我有这个验证电话号码的代码：

function phvalid() {
    var regexObj = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;
    if (regexObj.test(subjectString)) {
        var formattedPhoneNumber = subjectString.replace(regexObj, "($1) $2-$3");
    } else {
        alert("Invalid Number");
    }
}

我正在尝试将其验证到以下 html 代码的正文中：

<p class="normal">Phone:
    <input type='text' id='ph' />
    <input type='button' onclick="phvalid();" value="Click" />
</p>

这个功能是对的还是我做错了什么？

你从不定义subjectString

试试这个：http: //jsfiddle.net/bfvXL/1/

function phvalid() {

    var regexObj = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;
    var subjectString = document.getElementById("ph").value;
    if (regexObj.test(subjectString))

    {
        var formattedPhoneNumber = subjectString.replace(regexObj, "($1) $2-$3");
    } else {
        alert("Invalid Number");
    }

}

这将运行您的功能，但我不确定您对该formattedPhoneNumber块的意图是什么。

此外，您需要确保您的 onclick 可以访问它。所以你必须把你的 js 放在你的 body 中，或者放在 dom 加载后运行的块中。

编辑：我相信这就是你想要的：http formattedPhoneNumber: //jsfiddle.net/bfvXL/2/

Edit2：对于下面评论中的新要求......试试这个：http: //jsfiddle.net/bfvXL/3/

function phvalid() {
    var subjectString = document.getElementById("ph").value;
    subjectString = subjectString.replace(/[^\d]/g, "");
    if (subjectString.length == 10) {
        var regexObj = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;
        var formattedPhoneNumber = subjectString.replace(regexObj, "($1) $2-$3");
        document.getElementById("ph").value = formattedPhoneNumber;
    } else {
        alert("Invalid Number");
    }
}

实际上，由于regexObj在这种情况下没有用于验证，您可以简单地将其作为/(\d{3})(\d{3})(\d{4})/

看到非常通用的电话号码 - 传真号码验证码 - 希望它会有用 http://oracleadf-java.blogspot.in/2013/05/phone-number-custom-validation-in-adf.html
