Phonegap网络连接 HTML5

Phonegap网络连接判断  官网提供 Network API

cordova 3.4 版本的API  判断网络的连接状态

判断网络是4G  3G  2G  WIFI none 等

 

本文在结尾处 提供Demo下载

 

支持的系统:

  • Amazon Fire OS
  • Android
  • BlackBerry 10
  • iOS
  • Windows Phone 7 and 8
  • Tizen
  • Windows 8

     

    从建立项目说起:

    <1> 在控制台    创建一个phonegap工程  命令如下

     phonegap create my-app
     cd my-app
     phonegap run android
    

    Phonegap网络连接  HTML5

     

    <2> 我们从命令行进入 到工程目录下的  plugins文件夹

    cd my-app
    
    cd plugins

    <3> 现在开始下载插件

    cordova plugin add org.apache.cordova.network-information


    下载完成:

    <4> 添加android 平台工程  (ios把 "android" 替换)

    cordova platform add android

     

    添加完成:

    Phonegap网络连接  HTML5

     

    <5> 编译android工程

    cordova build

     

    编译完成:

    此时将工程导入到 eclipse中

    画圈圈的地方就是  系统生成的代码

     

    将下方语句考到   assets目录下  www/index.html  当中  完全复制过去;

     

    example:

    <!DOCTYPE html>
    
    <html>
        <head>
            <meta charset="utf-8" />
            <meta name="format-detection" content="telephone=no" />
            <!-- WARNING: for iOS 7, remove the width=device-width and height=device-height attributes. See https://issues.apache.org/jira/browse/CB-4323 -->

            <link rel="stylesheet" type="text/css" href="css/index.css" />
            <title>Hello World</title>
        </head>
        <body>
        
     <p><a href="#" style="font-size:30px;" onclick="checkConnection(); return false;">包子的网络连接</a></p>    
    
        <br />
        <br />
        <br />
        <br />
        <div style="font-size:30px;" onclick="aaa();">包子测试</div>
        
        
            <div class="app">
                <h1>Apache Cordova</h1>
                <div id="deviceready" class="blink">
                    <p class="event listening">Connecting to Device</p>
                    <p class="event received">Device is Ready</p>
                </div>
            </div>
            <script type="text/javascript" src="cordova.js"></script>
            <script type="text/javascript" src="js/index.js"></script>
            <script type="text/javascript">
                app.initialize();
            </script>
    
            <script type="text/javascript">
    
            function aaa(){
                alert(111);
            };
    
                //这里是判断网络连接状态的方法
                function checkConnection() {
                    var networkState = navigator.connection.type;
    
                    var states = {};
                    states[Connection.UNKNOWN]  = ‘Unknown connection‘;
                    states[Connection.ETHERNET] = ‘Ethernet connection‘;
                    states[Connection.WIFI]     = ‘WiFi connection‘;
                    states[Connection.CELL_2G]  = ‘Cell 2G connection‘;
                    states[Connection.CELL_3G]  = ‘Cell 3G connection‘;
                    states[Connection.CELL_4G]  = ‘Cell 4G connection‘;
                    states[Connection.CELL]     = ‘Cell generic connection‘;
                    states[Connection.NONE]     = ‘No network connection‘;
    
                    alert(‘Connection type: ‘ + states[networkState]);
                }
    
    
            </script>
    
        </body>
    </html>
    


     

    代码详解:

                    var networkState = navigator.connection.type;
    
                    var states = {};
                    states[Connection.UNKNOWN]  = ‘Unknown connection‘;
                    states[Connection.ETHERNET] = ‘Ethernet connection‘;
                    states[Connection.WIFI]     = ‘WiFi connection‘;
                    states[Connection.CELL_2G]  = ‘Cell 2G connection‘;
                    states[Connection.CELL_3G]  = ‘Cell 3G connection‘;
                    states[Connection.CELL_4G]  = ‘Cell 4G connection‘;
                    states[Connection.CELL]     = ‘Cell generic connection‘;
                    states[Connection.NONE]     = ‘No network connection‘;


    navigator.connection.type  获取当前网络状态

    states数组表示输出的状态  大家可以根据需要自己修改输出的参数

    工程下载    将phonegap的platforms导入到eclipse中  

    如果报错clear一下  查看导的lib包 有没有报错

    如果还有错  那么就是您选用了  google的API   改成最新版的android  API 就好了

    如果导入工程遇到问题 可以查阅我此篇文章
