making a variable name variable

How can i use xyz to name a variable?

I am trying something like this:

var xyz = "test";

var (xyz) = "abc";

alert (test);

Would have to display an alert "abc"

You usually aren't supposed to use eval(), but here is one way:


var xyz = "test";
eval("var " + xyz + " = 'abc';");
alert (test);

there's almost always a better option than eval()

is this what you are talking about?

Code:

---

var xyz = "test";

window[xyz] = "abc";

alert (test);

---

(creates "test" as a global, ie, window variable)
