I would like to be able to reset all form values to the default values apart from the textfield on submit, if  href id="filter" reads Filter. if href id="less" then the form should submit all entered values.
<html>
<head>
 
<title>Untitled Document</title>
<script type="text/javascript">
 
function show_adv() {
 
	if (document.getElementById("adv").style.display=='none') {
	document.getElementById("adv").style.display='';
	document.getElementById("filter").innerHTML = 'Less';
	}
	else  {
	document.getElementById("adv").style.display='none';
	document.getElementById("filter").innerHTML = 'Filter';
	}
 
}
 
</script>
</head>
 
<body>
 
<form action="" method="POST">
  <table width="899" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="860" style="padding-bottom:10px;"><input name="textfield" type="text" id=""  size="30" />          <input name="" type="button" /></td>
    <td style="padding-bottom:10px;"><a href="#" id="filter" class="style46" onclick="show_adv();">Filter </a></td>
  </tr>
  <tr>
    <td colspan="2" id="adv" style="display:none;">
    <table width="100%" border="0" style="background-color: #D6ECD2">
  
  <tr>
  <td colspan="7" class="style2" style="padding:10px;">Query the following:<br/>
  <label><input name="Title" type="checkbox" disabled value="Title" checked />Title</label>
  <label><input name="Title" type="checkbox"  value="Tags" checked />Tags</label>
  <label><input name="Title" type="checkbox"  value="Description" checked />Description</label>
  <label><input name="Title" type="checkbox"  value="Uploader" checked />Uploader</label>
  </td>
  </tr>
  
  
  <tr>
    <td colspan="7" class="style2" style="padding:0px 10px 10px 10px;">Uploaded: <br/>
  <select name="no_of_student" id="no_of_student">
  <option selected="selected">Anytime</option>

That just resets the entire form, i am looking to reset all form fields aside from the first field on submitting the form if filter says "less", otherwise the form should not be reset.

if (  document.getElementById("filter").innerHTML == 'Filter' )
{      var txtval = document.form_name.textfield.value;
       document.form_name.reset();
        document.form_name.textfield.value = txtval;
}

you have to give the form a NAME, and replace form_name with that name in the above, and it will work.
