I know how to get the maximum of a field but how can I get a max & minimum value for a form field.
Let's say I have a serialnumber field thet needs exactly 10 characters. I need it to be exactly 10 characters.
Is this done via javaScript or can it be done with CFScript?

I want to thank you in advance,
Gene

Little better:

<cfsavecontent variable="checklength">
if(serialnumber.length != 10)
{
alert("Serial Number must be 10 characters!", "Serial Number Error");
submit.enabled = false;

}
else
{
submit.enabled = true;

}
</cfsavecontent>

<cfform format="flash" id="myForm" name="myForm" method="post"
action="somepage.cfm">
<p>
<cfinput type="text" name="serialnumber" id="serialnumber"
onBlur="#checklength#" />
</p>
<p>
<cfinput type="submit" id="mysubmitSubmit" name="submit" value="Submit"
enabled="false" />
</p>
</cfform>

Wow don't do Flash forms so this is a SWAG from reading this:

http://www.adobe.com/devnet/coldfusion/articles/adv_flashforms.html

<cfsavecontent variable="checklength">
if(serialnumber.length != 10)
{
submit.enabled = false;
}
else
{
submit.enabled = true;
}
</cfsavecontent>

<cfform format="flash" id="myForm" name="myForm" method="post"
action="somepage.cfm">
<p>
<cfinput type="text" name="serialnumber" id="serialnumber"
onchange="#checklength#" />
</p>
<p>
<cfinput type="submit" id="mysubmitSubmit" name="submit" value="Submit"
enabled="false" />
</p>
</cfform>

Ken,
The business request is to NOT wait for server side validation.
That is a business rule that is out of my hands.

Then let me clarify Dan,

I am using Flash forms from CF7.2.
The existing Javascript code that was here does not work.
-----------------------------------<script type='text/javascript'>
function lengthRestriction(elem, min, max){
var uInput = elem.value;
if(uInput.length >= min && uInput.length <= max){
return true;
}else{
alert("Please enter 10 EDI Numbers");
elem.focus();
return false;
}
}
</script>
<form>
<input type='text' id='restrict' maxlength="10"/>
<input type='button'
onclick="lengthRestriction(document.getElementById('restrict'), 10, 10)"
value='Check Field' />
</form>
--------------------------------------

Is there a solution for flash forms?
I hope that will clarify my question.

And you should do it server-side too.

<cfif Len(Trim(FORM.yourfield)) NEQ 10>
Your error code here
</cfif>
