How to validate an array of checkboxes named in ASP?

[Rachel80]

Hi,

i have an array of 19 checkboxes as follows:

<% dim temp_id(19)

for i=0 to 18
temp_id(i) = &quot;id&quot; & i
next

for j=0 to 18 %>
<input type=&quot;text&quot; name=&quot;<%=temp_id(j)%>&quot; size=15 maxlength=&quot;20&quot;>
<% next %>

As shown, each checkbox has a unqiue name (eg. id1, id2, ..)
Thus I wonder in JS, how can i validate all the checkboxes?
say,

if (form.id1.value.length == 0)
{
alert(&quot;Empty field not allowed&quot;
form.id1.focus();
return false
}

I do not want to repeat this 19 times as i want to use arrays.. However, the form name for the checkboxes are in
<%=temp_id(j)%> this format, how can i do the validation? Pls help, thanx!

Here's how you can validate input type=&quot;text&quot; (untested - from memory):

    <input type=&quot;text&quot; name=&quot;<%=temp_id(j)%>&quot; size=15

function chkMe() {
  var howmany = 19;
  for (i = 1; i < howmany; i++) {
    fld = eval('document.forms[0].id' + i);
    if (fld.value.length == 0) {
      alert(&quot;Empty field not allowed&quot;);
      fld.focus();
      return false;
    }
  }
}
