用于验证邮政编码和电话号码的正则表达式

Question

I am creating a form, with warning elements. All works great but need to define my patterns better.

                $("#postcode").inputNotes( 
              {
                warning: {
                  pattern: /^[0-9]+$/,
                  type: 'note',
                  text: 'Only numbers, please ...',
                  inversedBehavior: true
                }
              }
            );
            $("#phone").inputNotes( 
              {
                warning: {
                  pattern: /^[0-9]+$/,
                  type: 'note',
                  text: 'Only numbers, no spaces please ...',
                  inversedBehavior: true
                }
              }
            );

Ok for the Postcode warning, I want the pattern to expect 4 numbers

For the Phone warning, I want the pattern to expect 10 numbers.

Any help appreciated.

Answer 1

Here are the rules for Australian postcodes:

ACT: 0200-0299 and 2600-2639.

NSW: 1000-1999, 2000-2599 and 2640-2914.

NT: 0900-0999 and 0800-0899.

QLD: 9000-9999 and 4000-4999.

SA: 5000-5999.

TAS: 7800-7999 and 7000-7499.

VIC: 8000-8999 and 3000-3999.

WA: 6800-6999 and 6000-6799

Regular Expression: ^(0[289][0-9]{2})|([1345689][0-9]{3})|(2[0-8][0-9]{2})|(290[0-9])|(291[0-4])|(7[0-4][0-9]{2})|(7[8-9][0-9]{2})$

Pass: 0200|||7312|||2415

Fail: 0300|||7612|||2915

Answer 2

Australia Post has greatly simplified the rules in 2019. You now only need to account for the ranges:

So the Regular Expression for Validating Australian Postcodes is just:

^(0[289][0-9]{2})|([1-9][0-9]{3})$

Answer 3

Update:

For 6 digit or 10 digit numbers: pattern: /^[0-9]{10}|[0-9]{6}$/,

For four digit Postcode: pattern: /^[0-9]{4}$/,

For 10 digit Phone number: (if phone number can't start with 0) pattern: /^[1-9][0-9]{9}$/,

(if phone number can start with 0) pattern: /^[0-9]{10}$/,

Answer 4

For a 4 digit postcode, you can use /^\d{4}$/ .

For a 10 digit postcode, you can use /^\d{10}$/ .

Keep in mind some people will type spaces, parenthesis etc into the phone number. You should strip all non digits first before validating with /[^\d]+/g .

Answer 5

Instead of using the + modifier, try using {num} , where num is the number of instances of the previous atom you want.

Answer 6

All these answers are assuming that you limit the text field to 4 characters eg. (12345) is valid, to limit the length use the following

^(0[289][0-9]{2})$|^([1-9][0-9]{3})$

Answer 7

just to save people time here is an example of how to use in jquery

 $("#address-postal-code").once().on('blur', function (e) {
    var myRegEx = new RegExp('^(0[289][0-9]{2})|([1-9][0-9]{3})$');
    var ele = $(this);
    if (!myRegEx.test(ele.val())) {
        console.log('no good');
    }
    else {
        console.log('good');
    }
})
