Question

// Explicit global
$.fn.getRedemptionID = function(){
window.varMy = data.DATA[0].item1;
}

How do you call the above function to get the variable varMy ?

Answer 1

From you previous question, I think you basically want the var to be returned to the calling part.. then you can write as below,

$.fn.getRedemptionID = function(){
   return data.DATA[0].item1;
}

and to call,

var myVar = $(selector).getRedemptionID();
