javascript - Ready state is still 1 though I got the Response - 


          togglecompletedcheck : function(e) {             e.stoppropagation();             e.stopimmediatepropagation();             var key = $(e.currenttarget).attr("id");             this.model = todocollection.findwhere({                 key : key             });             this.model.toggle("completed", true);             this.option.collection = todocollection.add(this.model);             var email = this.model.get("email");             var title = this.model.get("title");             var key = this.model.get("key");             var status = this.model.get("status");             var completed = this.model.get("completed");             this.updateuserdata(email, key, title, completed, status);             returnvalue = this.model.save();             console.log(returnvalue);         },

the ready state still 1 in function. variable used window object(returnvalue). when print object again in console(from chrome browser) shows me ready state 4 allows me access responsetext using returnvalue.responsetext. using backbone.js save input backend. returns responsetext saved. in turn, unable access when try says undefined. how responsetext needed in function.

backbone's model.save() method asyncronous. returns value (the javascript xhr object), request not complete @ return time.

to use completed response, pass success or error callbacks save method (docs here):

this.model.save(null, {     success: function(model, response, options) {         // response     },     error: function(model, response, options) {         // response     } });

this can bit of adjustment when used returning responses functions, equivalent functionality possible using callbacks.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
