Javascript dynamic variable name

Question

I need something like this.

var thing_<?php echo $php_var->n ?> = <?php echo '32' ?>

want to create something like this :

var thing_342 = '32'

What's the question? And why do you need something like that anyway? thing['342'] would usually be saner. — Quentin

It looks like you solved your own problem... Could you elaborate a bit more on what you're going for here? — Brad Christie

You should definitely mention your overall goal here. What you are trying to do is 99% likely to be the wrong way to achieve your goal. — Andrzej Doyle

You need an object, and use it as an associative array/hash/whatever you are used to call it.

var thing = {};
thing[342] = '32';

or

var thing = {342: '32'};

Suppose $php_var->n = 342

var data = <?php echo $php_var->n ?>;
eval("var thing_" + data + "=32;");
alert(thing_342); // output 32

Simple example:

var data = 342;
eval("var thing_" + data + "=32;");
alert(thing_342); // output 32

var container;
var var_name='lolo';
container[var_name]='he he he';
alert(container.lolo);

not exactly what you want, but I guess it is close enough.
