You tend to annoy users when they don't know the correct format you want for your mobile no. I only check that the user has entered only digits.

JavaScript

if (! /^\d+$/.test(mobile) ){
//This does not contain digits.
}

//or if you want to check for a certain number of digits

if (! /^\d{8}$/.test(mobile) ){
//This string does not have 8 digits.
}

Solution 1

use the regular expression in jquery and try with this expression /^[0-9]+$/.

Try these http://jquerybyexample.blogspot.com/2012/05/validate-phone-numbers-using-jquery.html[^]

This regex allows any number of digits. He said it should be 10 max. There should obviously be a minimum too, but that was not stated.

The second link gives in here states the limitation of the phone number. I think this could be used to limit the numbers to maximum or minimum.
