[FX.php List] RE: Re: Problem with Javascript validating

[Kim Hawksworth]

Andrew, Thank you very much!   Both methods resolve the issue.  I chose to
put the checkboxes into a variable (your relavation) in order to make the
code a bit more compact.

Thanks again for your help.

The code won't work because to the javascript, 'en_trial_yes[]' is the name
of the checkboxes.  Only PHP recognizes the [] in the name and creates an
array from the form.  The problem is you cannot use [] in javascript without
escaping it, so this is the only way I've found to get to the checkboxes:

 

1. Place the form in a variable ('frm' below)

2. Reference the checkboxes with this: frm['en_trial_yes[]']

3. You can then use this name just like you would any other variable

 

<!-- Code -->

var frm = document.newConsult;

var IsEnteralReason = "";

 

  for (var i = 0; i < frm['en_trial_yes[]'].length; i++) {

  if (frm['en_trial_yes[]'][i].checked) {

  IsEnteralReason = frm['en_trial_yes[]'][i].value;

  }

      }

      

 if (IsEnteralReason == "") {

 

 alert ("Please indicate the reason(s) the enteral trial was
unsuccessful!");

 return false;

 }

<!-- End Code -->

 

I had a revelation while typing this. I haven't tested it yet, but this
might/should work:

1. Put the checkboxes in a variable (ie: var en_trial =
document.newConsult['en_trial_yes[]'];)

2. And then use en_trial as the checkbox name in javascript (ie;
IsEnteralReason = en_trial[i].value;).

If you try this, let us know how it turns out.
