A var question

[Lazaroth]

I have two variables "var1" "var2"

See example below:

var var1 = 3;
var var2 = 'var1';

How do I make so var2 = var1 = 3 and not 'var1'?

Take the single quotes off around var1?

This was an simple example just to show what I needed to accompish.
The "real" thing isn't this simple...

[Lazaroth]

In another programming language, to accomplish what I am after is:

exp(var2) , and this would then be 3, but this is javascript and I don't how this is done here.

Are you trying to do this?

var var2 = "\"" + var1 + "\"";

if you write
var2=var1 then var2 gets the value of var1

Exactly what Nightfire said.

Are you trying to do this?

var var2 = "\"" + var1 + "\"";

Not really.


Seriously, don't you understand what I want??

I have 2 variables, one by the name "var1" and one "var2".
The one named "var1" contains a number, 3.
And the one named "var2" contains a text, which is exactly the same as the other variable I want to use, namly "var1".

If I now write alert(var2), the text "var1" is popped up, but I want the text that is in the variable called "var1" popping up.

So instead of "var1" popping up, I want "3" to be popping up.

So, is there a way to convert the text so it thinks that it's the variable called the same thing instead of the name of the variable itself?

alert(window[var2])
