Add dynamic properties to JS Object

Is it possible to add properties(params) to a JavaScript object dynamically??

Something like:

var parameters = new Object();
for(var i=1; i<=N; i++)
{
parameters.("myParam_"+i) = SOME_VALUE;
}

??

I've already tried this, and it gives me an error that I was expecting : "identifier expected". Wondering if there's another way of achieving this functionality, and/or some way of manipulating the parameter string so that JS considers it as a identifier.

Any help is appreciated

Thanks!!

Just a shot in the dark - i.e. untested - perhaps:var parameters = new Object();
for(var i=1; i<=N; i++){
var key = "myParam_"+i;
parameters.(key) = SOME_VALUE;
}

You have to use 'eval' IIRC, it looks something like:

eval("parameters.myParam_ " + i +") = SOME_VALUE");

I may not have that exactly right, but hopefully it will put you on the right track.
