Array value rather than content
I have a conditional if/else expression
if(thisLayer.name == “Word1”){
loc = 0;
} else if (thisLayer.name == “Word2”){
loc = 1;
} else loc = 2;As I have 8 of these, times by 8 I want to simplify it.
varArray = [“Word1″,”Word2″,”Word3″,”Word4″,”Word5”];
if I use the expression
varArray[0] …. I get “Word1”
How can I do it the other way, so if I tell it “Word1” it returns 0.

You could set it up as an associative array:
var myArray = [];
myArray[“Word1”] = 0;
myArray[“Word2”] = 1;
myArray[“Word3”] = 2;
myArray[“Word4”] = 3;
myArray[“Word5”] = 4;myArray[“Word3”] // should return 2

Cheers Dan that works brilliantly.
I was trying to use it in conjunction with referencing my Json file…Someone from IT had pointed out that you can title your keys. So they don’t have to be [0] or [1], you can give them values.
So this works better than what I wanted to use it for. I’ve just posted it up as I could not find anything mentioning about labelling Json’s like this. So I think it’s worth sharing.
