 建立数据库连接
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
Connection con = DriverManager.getConnection("jdbc:mysql://" + hostdb + "/" + namedb , userdb , passdb);
st = con.createStatement();

<title>Creating Charts with Data from a Database - fusioncharts.com</title>
<!-- Step 1: Include the `fusioncharts.js` file. This file is needed to
render the chart. Ensure that the path to this JS file is correct.
Otherwise, it may lead to JavaScript errors.
-->
<script src="fusioncharts.js"></script>
</head>
<body>
<div id="chart"></div>
<!-- Step 2: Include the `FusionCharts.java` file as a package in your
project.
-->
<%@page import="fusioncharts.FusionCharts" %>
<!-- Step 3:Include the package in the file where you want to show
FusionCharts as follows.
Step 4: Create a chart object using the FusionCharts JAVA class
constructor. Syntax for the constructor:
`FusionCharts("type of chart", "unique chart id", "width of chart",
"height of chart", "div id to render the chart",
"data format", "data source")`

‘捌’ WEB为什么进不去呢请大家帮帮忙！~
当前用户权限不够，且配置了超级密码解决方法： 1、获取超级密码，通过超级密码切换到最高权限 2、通过console口配置权限为3的用户
‘玖’ JavaWeb：后台判断是手机登陆还是Pc登陆
两种方式：第一种用在页面，第二种用java过滤器
页面用jq判断，单独建立一个js文件，哪个页面使用，就引入哪个页面，一般为首页。引用时，记得先引用jquery
$(function() {
var tag = isMobile(); // true为PC端，false为手机端
if (tag) {
alert("手机");
console.info("手机")
}
});
function isMobile() {
var userAgentInfo = navigator.userAgent;
var mobileAgents = [ "Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod" ];
var mobile_flag = false;
// 根据userAgent判断是否是手机
for (var v = 0; v < mobileAgents.length; v++) {
if (userAgentInfo.indexOf(mobileAgents[v]) > 0) {
console.info("chenk userAgent")
mobile_flag = true;
break;
}
}
var screen_width = window.screen.width;
var screen_height = window.screen.height;
// 根据屏幕分辨率判断是否是手机
if (screen_width < 500 && screen_height < 800) {
console.info("check screen")
mobile_flag = true;
}
return mobile_flag;
}
过滤器方式：filter
