Regular expression to check phone number contains 10 zeroes in javascript

Question

I have a regular expression to check phone number.It returns 'true' for 10 zeroes. How to change regular expression to return 'false' for 10 zeroes. Following is my code

var phoneno = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;

phoneno.test('8129587912');// returns true .Works good

phoneno.test('asdff');// returns false .Works good

phoneno.test('0000000000');//returns true. Not Working As Expected

Please help to solve this issue.

How does `phoneno.test('asdff')` match fine? What is your objective here? It's a bit confusing. You want to allow phone numbers but not one that contains 10 zeroes? — degant, May 11 '17 at 05:06
@degantSorry for the mis-leading comment in the code.I have edited my question. — Rahul K R, May 11 '17 at 05:08
You can use this ^[789]\d{9}$ regex for validating Indian mobile number — Nitin Dhomse, May 11 '17 at 05:09
Why aren't you using one of the many tried and tested regexes for phone number validation? — Robert McKee, May 11 '17 at 05:14
@NitinDhomse I cannot restrict the phone numbers to 'Indian phone numbers'. — Rahul K R, May 11 '17 at 05:16
`I cannot restrict the phone numbers to 'Indian phone numbers'.` - well, why are you restricting the test to 10 digits? that's an arbitrary number of digits in the first place — Jaromanda X, May 11 '17 at 05:24
@JaromandaX I am new to regex. I got this regex from stack overflow .I just used it.Thats all. — Rahul K R, May 11 '17 at 05:30
@RahulKR - your question specifically asks about 10 digit phone number - I'm sorry I can't guess that you actually didn't write that code in the first place, so your issue is that you don't understand *RegEx101* — Jaromanda X, May 11 '17 at 05:30
@JaromandaX Yes.I tried some tutorials but it was hard to follow those as a beginner.Can you suggest one for beginner? — Rahul K R, May 11 '17 at 05:35
no, because I find google search finds these sort of tutorials for you, and you can even select what (spoken) language the tutorial is in if you search for yourself — Jaromanda X, May 11 '17 at 05:36

This is what you asked for:

var phoneno = /^(?!0000000000)\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;

It does exactly what he asked. Nothing more, nothing less. It's a bad implementation, but it is what he asked for. – Robert McKee May 11 '17 at 05:20

If just want exclude 10 zeros circumstance, you can make a special case for that:

if( !/0{10}/.test(phonenum) ){
    //another rules...
}
