Does JS support variable variable names?

[daemon]

Would something like the following php code be possible in JavaScript? If yes how.

$array = array ( 'firstpage', 'secondpage' );
$$array[0] = 'index.html';
echo ( $firstpage );

I am not aware of anything in JavaScript that would allow you to do this. I think you would have to write some extra code to assign a value to another value.

I could be wrong.

of course!

var first = ' mouse ';
var cat = first;

alert(cat);
alert(eval(cat));

That'd do you - right?

* doesn't bother testing this - as per usual *

let me know if it doesn't work.

Good to see someone understands the logic better than most others.

HUH ?

* doesn't understand which way and to who that insinuation / guesture is meant to swing *

You fancy clarifying that a bit more?

oh - and what you're mad at ?

That was meant to be a compliment Flawless, and the fire means REDHOT. Maybe I chose the wrong the smiley, but at the time I thought it was appropreate to point out that I think your JS logic is impressive. I can however now see how that could be misunderstood.

Then again, I suppose you don't generally take compliments either.

he he - that's ok - i get what you mean now.

Thanks for the compliment

All very great, but despite being along the right lines, it doesn't actually demonstrate the real answer to daemon's original question!!!

IMHO the answer is more like this:

<script language="JavaScript">
//although this is hardcoded, the "myvar" bit is just
//a string, and so could be derived from anywhere
var newVarName = "testvar";

//ditto
var newVarValue = "hello world!";

//turn the variable name and value into a variable with
//an assigned value (beware of unescaped quotes when you
//do this for real)
eval(newVarName + "='" + newVarValue + "'");

//we now have a variable called "testvar", so
//let's output the contents!
alert(testvar);
</script>

daemon, does that answer your question?!
