电话号码验证

Question

我有这样的代码验证电话号码：

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"); 
    } 
} 

我想验证它到下面的HTML代码的身体：

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

这是功能权限或者我做错了什么？

Answer 1

你从来没有定义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"); 
    } 

} 

这将运行你的函数，但我不知道你的意图是与formattedPhoneNumber块什么。

此外，你需要确保你的onclick可以访问这个。所以你必须把你的js放在你的身体内，或者在dom被加载后运行的块中。

编辑：我相信这是你不想和formattedPhoneNumber什么：http://jsfiddle.net/bfvXL/2/

EDIT2：对于下面的评论新的要求...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在这种情况下未用于验证，因此您可以简单地将其作为/(\d{3})(\d{3})(\d{4})/

看的很普通的电话号码，传真号码验证代码 - 希望这将是有用的 http://oracleadf-java.blogspot.in/2013/05/phone-number-custom-validation-in-adf.html
