one line "hash"

[Jeff Thies]

I have this:

var hash=new Array();
hash['a']='some_value';
hash['b']='some other value';

Whar do you call that in javascript?

I know it's possible to define this in one line, but I've forgotten how.
Something like:

var hash=new Array('a':'some value','b':'some other value') ???

Array. With two new custom properties, called "a" and "b":

alert(hash.a);
alert(hash.b);

You mean:

var hash={a:"some value",b:"some other value");

This is not an Array. This is an Object. And this syntax is called "Object
Initializer".

The previous code is equals to:

var hash=new Object();
hash.a="some value";
hash.b="some other value";

You should be using an object for this application, not an array.

var hash = {a: "some_value", b: "some other value"};

And don't call it a hash. It makes you look like a Perl Boob.
