指南,但它似乎不起作用.
这是我的代码:
我添加了<plugin name =“NetworkStatus”value =“CDVConnection”/>到config.xml.
这个脚本到我的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;似乎导致问题,因为它没有运行以下警报,我也尝试过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
我终于解决了这个问题!! – 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”!!
希望这可以帮助!
