使用Cordova Phonegap 3.3.0检查iOS应用程序上的互联网连接是否正常

我已尝试过关于Cordova文档的this指南,但它似乎无效。

这是我的代码:

我已将<plugin name="NetworkStatus" value="CDVConnection" />添加到config.xml

此脚本发送到我的index.html

    <script type="text/javascript">


        document.addEventListener("deviceready", onDeviceReady, false);

        // device APIs are available
        //
        function onDeviceReady() {
            alert("1"); // runs this alert
            checkConnection();
        }

        function checkConnection() {
            var networkState = Connection.CELL;
            alert("2"); // doesn't run this

            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>

var networkState = Connection.CELL;似乎导致了问题,因为它没有运行以下警报,我也尝试了navigator.connection.type,但同样的事情发生了。

当我在Chrome中运行应用时,控制台会输出以下错误:

Uncaught ReferenceError: Connection is not defined 

有谁知道如何解决这个问题?

干杯

我终于解决了问题!! - 从头开始​​重新开始并执行以下操作:

命令行:

sudo npm install -g cordova
cordova create hello com.example.hello HelloWorld
cd hello
cordova platform add ios
cordova platforms ls //This will list ios
cordova plugin add org.apache.cordova.network-information
cordova build

然后将我的文件(HTML,Javascript等)拖到platforms/ios/www/文件夹中。

在xcode中打开hello.xcodeproj

编辑config.xml并添加以下行:

<feature name="NetworkStatus">
    <param name="ios-package" value="CDVConnection" />
</feature>

然后在我的索引文件中,我使用了JavaScript:

    <script type="text/javascript">
        document.addEventListener("deviceready", onDeviceReady, false);
        // device APIs are available
        function onDeviceReady() {
            if(navigator.network.connection.type == Connection.NONE){
                alert("nocon");
            }else{
                alert("yescon");
            }
        }
    </script>

然后在iPhone / iPad模拟器中运行它,如果有连接则输出“yescon”,如果没有则输出“nocon”!!

希望这有帮助!

检查您是否已将您的Cordova.js文件包含在html中。

<script type="text/javascript" src="cordova.js"></script>

并更改项目的App/Supporting Files/Cordova.plist

<key>Plugins</key>
     <dict>
     <key>NetworkStatus</key>
     <string>CDVConnection</string>
</dict>

答案 2 :(得分:0)

这对我有用:

if(navigator.network.connection.type == Connection.NONE){
//no connection
}else{
//You are connected.
}

虽然我查看了文档,看起来使用这些行有所不同:

var networkState = navigator.network.connection.type;

对于所有细胞数据,

navigator.network.connection.type设置为Connection.CELL_2G

var networkState = Connection.CELL_2G;吗?
