Here are the two JS functions you are looking for. I'll assume you know how
to use them :)
--------------------------------------------------------------
function isInteger(str){
if( str.length == 0 )
return false;
for( i=0; i<str.length; i++ ){
if( str.charAt(i) < "0" || str.charAt(i) > "9")
return false;
}
return true;
}
function isDate(str){
if( str.length != 8 )
return false;
// find the month
month = str.substring(0,2);
day = str.substring(3,5);
year = str.substring(6,8);
// check for integers
if( !(isInteger(month) && isInteger(day) && isInteger(year)) )
return false;
// determine how many days are in this month
maxDay = 31;
if( month == 4 || month == 6 || month == 9 || month == 11 ) maxDay =
30;
else if( month == 2 ){
if( year % 4 > 0 || (year % 100 == 0 && year % 400 > 0) )
maxDay =28;
else maxDay = 29;
}
// check ranges
if( month < 1 || month > 12 )
return false;
if( day < 1 || day > maxDay )
return false;
// if we made it this far it's a good date
return true;
}

I am in desperate need of a simple validation of two types of form fields.
1. Date field (not a cfform just a plain form) - must validate that data
entered is a date
2. Number field (not a cfform just a plain form) - must validate that data
entered is a number
Thanks
