code that only works with certain elements 1

[optjco]

Hi,
I have this code for disabling a submit button on an ASP page however although I only call it from one element if any of the other elements are empty then i cannot enable the button.

Could someone tell me if it is possible to only action the code from one textfield Please

<script Language = "javascript">
// Start Insert Complaint ID Function
function MoveCID()
{
var myVar = document.frmBoard.cmbComplaint.value
document.frmBoard.txtCID.value = myVar;
}// End Insert Complaint ID Function
</script>
<script Language = "javascript">
function maybeDisableButton()
{
 var dfe = document.frmBoard.elements;
 var disableButton = false;
 for(var i=0; i<dfe.length; i++)
 {
  if(dfe[i].value.length < 5)
  {
   disableButton = true;
   break;
  }//end if
  else
  {
   disableButton = false;
  }//end else
 }//end for

 document.frmBoard.Submit.disabled = disableButton;
}//end maybeDisableButton()
</script>

code to call function

onKeyUp = "maybeDisableButton()"

If you only need for it to check one textbox, then you could make it much simpler...

function maybeDisableButton(){
  if (document.frmBoard.txtCID.value == "someValue){
    document.frmBoard.Submit.disabled = false
  }
  else{
    document.frmBoard.Submit.disabled = true
  }
}

mwolf00,
sorry I mislead you there slightly I posted two bits of javascript code, the code I need to amend is as follows

<script Language = "javascript">
function maybeDisableButton()
{
 var dfe = document.frmBoard.elements;
 var disableButton = false;
 for(var i=0; i<dfe.length; i++)
 {
  if(dfe[i].value.length < 5)
  {
   disableButton = true;
   break;
  }//end if
  else
  {
   disableButton = false;
  }//end else
 }//end for

 document.frmBoard.Submit.disabled = disableButton;
}//end maybeDisableButton()
</script>

All i need is to make sure that a textarea("txtDetails" is populated with at least 5 characters.

I would appreciate it if you could point me in the right direction

This will do it, but it is more complex than it needs to be...

<script Language = "javascript">
function maybeDisableButton()
{
 var dfe = document.frmBoard.elements;
 var disableButton = false;
 for(var i=0; i<dfe.length; i++)
 {
  [b][COLOR=blue]if (dfe[i].name == "txtDetails"){[/color][/b]
   if(dfe[i].value.length < 5)
   {
    disableButton = true;
    break;
   }//end if
   else
   {
    disableButton = false;
   }//end else
  [b][COLOR=blue]}[/color][/b]
  
 }//end for

 document.frmBoard.Submit.disabled = disableButton;
}//end maybeDisableButton()
</script>

mwolf00,
works great thanks a lot, just one more question ? on my page I have 15 fields would it be possible to use the code to make sure that say 3 fields were populated or would I need the javascript code in there 3 times. Sorry for all the questions but I am trying to learn as I go along
