After altering the value of a hidden form field with Javascript and clicking the
Reset button the value of hidden fields is not reset.

Reproducible: Always

Steps to Reproduce:
1.Load the URL
2.Click 'Show value' - An alert box should pop up with number 33 in it (that's
the default value of a hidden form field).
3.Click 'Set value ...'
4.Click 'Show value' again - the alert box should now show '66'
5.Click 'Reset' 
6.Click 'Show value'
Actual Results:  
Alert box displays number 66

Expected Results:  
Alert box should display number 33

Tested on Linux, Mozilla 2002082904.

Also tested with NS4.78 (Linux) and Opera 6.0 (Linux). Both display '66' after
step #6

Konqueror 3.0+ and IE5.5+ display '33' - which I believe is correct.

There are no defaultValue property on the hidden form element. (Also no form 
property) 
When .defaultValue is fixed on input type=text, this will become possible. 
Setting dependent.

I don't sure if this is a dup:
When I press F5 or Ctrl-F5 to reload the page, hidden fields are NOT resetted. 
Shouldn't they reparsed from the orginal HTML file? This annoy me very much and 
inconsistence with IE..

Will this fix in this bug or should I file another bug report?
That is this bug.
Er, wait, no it's not this bug.  Hasty me.  Best file another bug.
Dup of bug 158209?

Calling the reset() function does not reset hidden fields.  Can test with code
below:

<html>
<head>
<script language="JavaScript">
<!--
function showData(form) {
	var msg = "Form Data";
	msg += "\r\n\r\nHidden: " + form.hiddenval.value;
	msg += "\r\nText: " + form.textval.value;
	msg += "\r\nRadio: " + getRadioValue(form.radioval);
	msg += "\r\nCheckbox: " + form.checkboxval.checked;
	msg += "\r\nSelect: " + form.selectval[form.selectval.selectedIndex].value;;
	alert(msg);
}

function setHidden() {
	document.testform.hiddenval.value = "HiddenVal";
	alert("Hidden value now set to 'HiddenVal'");
}

function getRadioValue (radioButtonOrGroup) {
  var value = null;
  if (radioButtonOrGroup.length) { // group 
    for (var b = 0; b < radioButtonOrGroup.length; b++)
      if (radioButtonOrGroup[b].checked)
        value = radioButtonOrGroup[b].value;
  }
  else if (radioButtonOrGroup.checked)
    value = radioButtonOrGroup.value;
  return value;
}

// -->
</script>
</head>
<body>

<form name="testform">
<input type="hidden" name="hiddenval">
Text: <input type="text" name="textval"><br>
Radio: <input type="radio" name="radioval" value="radiodata1"> 1 &nbsp;&nbsp;
<input type="radio" name="radioval" value="radiodata2"> 2<br>
