javascript - 推送通知cordova android中 undefined reference 错误onnotification

Question

使用 Cordova (ionicframework+angularjs) 构建以使用推送通知请求 Android 设备。注册时 successHandler() 被触发并显示('ok')消息结果! 为什么 onNotification() 方法没有被触发？？。

var pushNotification;
    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {

        pushNotification = window.plugins.pushNotification;
        setupNotificationsForandroid();
    }
   //begin setup
    function setupNotificationsForandroid() {
     //  alert("inside setup");
        if ( device.platform == 'android' || device.platform == 'Android' || device.platform == "amazon-fireos" ){

            pushNotification.register(
            successHandler,
            errorHandler,
            {
                "senderID":"856763042820",
                "ecb":"onNotification"
            });
        } else {
            pushNotification.register(
            tokenHandler,
            errorHandler,
            {
                "badge":"true",
                "sound":"true",
                "alert":"true",
                "ecb":"onNotificationAPN"
            });
        }
    }
    function successHandler(result){

        //alert("success"+result);

    }
    function errorHandler(){

        alert("error");
    }
    // Android
    function onNotification(e) {
        //alert("inside onnotification");
        switch( e.event )
        {
        case 'registered':
              if ( e.regid.length > 0 ){
               //set up the server call for storing registraion ids
                 alert(e.regid);
              }

        break;

        case 'message':
                // if this flag is set, this notification happened while we were in the foreground.
            if(e.foreground){
                var soundfile = e.soundname || e.payload.sound;
                var my_media = new Media("android/assets/www/"+ soundfile);
                my_media.play();
            }else{
               // otherwise we were launched because the user touched a notification in the notification tray.
            }


            break;

        case 'error':
               console.log("Error"+e.msg);
               break;

        default:
            console.log("An unknown event");
            return;
      }
    }   

这是我的控制台消息:

09-22 11:38:46.151: I/Web Console(24662): processMessage failed: Stack: ReferenceError: onNotification is not defined
09-22 11:38:46.151: I/Web Console(24662):     at eval (eval at processMessage (file:///android_asset/www/cordova.js:1006:26), <anonymous>:1:1)

基于此 processMessage failed: Stack: ReferenceError: onNotification is not defined 控制台消息我认为是 onNotification() 的问题。请帮忙

Answer 1

onNotification 必须在 window 范围内。

window.onNotification = function(){

}
