Hi there I have a form,  which has 6 dropdowns,  15 Checkboxes and  A Text Field. I would like to know how to code a javascript function that will loop through these elements and reset each one.

Many Thanks

This will give you an idea of how to loop through all elements and read different properties. Now you would just have to add code to change whatever you wish -

You do not need javascript to reset a form to its initial state. All you need is a field of type "reset":
<input type="reset" value="Start Over" />

Or you could put all of the default values into something like below and have them changed when a reset button gets pressed.

<html>
<head>

<script type='text/javascript'>
function resetvalues() {
var seloption = document.getElementById('taxlist');
 seloption.selectedIndex=0;
 seloption = document.getElementById('joblist');
 seloption.selectedIndex=0;
 document.getElementById('firstname').value = " ";
 
}
</script>
</head>
<body>
<select id='taxlist'>
<option value=0>select tax code</option>
<option value=1>tax 1</option>
<option value=2>tax 2</option>
</select>
<br />
<br />
<select id='joblist'>
<option value=0>select job code</option>
<option value=1>job 1</option>
<option value=2>job 2</option>
</select>
<br />
<br />
<input type='text' id='firstname' />
<br />
<br />
<input type='button' value='reset all values' onclick='resetvalues();' />
</body>
</html>

do ad below,

function resetForm(formId){

var inputs = document.getElementById(dialogId).getElementsByTagName('input')
for(var x in inputs)
if(inputs[x].type="text")
inputs[x].value = ''
if(inputs[x].type="checkbox")
inputs[x].chacked=false
......
}

so on u continue for any form elements with input
for select just have the getElementsByTagName changes to "Select"..

Hope this helps

The purpose of the type="reset" is to set the form to its original state when it loaded from the server. Thus, if any field loads up with a specified value at load time, its value is then changed, and finally the "reset" button is pressed, it will rever to its original value. The "reset" button resets all the elements no just text fields. To reset does not necessarily mean "to blank out". I believe you are trying to "blank out" all the fields.
If at all possible, you could load up the form so that initally the "blank" option on the dropdown is blank.
