需要手機驗證10位數字，空格和連字符

Question

我環顧四周，看到了很多正則表達式的例子，但沒有一個我正在尋找。我需要驗證10位數字，允許空格和破折號，但不包括括號或其他字符。

以下是我目前使用：

function validatePhone(phone) { 
    var error = ""; 
    var stripped = phone.value.replace(/^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/, ''); 

    if (phone.value == "") { 
     document.getElementById('phone-error').innerHTML = "Please enter a phone number"; 
     phone.style.background = 'Yellow'; 
     var error = '6'; 
    } else if (isNaN(parseInt(stripped))) { 
     var error = "5"; 
     document.getElementById('phone-error').innerHTML = "The phone number contains illegal characters."; 
     phone.style.background = 'Yellow'; 
    } else if (stripped.length < 10) { 
     var error = "6"; 
     document.getElementById('phone-error').innerHTML = "The phone number is too short."; 
     phone.style.background = 'Yellow'; 
    } else { 
     phone.style.background = 'White'; 
     document.getElementById('phone-error').innerHTML = ''; 
    } 

謝謝！

Answer 1

你可以用空白空間替換\D ...所以你只剩下數字了。

這是我會怎麼做：

function validatePhone(phone) { 
    var error = ""; 
    var stripped = phone.value.replace(/\D+/, ''); // strips all non digit characters 

    if (stripped == "") { 
     document.getElementById('phone-error').innerHTML = "Please enter a phone number"; 
     phone.style.background = 'Yellow'; 
     error = '6'; 
    } else if (phone.value.match(/[^\d() .-]/)) { 
     error = "5"; 
     document.getElementById('phone-error').innerHTML = "The phone number contains illegal characters."; 
     phone.style.background = 'Yellow'; 
    } else if (stripped.length < 10) { 
     error = "6"; 
     document.getElementById('phone-error').innerHTML = "The phone number is too short."; 
     phone.style.background = 'Yellow'; 
    } else { 
     phone.style.background = 'White'; 
     document.getElementById('phone-error').innerHTML = ''; 
    } 
}
