Awesome! Its genuinely awesome paragraph, I have got
much clear idea regarding from this paragraph.
@Robert Kuropkat:
arguments is a local scope variable available in all functions in Java script see: https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Functions_and_function_scope/arguments
I know this is a rather old post, but I was wondering about the ‘arguments’ argument in lines 68 and 80 (the calls to the super class methods). I assume this was supposed to be arguments passed in when the object is instantiated? Where exactly is the variable ‘arguments’ set? Or was this just intended as a place holder?
Thank you.
I think it comes very handy, when starting new file, not to think what should be in the header or how parent call should look like but concentrate on the main code itself.
This is excellent excellent stuff — should be put in the official ExtJs learning page.
