Question

I want to run a loop that auto increase the function name by 1. For easier to understand:

My currently code:

 for(var i = 1; i <= 2; i++) {
                var fn = 'this.getExterior',
                    el = (fn + i + '()').getInnerItems();
}

I want to increase the function name and retrieve something like this.getExterior1 , this.getExterior2. The above code give me an object not a function. Can someone give me a solution how to achieve it. Thank you very much in advance!

Answer 1

You can’t really use strings as code (eval can but it’s not necessary here). You can use the [] syntax:

el = this["getExterior" + i]().getInnerItems();

(Also, function is a keyword; you cannot use it as a variable name.)
