looping through controls... help please.

[hopper]

I'm working on a online questionare. The site reads in the questions from a text file so the number of questions and radio button groups is unknown until the asp page runs. I need to validate that the user answered all the questions before the onclick event of the submit button. I am trying to use a javascript function to do this.

The problem I'm running into is how to append the for loop counter variable to the end of a control name.
ie. question1, question2, question3 ...

Here's my code (I know the array style syntax is incorrect, I just put it there to try to show what I was doing.)

function CheckAnswers(iCount)
{
for(int i=1, i<iCount, i++)
{
if (survey.question(i).value != 1)
{
//do something
}
}
}

Any help is greatly appreciated!!!

Thanks in advance,

Scott

Try (untested):

function CheckAnswers(iCount)
{
  var fld;
   for(int i=1, i<iCount, i++)
   { 
      fld = eval(&quot;document.forms[0].survey.question&quot; + i);
      if (fld.value != 1)
      {
         //do something        
      }
   }
}
