Question

I have two variables:

var cost = new Array();
var maxslot = new Array();

and I set the values like this:

<script>
cost = {"m2mp":"0.05"};
maxslot = {"m2mp":"1000"};
</script>
<script>
cost = {"samp":"0.04"};
maxslot = {"samp":"500"};
</script>

But samp replaces m2mp and if I call alert(cost["m2mp"]), it outputs undefined (if I don’t assign samp, I get the correct output). I tried replacing = with +=, but it did not help (samp and m2mp are both undefined then).

I couldn’t find any solution to “simulate” this:

cost["string"] = string;

Answer 1

Just do this:

<script>
    cost["m2mp"] = "0.05";
    maxslot["m2mp"] = "1000";
    cost["samp"] = "0.04";
    maxslot["samp"] = "500";
</script>

However, the way you want your variables makes them Objects, not Arrays. So you’ll have to replace:

var cost = new Array();
var maxslot = new Array();

With:

var cost = new Object();
var maxslot = new Object();

Or, you could just declare the variables and assign values to it in one line, in a “Object literal”:

var cost    = {'m2mp':'0.05', 'samp': '0.04'}
var maxslot = {'m2mp':'1000', 'samp': '500'}
