help me to correct the us zip code validation using javascript

Hi experts,

i want to format the given value to us zip code.For this i write this function

function formatZipOrPostalCode(source,textValue)
            {
            var textValueId = source;
            var codeValue = textValue.Value.replace("-","");
            var formatedCodeValue = codeValue.replace(" ","");
            if(formatedCodeValue.length == 5)
                  {
                  var searchPattern = /^(?(^00000(|-0000))|(\d{5}(|-\d{4})))$ /;
                  if(formatedCodeValue.search(searchPattern) ==-1)
                  {
                  textValue.IsValid = false;
                  }
                  else
                  {
                  document.getElementById(textValueId).value = formatedCodeValue;
                  textValue.IsValid = true;
                  }
                  return;
            }
}

Whe i run this script o got the error invalid Quantifier ?.How can i solve this

My aim is to not allow the entry 00000 and 00000-0000 only allow 11111 12345-1254 like values.Not fully zeroes

Thanks

Hi,

i have a mistake in the above search patern

The correct searchPattern that i cuurently gave is

searchPattern = /^(?(^00000)|(\d{5}))$ /;

DreamMaster

function isValidZipCode(value) {
var re = /^\d{5}([\-]\d{4})?$/;
return (re.test(value));
}

^\d{5} tells you that the regular expression must start ("^") with exactly five ("{5}") digits ("\d").
([\-]\d{4})?$ tells you that the grouping can appear either zero or one time ("?") and must be the end of the string ("$"). Inside this grouping is where the literal dash character ("-") must be, but since that character normally means other things in regular expressions, it needs to be "escaped" with the slash in front). After the dash is exactly four ("{4}") digits ("\d").

So, a value of "12345" will succeed. Any letter will cause the expression to fail. A value of "12345-6789" will succeed. If the 9 digit format is used, then the previous format (5 digits, dash, 4 digits) must be used. Other formats will fail.

Hope this helps,

Regards,
Max.

Hi,

Thanks for the reply .But if we use the above one it will accept 00000 and 00000-0000

It will not occur thats my requirement......

Thanks

DreamMaster

How about this then:

function isValidZipCode(value) {
var re = /^[1-9]{5}([\-][1-9]{4})?$/;
return (re.test(value));
}

Hi Max.,

if we use the above i was not able to enter this type os zip code.

and not allowed only these 2 cases
1) 00000
2)00000-00000 all others are allowed

Many Thanks

Hi,

This is for sure works. Please see the solution..
var re = /^[1-9]+\d{4}/;
return (re.test(formatedCodeValue));

Thanks.

sankar,

The specification has changed. What I gave works for any zip code like 11111-1111 to 99999-9999 however it won't work for 99999-9999.X

Rajesh, I am not a native american so I can't guess what possible combinations need to work, so if you don't tell me that something like 10111-0021.I needs to work as well, it's going to be very hard for me to help you properly ;)

Regards,
Max.

Hi Max,

The Exact requirement of mine is that
The zip code can allow to enter the values
1)only digits
2)it can be the combination of 5 digits or 5digits-4 digits
for eg: 11111-1111 or 11111
3)not allow only this type of values 00000, 00000-0000
4)all other combination of 0 with other digits are allowed

Many Thanks
Rajesh
