How to clear the border color (preserving the existing one) ??

[PHPycho]

Hello Forums !!
I had following script for marking the fields with certain color border and clearing that color border , preserving the fields original border color.

<!-- Javascript -->
<script language="javascript">
function FMark(){
	document.forms['frm_mark'].test_field.style.border = "1px solid #ff0000";  
}

function FClear(){
	document.forms['frm_mark'].test_field.style.border = "none"; 
}
</script>
<!-- HTML -->
<form name="frm_mark" action="#" method="get">
<input type="text" name="test_field" style="border: 1px solid #0066FF" />
<input type="button" value="Mark" onclick="FMark();"/>
<input type="button" value="Clear" onclick="FClear();"/>
</form>

Whats my problem ?
- I am able to mark the field but also able to clear that marked one but couldnt preserve the existing border color

What I want ?
- I want to clear the marked border color preserving the existing border color ie #0066FF
Any Suggestion and Help are warmly welcome
Thanks in advance to all of you

Because you set the border to "none", aka. no border.

Try this:

<!-- Javascript -->
<script type="text/javascript">
function FMark(){
	document.forms['frm_mark'].elements['test_field'].style.border = "1px solid #ff0000";  
}

function FClear(){
	document.forms['frm_mark'].elements['test_field'].style.border = "1px solid #0066FF"; 
}
</script>
<!-- HTML -->
<form name="frm_mark" action="#" method="get">
<input type="text" name="test_field" style="border: 1px solid #0066FF">
<input type="button" value="Mark" onclick="FMark();">
<input type="button" value="Clear" onclick="FClear();">
</form>

Thanks MR.tech_support for the reply.
But one thing the color value is dynamic , its not fixed. so this method doesnt work..is there any alternatives
Thanks again

[tech_support]

What do you mean by dynamic? The colour will change in the style=""

Just don't specify a border in the clearing, like this:

function FClear(){
	document.forms['frm_mark'].elements['test_field'].style.border = ""; 
}
