/*
This script can be used to validate a form or a control.
This script requires jQuery.
To load this script, use the following:
<script language="JavaScript" src="validation.js"></script>
<script language="JavaScript">
var valid = new validate();
</script>
The form definitions should be as follows:
<form method="POST" action="targetPage" name="FormName" id="FormName" onsubmit="return valid.validateForm(this);">
Items to be validated should be described as follows:
<label for="FacilityState">Facility State</label>
<input type="text" name="FacilityState" id="FacilityState" class="a list of validations and other classes" size="3" onchange="javascript: valid.validateInput(this);">
<div id="FacilityStateError" class="validationError" style="display:none;"></div>
You might be able to use onblur events but if you display a popup, that gets to be problematic and by default, this script creates a popup.
You can also put a div as follows on your page to display any validation errors from the form:
<div id="ValidationError" class="validationError" style="display: none;"></div>
Valid validations are:
required
email
date - in dd-mon-yyyy, dd-mm-yyyy, yyyy-mon-dd or yyyy-mm-dd formats
time
currency
numeric
alphanumeric
alpha
phone
state
zipcode
urlentry
Valid controls are:
text
testarea
select - Required only, value not '' or 0
radio buttons - one must be checked
