Can you have variables inside your

[MartDawg]

Can you have variables inside your javascript objects. For example, would the following code work?

Let's say I have a group of checkboxes named, check1, check2, check3, ect. Up to 20...

Can I do the following...

for(var i=0; i<=20; i++){
if (window.document.form.check&quot;+i+&quot;.checked == true){
Dome some stuff
}
}

Can I put a variable to call an object like that?

I basically need a way to loop through the checkboxes and if they are checked, than I need to validate some text boxes. But I only want to validate the text boxes, if the associated checkbox is checked.

yes, but do it this way:

for(var i=0; i<=20; i++){
if (window.document.form[&quot;check&quot; + i].checked == true){
// Do some stuff
}
}

The syntax would be document.formName[&quot;check&quot;+i].checked

I prefer naming all checkboxes the same and then referencing them like this, but that's just my preference:

size = formName.checkName.length;
for (i = 0; i < size; i++) {
   if (formName.checkName[i].checked) {
      //blah
   }
}
