Hi
I was creating a Menu with MenuItemImage , and every thing was fine with web testing…
but when I tested my project on win32 or Android , this error is shown :
......~PrebuiltRuntimeJs/debugruntime/script/jsb_create_apis.js:243:TypeError: callback.bind is not a function
with a fast look at the source code of the MenuItemImage , I found the mistake I made.
it was not documented clearly , but an example was written at MenuItemSprite which helped me very much.
what I was doing :
var numberItem = new cc.MenuItemImage(normalNumber, selectedNumber, disabledNumber, this.onNumberTouch);
I add the 3 states of the button , and the callback function.
this is ok with web version , but on Native Platforms you need to add the “target”
so the code will be :
var numberItem = new cc.MenuItemImage(normalNumber, selectedNumber, disabledNumber, this.onNumberTouch,this);
that is it …
and it is pretty strange for me because when I add only two states of the MenuItem , no errors occurs when I ignore the “target” , like this :
var noItem = new cc.MenuItemImage(normalNo,selectedNo, this.onNoTouch);
I hope I understand this .
