i've tried to get a return this from a callback, but i always get undefined.
here is the snipped
create: function(currentView, data){
var itsMe = this;
this.thumbsWrapper = this.templates.wrapper().hide();
currentView.append(this.thumbsWrapper);
this.thumbsWrapper.fadeIn("fast", function(){
return itsMe;
});
},
var l = list().create(currentView); //need teh return that i can use chaining
the var l is now undefined, if i use the fadeIn with a callback... if i dont use fadeIn with the callback it returns the obj
anyone an idea why?
What @Felix Kling say is correct, you are not returning anything. If you want to return
itsMe
you will need to do:Which should suffice if you want chaining.
If you want to get a reference to
itsMe
when the fadeout is finished, you will need to pass your own callback:And if you want to have a chaining pattern, which will execute the next function in the chain when fadeout is finished, you will need to pass not a reference to
this
but an object which can queue up commands, implement each command sequentially.You need to return the object in the
create()
function, it is currently not returning anything:
