Question

Firstly appologies for the poor title, not sure how to explain this in one line.

I have this Javascript function (stripped down for the purpose of the question)…

function change_col(zone){

    var objects= zone1227.getObjects();

}

I am passing in an integer into the function. Where I have “zone1227”, I want that 1227 to be the integer I pass in.

I’ve tried this;

var zonename = "zone" + zone;

var objects= zonename.getObjects();

but that doesn’t work.

Is this possible? The functions do exist for every possible integer passed in, but I was hoping to keep the code compact rather than a long list of if statements with hardcoded function names.

Answer 1

Since zone1227 is apparently a global variable, it can also be written as window.zone1227 or as window['zone1227']. This means that you can achieve what you describe, by writing this:

function change_col(zone){

    var objects= window['zone' + zone].getObjects();

}

Nonetheless, I agree with Interrobang’s comment above. This is not a good way to accomplish whatever it is that you really want to accomplish. You should not be referring to global variables via strings containing their names.
