javascript - 检查与 Cordova 的互联网连接是否无法正常工作

Question

我正在使用这个插件来查看我的手机是否有互联网连接: https://github.com/apache/cordova-plugin-network-information

但不工作.. 告诉我这个错误:


D/CordovaLog(3169):文件:///android_asset/www/index.html:第 44 行:未捕获的类型错误:无法读取未定义的属性“连接”


我的功能:

````变种应用= {

//Application Constructor
init: function() {
    this.bindEvents();
},

//Bind Event Listeners
bindEvents: function() {
    document.addEventListener('deviceready', this.onDeviceReady, false);
},

//Event Handle
onDeviceReady: function() {
    //Fast click
    FastClick.attach(document.body);          

    Usuario.verificarOnline();
    DataBase.init();

    alert(App._internet());
},

getUrl: function(){        
    return App.url;
},

//verificar conexao com internet
_internet: function(){
    var networkState = navigator.network.connection.type;

    var states = {};
        states[Connection.UNKNOWN]  = false;
        states[Connection.ETHERNET] = true;
        states[Connection.WIFI]     = true;
        states[Connection.CELL_2G]  = true;
        states[Connection.CELL_3G]  = true;
        states[Connection.CELL_4G]  = true;
        states[Connection.CELL]     = true;
        states[Connection.NONE]     = false;

   return states[networkState];
}

};

Answer 1

要么是你没有安装插件:

cordova plugin add cordova-plugin-network-information

或者这意味着您在调用函数之前没有等待设备准备就绪:

document.addEventListener('deviceready', function()
{
    // Call the function
}
