When wrapping code inside a function, i pass jQuery at the bottom and the $ sign as a parameter to add it to the functions scope.

(function(window,$,undefined){


}(window, jQuery));

How can i do that with my own Objects?

I load my object in a separate script tag

function MyObj (){
}

So i guessed that all it takes is

(function(window,$,MyObj){

    var myObj = new MyObj();

}(window, jQuery, MyObj));

But MyObj is undefined. I know i could wrap MyObj inside an IFI - but MyObj also needs some json-data that isnt there on page load...

Thanks for your help.

    As long as the separate script tag is BEFORE that IIFE that you've shown, then you shouldn't see that MyObj is undefined. – Adam Sep 01 '14 at 17:55

    ... and "MyObj" must be declared at the global level - if the other script has all its code wrapped in a function like that, then "MyObj" won't be global. – Pointy Sep 01 '14 at 17:57
  • what's the advantage of re-defining a variable that can be reached by the same name from inside the function? – dandavis Sep 01 '14 at 17:59

  • If that were really the case, the function would not be `undefined`. – Pointy Sep 01 '14 at 18:08
  • all good. it works now. sorry for stealing your time. – user3144851 Sep 01 '14 at 18:11
  • if this is supposed to be being done for performance, i doubt today's browsers will benefit. if performance is the only reason to do this, then it's probably not worth doing. – dandavis Sep 01 '14 at 21:28
