getting the value of a select box to confirm delete.

javascript is definately one of my weak points. i have a select box with the options of 'edit' and 'delete'.

i need to run a confirm javascript only if 'delete' is selected.

here's the javascript:

Code:

<SCRIPT type="text/javascript">
<!--
function verifyDelete(id)
{
  if(confirm("Are you sure you want to delete this item?"))
    return true;
  else
    return false;
}
-->
</SCRIPT>

and here's my form:

Code:

<form method=post action=http://codenewbie.com>

<select name=modify>
<option value=edit32>edit</option>
<option value=delete32>delete</option>
</select>
<input type=submit name=submit value=submit onClick="return verifyDelete()">

</form>

i guess this isn't a real good question .. ok, here is my question..

how can i send the value of 'modify' in the arguments of my verifyDelete() function?

once i can do that, it will be easy to check for 'delete' in the js function before i call the confirm().

solution:

Code:

<HTML>
<head>

<SCRIPT type="text/javascript">
<!--
function verifyDelete(modify)
{  
  if(modify.value == "delete")
  { 
    if(confirm("Are you sure you want to delete this item?"))
      return true;
    else
      return false;
  }
  else
  {
    return true;
  }
}
-->
</SCRIPT> 
</head>

<BODY>
<form method=post action=http://codenewbie.com onSubmit="return verifyDelete(this.modify);">

<select name=modify>
<option value=edit>edit</option>
<option value=delete>delete</option>
</select>
<input type=submit name=submit value=submit>

</form>
</BODY>
</HTML>
