Naming a variable in a function...

This might seem kind of nub, but I cant seem to figure this out. I want to name a variable in a function using a parameter of that function.

For example:

function some_func(number)
{
var testVariable+number = 5;
}

So lets say the "number" parameter was passed the value 2. I would want the variable "testVariable2" to equal 5. Can I do this or do I have to make an array like:

testVariable[number]

Thanks a lot for your help.

I believe that the only way to accomplish this is with an array as you suspected. Any reason why you wanted to avoid using an array?

I don't believe you can implement string substitution in a variable name other than through an array, but since global variables are kept in an array under the window object, it is possible to create a global variable using string substitution through associative array syntax as follows. What it might gain you over a local array, either indexed or associative, is unclear, unless you want to create a global.

benj0323, good morning.

How about giving us a sample of the kind of function you're working on? That way, we could could work out the most relevant approach(es).

Actually, it occurs to me that you could create a local variable using associative array syntax, as the following script demonstrates. You would have to (in the example) always refer to the variable as q.variable_name, but the variable would only have local scope. Again, I'm not sure it isn't more trouble than it's worth.

 window[x]="a";  var q=window.varTest; 
 q[y]="c"; 
 alert(q.d); 
} 
</script> 
</head> 
<body onload="varTest('b','d');"> 
<a href="#" onclick="alert(b);">test global</a><br /> 
<a href="#" onclick="alert(q.d);">test q.local</a><br /> 
</body> 
</html>

Actually I solved the problem on my own. The reason I didnt want to use an array was because using an array didnt work correctly. Here is the code I was using:

var wysiwygEditor = new Array();
wysiwygEditor1 = new FCKeditor( arguments[i] ) ;
wysiwygEditor1.BasePath = 'wysiwyg/' ;
if (! document.all )
wysiwygEditor1.Config['EnableXHTML'] = false ;
wysiwygEditor1.ReplaceTextarea() ;

where "1" was the unique part of the variable. Using an array there didn't work, because there was a bug in the WYSIWYG editor. It's all fixed now and Im using this code:

var wysiwygEditor = new Array();
wysiwygEditor[i] = new FCKeditor( arguments[i] ) ;
wysiwygEditor[i].BasePath = 'wysiwyg/' ;
if (! document.all )
wysiwygEditor[i].Config['EnableXHTML'] = false ;
wysiwygEditor[i].ReplaceTextarea() ;

Thanks a lot for everyone's help.

I need a new FCKeditor.
Does anybody know where I can get one?

You could try the site, [fckeditor.net...] , or SourceForge, [sourceforge.net...]

I believe the production version is 1.6 and version 2 is in its second beta.
