Jquery Validate Phone Number With With Regex

jQuery validate phone number with with RegEx

Your regex works fine for me... you could shorten it to just /[0-9]{10}/.

Your problem is here:

$("#call_number").val().length < 1. If the number is 10 characters long, it will never be less than 1, no?

You probably meant something like this:

$("#call_number").val().length === 10

jQuery Phone Regex Validation

You need the following regex:

/^\+(?:\d(?:\(\d{3}\)|-\d{3})-\d{3}-(?:\d{2}-\d{2}|\d{4})|\d{11})$/

See the regex demo

The regex you have ^\+d{1}(\d{3})\d{7}$ has d instead of \d (thus failing to match digits) and unescaped parentheses (thus the pattern did not match literal parentheses).

Breakdown:

• ^ - start of string
• \+ - a literal + symbol

• (?:\d(?:\(\d{3}\)|-\d{3})-\d{3}-(?:\d{2}-\d{2}|\d{4})|\d{11}) - two alternatives:

  • \d(?:\(\d{3}\)|-\d{3})-\d{3}-(?:\d{2}-\d{2}|\d{4}):
    
    
    • \d - a digit
    • (?:\(\d{3}\)|-\d{3}) - either (123) like substring or -123 substring
    • -\d{3} - a hyphen followed with 3 digits
    • - - a hyphen
    • (?:\d{2}-\d{2}|\d{4}) - 2 digits followed with a hyphen and 2 digits or 4 digits
  • | - or
  • \d{11} - 11 digits

• $ - end of string

Example of a regular expression for phone numbers

Use this rexeg

/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/

• (123) 456 7899
• (123).456.7899
• (123)-456-7899
• 123-456-7899
• 123 456 7899
• 1234567899

Jquery form validation - telephone number

I would highly recommend using jQuery validate rather than re-inventing the wheel

a quick google search for uk numbers with jquery validate turned this up

filters

that looks like this

jQuery.validator.addMethod('phoneUK', function(phone_number, element) {
  return this.optional(element) || phone_number.length > 9 &&
  phone_number.match(/^(\(?(0|\+44)[1-9]{1}\d{1,4}?\)?\s?\d{3,4}\s?\d{3,4})$/);
  }, 'Please specify a valid phone number'
);

Modify given regex to check if string contains no phone number

Following the logic from our chat, here is the pattern:

/^(?!.*(?:\s|^)(?:\+\d|0)(?:[()-]*\d){6,}(?!\S))/

See the regex demo.

Details:

• ^ - start of string
• (?! - start of a negative lookahead:
  
  • .* - any zero or more chars other than line break chars, as many as possible
  • (?:\s|^) - whitespace or start of string
  • (?:\+\d|0) - + and a digit, or a zero
  • (?:[()-]*\d){6,} - six or more occurrences of zero or more (, ) or - chars and then a digit
  • (?!\S) - no non-whitespace char allowed immediately to the right of the current location
• ) - end of the lookahead check.

},
