Hi,
I am looking for a javascript / jQuery code for phone number validation if the phone number has all 0’s in it.
If the value entered is only zeros, it should display the “Enter a valid value” message.
I want to prohibit 0, 00, 000000, 000-000-0000, 000.000.0000, etc. ( All possible phone number formats )
Can anyone help me in it?
Thanks,
Devesh
The following is the jQuery validator for US-phone validation
jQuery.validator.addMethod("phoneUS", function(phone_number, element) {
phone_number = phone_number.replace(/\\s+/g, "");
return this.optional(element) || phone_number.length > 9 &&
phone_number.match(/^(1-?)?(\\([2-9]\\d{2}\\)|[2-9]\\d{2})-?[2-9]\\d{2}-?\\d{4}$/);
}, "Please specify a valid phone number");
$("#myform").validate({
rules: {
field: {
required: true,
phoneUS: true
}
}
});
Thanks friend,
But I need it for standard international format, mostly for EU countries.
Can you help me?
Please go through the below mentioned code and let me know if you can modify it to my requirements -
Thanks.

Well, do you see the regular expression?
/^(1-?)?(\\([2-9]\\d{2}\\)|[2-9]\\d{2})-?[2-9]\\d{2}-?\\d{4}$/
That means:
[list][]^ this is the start of the number
*? an optional non-zero digit
[][2-9]\d{2} 3-digits from 200 upwards
* optional parenthesis for area code
[]-? optional divider
[][2-9]\d{2} 3-digits from 200 upwards
[]-? optional divider
[]\d{4} four more digits
[*]$ end of the number[/list]
When you figure out what formats are acceptable and which are not, we can craft together a regular expression for you that will make matching them a breeze.
If you want to accept phone numbers from anywhere at all then there are not very many restrictions you can apply to them as different countries use different formats. There are even a few valid phone numbers that consist of nothing but zeros.
Thanks all for the suggestions.
I have completed the phone no. validation code.
Some features are -

I need further help.
Right now I am using hardcore values for comparing all 0’s.
Can anyone provide me a regular expression for comparing only 0’s in a phone number.
Thanks
Yes.
Sometimes it’s better to look for the opposite of what you’re after, and then invert it.
In this case, invert a positive match for all zeros.
if (!text.match(/^0+$/)) {
That doesn’t take into account that 000 is a valid phone number.
