Need help array validation

[justspree]

Hi, I have a form dynamic output by php like this:

<input name="field[36]" id="field[36]" type="text" size="1" class="textfield" value="2" />
<input name="field[36]" id="field[36]" type="text" size="1" class="textfield" value="2" />
<input name="field[80]" id="field[80]" type="text" size="1" class="textfield" value="1" />
<input name="field[110]" id="field[110]" type="text" size="1" class="textfield" value="1" />

I'm trying to use javascript to loop through the fields. Is there a way to do it? I can do this php easily:

while( list( $key, $value ) = each( $_POST['field'] ) )

<input name="field[]" type="text" size="1" class="textfield" value="2" />
<input name="field[]" type="text" size="1" class="textfield" value="2" />
<input name="field[]" type="text" size="1" class="textfield" value="1" />
<input name="field[]" type="text" size="1" class="textfield" value="1" />
<input type="button" onclick="checkAll()" />
 
<script type="text/javascript">
  function checkAll(){
    var fields=document.getElementsByName('field[]');
    for(i=0; fields.length; i++){
        alert(fields[i].value);
    }
  }
</script>

This won't work on IE6 though; to make it work on obsolete browsers, you can loop through document.form_name.elements and check for element name.

Thanks daemon, but I can't do this 'field[]', I need the key intact as in field[110]. Is there anyway to do that?

OK, I will believe you must specify the indices. Then you could loop through the form elements and use substr to check the first characters of the name.

<script type="text/javascript">
  function checkAll(){
    var fields=document.myform.elements;
    for(i=0; fields.length; i++){
        if(fields[i].name.substr(0,5)=='field'){
            alert(fields[i].value);
        }
    }
  }
</script>
