Using JQuery to validate a form

[sneakyimp]

I have a form with id = "resource_form".

It has a lot of inputs and I'd like to avoid having to put an id on each input.

How can I access an input named "foobar" in the form with id "resource_form". Something like this:

<script type="text/javascript">
  function validate() {
    // need to check the value of foobar here
  }
</script>
<form method="post" onsubmit="return validate();">
  <input type="text" name="foobar" value="arrggh">
</form>

document.getElementById('resource_form').elements['foobar']

Thanks, weedpacket. I have been asked to show some jQuery skills rather than straight HTML. This appears to work reasonably well:

var title = $("#resource_form").find("input[name$='foobar']").val();
