I'm web designer w little experience in coding. Working on a form that has fields with check boxes to be checked. How can I include validation for these checkbox array in the validation_required function that I have for other areas?

Here is the code I have so far for the validations in the head for (onSubmit="return validate_form(this)" ) and the code for check boxes area in the body:
_______________________________

<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
  {alert(alerttxt);return false}
else {return true}
}
}function validate_form(thisform)
{
with (thisform)
{
if (validate_required(company_name,"Company name must be filled out!")==false)
  {company_name.focus();return false}
if (validate_required(address,"Company address must be filled out!")==false)
  {address.focus();return false}
if (validate_required(city,"City must be filled out!")==false)
  {city.focus();return false}
if (validate_required(state,"State must be filled out!")==false)
  {state.focus();return false}
if (validate_required(zip,"Zip code must be filled out!")==false)
  {zip.focus();return false}
if (validate_required(country,"Country name must be filled out!")==false)
  {country.focus();return false}
if (validate_required(company_phone,"Phone must be filled out!")==false)
  {company_phone.focus();return false}
if (validate_required(company_email,"Company email must be filled out!")==false)
  {company_email.focus();return false}
if (validate_required(tax_id_number,"Federal Tax ID Number must be filled out!")==false)
  {tax_id_number.focus();return false}
 
}
}
</script>

This is the checkbox area in the body:

HTML Code:

<tr>
<td colspan="4" valign="top">
<input name="employees_count" type="checkbox" id="a" value="1-9" />1-9 
<input name="employees_count" type="checkbox" id="b" value="10-25" />10-25
<input name="employees_count" type="checkbox" id="c" value="26-50" />26-50
<input name="employees_count" type="checkbox" id="d" value="51-100" />51-100
<input name="employees_count" type="checkbox" id="e" value="101+" />101+
</td>
</tr>

What kind of validation do you need? Should only one box be checked? If so, I recommend using radio buttons instead.

I need to have option to check more than one box, that is why I want to use the checkboxes instead of radio buttons.

Ok, and you just want to check to make sure atleast one box is checked, right?

[Jooba]

Yes. That will do.

Try this:

<script type="text/javascript">
function validate_required(field,alerttxt)
{
    with (field)
    {
    if (value==null||value=="")
      {alert(alerttxt);return false}
    else {return true}
    }
}
function validate_form(thisform)
{
    with (thisform)
    {
    if (validate_required(company_name,"Company name must be filled out!")==false)
      {company_name.focus();return false}
    if (validate_required(address,"Company address must be filled out!")==false)
      {address.focus();return false}
    if (validate_required(city,"City must be filled out!")==false)
      {city.focus();return false}
    if (validate_required(state,"State must be filled out!")==false)
      {state.focus();return false}
    if (validate_required(zip,"Zip code must be filled out!")==false)
      {zip.focus();return false}
    if (validate_required(country,"Country name must be filled out!")==false)
      {country.focus();return false}
    if (validate_required(company_phone,"Phone must be filled out!")==false)
      {company_phone.focus();return false}
    if (validate_required(company_email,"Company email must be filled out!")==false)
      {company_email.focus();return false}
    if (validate_required(tax_id_number,"Federal Tax ID Number must be filled out!")==false)
      {tax_id_number.focus();return false}
     
    }
    var cBoxes=document.getElementsByName("employees_count");
    var isChecked=false;
    for(var i=0;i<cBoxes.length;i++)
    {
        if(cBoxes[i].checked){
            isChecked=true;
            break;
        }
    }
    if(!isChecked){
        return false;
    }
}
</script>

Hi TwoD,
just to let you know I tried your script but it still would not work correctly, so I changed the field to a List/Menu and added the code below to the script which worked. But anyway thanks for your help. Jooba

}
   else if (value==null||value==""||value=="Select from list below"){
    alert(alerttxt);
    return false;
       }
   else {return true}
_______________________________
 
if (validate_required(employees_count,"Number of employees must be selected from the list!")==false)
  {employees_count.focus();return false}

Ok, what did not work? Any errors? Ctrl+Shift+J in FF to bring up the error console.
