javascript - How do I rewrite this to include a debug statement? -

previously had this.

onsuccess: this.receiverequest.bind(this, callback) 

this returns function receive requests's bound to supplied bind -- same this contains receiverequest method.

so tried rewriting that..

onsuccess   : function () {                         console.log({'xxx: onsuccess': this});            return this.receiverequest.call(this, callback) }.bind(this),         

however doesn't work.. why? idea?

when use .bind(this) on onsuccess function, it's making context of this window or global object - try removing it. should trivial throw debug logic in there, given binding , explicit declaring of context looks may or may not trying achieve more similar this...

// ...  receiverequest: function(callback) {   console.log('received');   callback(); }, onsuccess: function (cb) {                         console.log({'xxx: onsuccess': this});            return this.receiverequest.bind(this, cb) }  // ...  var requestreceivedfunc = myobj.onsuccess(function() {    console.log('my callback');  }); requestreceivedfunc();
