[Javascript] variable undefined problem

[hypersdc at cox.net (hypersdc@xxxxxxx)]

I'm having problems with a variable undefined error.

I'm grabbing a set of variables from a file (.js file). I'm cycling through
the variables with a while statement. The problem I'm having is the last
variable is getting an undefined. How can I fix the code so this doesn't
happen.

//Start Code:

var i = 0;
var itemCheck = item0;
while(window.itemCheck)
{

  document.write("<A HREF=" + itemCheck + ">" + itemCheck + "<BR></A>" );

   i++;
x = "item" + i;
itemCheck =eval(x);

if (typeof eval(x) == 'undefined')
    alert('2 Undefined');
else
    alert('2 okay');
itemCheck =eval(x);


}


//End code

//js content
var item0 = "name 1";
var item1 = "name 2";

//end js file content

Thanks in advance
