Dynamic variable name in Javascript?

Hello everyone,
after some searching, I managed to figure it out!
All you have to do is use window[variable_name] or variable_name can obviously be a variable.
And there you go!

What do you call a dynamic variable?

THANK YOU VERY MUCH!!

Not a dynamic variable, but a dynamic variable name.

Basically, I would like the name of my variable to change in order to reach different objects depending on the case.

Example:

$document.Formulaire.Champ_'Variable part of the name'.value

To illustrate the case:

I have a function that can be reached from several places.
I would like to pass a parameter that is the 'variable part of the name', knowing that:

- I have several variable names within the function that need to be dynamic
- I would like to avoid passing X parameters, one for each variable I need to reach.

Hoping this helps you understand my problem ;)

So you need to mix PHP with JS
what I can suggest is to put

$variable = your_JS_variable;

Just like samsam: Perfect!

And for those who want to simplify the formula:

function Test(Element)
{
return document.Formulaire.eval('Prix_'+Element).value;
}

THANK YOU for your solution Tiret,

I haven't tested it yet, but if it works, it's well thought out.
Actually, the principle you describe in your post is that of pointers
used in several languages (C or Java, for example).
Indeed, the variable Price contains the "address" of the variable Price_Wood which
itself contains the value 5000 after assignment. Correct me if I'm wrong. Good luck.

Price ---> Price_Wood = 5000

Man.

Well, you're a champ! Your example illustrates perfectly what I needed...

That's half a day saved! You named your problem well; it's exactly the terms I typed thinking about this issue... thanks a thousand times.

Well done!
I really like dynamic variable names in PHP and I'm quite perplexed about applying it in JavaScript...
Thank you very much!

THANK YOU, THANK YOU, THANK YOU !
