『伍』 http://weblaaaa.h186.net是官方網站嗎
不是官網。
騰迅的官網是:http://www.qq.com，其它網址全是騙人的。
溫馨提示：
1、騰訊公司客服不會用聊天的形式告知用戶中獎。
2、騰訊公司所有的中獎活動都會在我們的官方主頁上進行公布。
3、對於參加騰訊公司活動中獎的用戶，騰訊公司不會收取任何費用。（如：手續費、運輸費、郵寄費、稅收等），更不會以騰訊公司的名義開通銀行帳戶讓用戶匯款。
『陸』 怎樣在java web中使用fusioncharts
一般是跟jsp配合使用的，這里有個完整的例子供參考：

<%@page import="java.util.*" %>

String userdb = "root"; // MySQL 用戶名
String passdb = ""; // MySQL 密碼
String namedb = "fusioncharts_jspsample"; // MySQL 資料庫名
// 建立資料庫連接
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>

<!-- 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")`

『玖』 JavaWeb：後台判斷是手機登陸還是Pc登陸
兩種方式：第一種用在頁面，第二種用java過濾器
頁面用jq判斷，單獨建立一個js文件，哪個頁面使用，就引入哪個頁面，一般為首頁。引用時，記得先引用jquery
$(function() {
var tag = isMobile(); // true為PC端，false為手機端
if (tag) {
alert("手機");
console.info("手機")
}
});
function isMobile() {
var userAgentInfo = navigator.userAgent;
var mobileAgents = [ "Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod" ];
var mobile_flag = false;
// 根據userAgent判斷是否是手機
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;
// 根據屏幕解析度判斷是否是手機
if (screen_width < 500 && screen_height < 800) {
console.info("check screen")
mobile_flag = true;
}
return mobile_flag;
}
過濾器方式：filter

HttpServletRequest request = (HttpServletRequest)sRequest;
