How to update document object value in loop (Javascript)

Question

Hi folks i am a beginer to Java script so appologies if this is a dumb question. I am trying to put the following in a for loop but I can't seem to get it to work.

if (rowID==1) { document.form1.class_titleDis_1.value=class_title; } if (rowID==2) { document.form1.class_titleDis_2.value=class_title;

This is what I tried

var i=1;
for (i=1;i<=2;i++)
{
  document.form1.(class_titleDis_)+i.value=class_title;
}

I would be really grateful for any suggestions. Graham

document.form1.(class_titleDis_)+i.value=class_title;

Should likely be:

document.form1['class_titleDis_'+i].value=class_title;
