Dynamic variable name 1

[chebbi]

Is it possible to generate dynamic variable names in javascript.
I want to be able to generate variables like v1,v2,v3 etc and the numbers 1,2,3 in the above variable names should come dynamically from a loop like

for (i=0;i<=3;i++)
{
//i need a substitute for the below line
var &quot;v&quot;+i=somevalue;
}

Is this possible to do in javascript? I tried
var eval(&quot;v&quot;+i)=somevalue; but that didnt work.

Use an array, and it'll do what it looks like you're trying without the awkward name manipulation.

Yes, it's possible, but you need to do differently. This might work:

eval("var v"+i+"="+someValue+";");

It's not normally done with js variables though. Like trollacious said, you would normally use an array for that. It's normally done with form variables like this:

var theFld = eval("document.formname.fld"+i);
theFld.value = someValue;

Thanks tracey. I'll try your suggestion. By the way i cannot use arrays as a substitute for this approach due to some design problems. Badrinath Chebbi

There's also a way to achieve the same without doing so much annoying string concatenation:[COLOR=aa0000]

window["v" + i] = somevalue;

[/color]

That's because all global variables are properties of the [COLOR=aa0000]

window

[/color].

And, if you didn't know, it's an alternative way to access properties of objects by name. Check this out:
[COLOR=aa0000]

alert(window["document"]["location"]["href"]);

[/color]
That's practically the same as saying:
[COLOR=aa0000]

alert(window.document.location.href);

[/color]
