Question

我环顾四周，看到了许多正则表达式的例子，但不是我正在寻找的。我需要验证10位数，允许空格和破折号，但不能括号或其他字符。

以下是我目前正在使用的内容：

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 = '';
    }

谢谢！

这就是我要做的事情：

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 = '';
    }
}

你可以用空格替换\D ......这样你只剩下数字了。
