Javascript pass value from select box to input box

JavaScript

Hi

I have a html/php web page and I have 2 Forms on it.

Form2 contains a select box and I was able to get the value from that just fine.

Form1 contains a php list of all users in a table.
I have a hidden field that I want to put the value of the select box in Form2 (

<form name=“Form2”>
<select name=“sortme” id=“sortme” onchange=“getValue(this);document.Form1.sortme2.value=this.value;”>
</form>

and pass that value to a hidden field I have in Form1 (on same page).

<form name=“Form1”>
<input type=‘text’ value=‘’ name=‘sortme2’ id=‘kath’>
</form>

How do I do this?

First you need to abandon the habit of addressing forms by the name; the attribute is deprecated except for the elements of forms.

The neatest way might be to use a function to address the desired element, by passing it the ID (not name) of its form, the name of the element and the value:

<form id='f1'>
  <input name='inp1' type=text>
</form>

<script type='text/javascript'>

function writeFormElem( formID, elemName, elemValue )
{
  var formRef = document.getElementById( formID );

  if( formRef && formRef.nodeName == 'FORM' && formRef.id == formID )
    formRef[ elemName ].value = elemValue;
  else
    alert( 'Invalid form ID:"' + formID + '"' );
}

writeFormElem( 'f1', 'inp1', 'OK' );

</script>
