/*
Javascript to be used for checking a form before submission.
To use this page, in form to be checked add onSubmit="return checkForm(this)"
If you wish to do additional checks create a new function that performs the additional checks
eg function myFormCheck(callingForm) {
	var isOK = checkForm(callingForm);
	if (isOK){
		additional code to check the form and set value of isOK
	};
	return isOK;
}

For the checks to be made the following parameters must be added to the form controls
message="?" -- The message to show should the control fail any of the tests.
required="yes/no" -- Is a value required for this control.
rejectvalues="?" -- A comma delimited list of values for this control to reject (text,password,select)
validate="date/eurodate/emailaddress/creditcard/time/integer/float/telephone" -- What type of value is alllowed in this control. If telephone will accept numbers, spaces, - sign and + sign as first character after spaces removed
range="?,?" -- 2 comma seperated values for minimum(1st) and maximum(2nd)
matchto="?" -- Name of control this value must match, usually for password and confirm password
greaterthan="?" -- Name of control this value must be greater than, usually used for range selection controls
greaterorequalto="?" -- Name of control this value must be greater than or equal to, usually used for range selection controls
higherorequalindexthan="?" -- Name of select control that this select control must have a higher or equal selected index
filesuffix="?" -- Comma delimited list of of suffixes to allow for file upload controls, e.g. "doc,txt,rtf"
minlength="?" -- Integer for minimum number of characters to be used. (text,password)
oldvalue="?" -- Used on evaluate="creditcard". If control value is same as oldvalue then creditcard value is not evaluated. This is used as you do not show credit cards value again on site, usually just last 4 characters.
