what is log : function() {} in javascript? -


i saw code in quiz , new javascript. although know how function works, still can explain me 3rd line of code. log: function() {} means:

var abc = function() {     return {       log : function() {         console.log(this.val);       }     }; }

it's object property value function. if do:

var x = abc();

you can do:

x.log()

to call function. here's full example:

var abc = function() {      return {        log : function() {          console.log(this.val);        }      };  }    var x = abc();  x.val = "this value";  var y = abc();  y.val = "this y's value";  x.log();  y.log();

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
