executing multiple form onSubmit commands
I have a phone number validation script I'd like to use. However, it's written for one field. Would there be any way to make this script work with multiple fields composing a phone number?
<script language = "Javascript">
/**
* DHTML phone number validation script. Courtesy of SmartWebby.com (<a href="http://www.smartwebby.com/dhtml/" class="bb-url">http://www.smartwebby.com/dhtml/</a>)
*/
// Declaring required variables
var digits = "0123456789";
// non-digit characters which are allowed in phone numbers
var phoneNumberDelimiters = "()- ";
// characters which are allowed in international phone numbers
// (a leading + is OK)
var validWorldPhoneChars = phoneNumberDelimiters + "+";
// Minimum no of digits in an international phone no.
var minDigitsInIPhoneNumber = 10;
function isInteger(s)
{ var i;
for (i = 0; i < s.length; i++)
{
// Check that current character is number.
var c = s.charAt(i);
if (((c < "0") || (c > "9"))) return false;
}
// All characters are numbers.
return true;
}
function stripCharsInBag(s, bag)
{ var i;
var returnString = "";
// Search through string's characters one by one.
// If character is not in bag, append to returnString.
for (i = 0; i < s.length; i++)
{
// Check that current character isn't whitespace.
var c = s.charAt(i);
if (bag.indexOf(c) == -1) returnString += c;
}
return returnString;
}
function checkInternationalPhone(strPhone){
s=stripCharsInBag(strPhone,validWorldPhoneChars);
return (isInteger(s) && s.length >= minDigitsInIPhoneNumber);
}
function ValidateForm(){
var Phone=document.frmSample.txtPhone
if ((Phone.value==null)||(Phone.value=="")){
alert("Please Enter your Phone Number")
Phone.focus()
return false
}
if (checkInternationalPhone(Phone.value)==false){
alert("Please Enter a Valid Phone Number")
Phone.value=""
Phone.focus()
return false
}
return true
}
</script>Right now I have three individual fields that, upon submitted, make one.
<form name="form" action="https://real.cart.url.is.here/novacart.pl" onsubmit="javascript: exit=false; form.ship_phone.value = '(' + form.phoneArea.value + ') ' + form.phonePre.value + '-' + form.phoneNum.value; return ValidateForm()" method="post"> '
