JS Phone Number Validation
The validating phone number is an important point while validating an HTML form. In this page we have discussed how to validate a phone number (in different format) using JavaScript :
At first, we validate a phone number of 10 digits with no comma, no spaces, no punctuation and there will be no + sign in front the number. Simply the validation will remove all non-digits and permit only phone numbers with 10 digits. Here is the function.
function phonenumber(inputtxt) { var phoneno = /^\d{10}$/; if((inputtxt.value.match(phoneno)) { return true; } else { alert("message"); return false; } }
