javascript验证 - Javascript没有运行

Question

我想验证输入，到目前为止我只创建了两条规则。一个用来测试电话号码，另一个用来测试输入的密码是否相同。

我的问题是，由于某种原因，我的JavaScript没有验证输入。我在<script>中引用它，我把它称为onsubmit="return validate()"。出于某种原因，即使使用警报测试来检查其运行，也会失败。所以，我不确定有什么不对，我可以用一些额外的眼睛来做。

function validate() { 
 
    var errMsg = ""; /* stores the error message */ 
 
    var result = true; /* assumes no errors */ 
 
    var phonetest1 = true; 
 
    var phonetest2 = true; 
 

 
    /*get values from the form*/ 
 
    var FirstName = document.getElementById("FirstName").value; 
 
    var Lastname = document.getElementById("Lastname").value; 
 
    var Email = document.getElementById("Email").value; 
 
    var Password = document.getElementById("Password").value; 
 
    var ConPassword = document.getElementById("ConPassword").value; 
 
    var Phone = document.getElementById("Phone").value; 
 

 
    var phonepatt1 = (/\(|0|\d|\)|\d|\d|\d|\d|\d|\d|\d|\d/); 
 
    var phonepatt2 = (/0|\d|\s|\d|\d|\d|\d|\d|\d|\d|\d/); 
 

 
    /* Rule one */ 
 
    if (!phonepatt1.test(Phoneno)) { 
 
    phonetest1 = false; 
 
    } 
 
    if (!phonepatt2.test(Phoneno)) { 
 
    phonetest2 = false; 
 
    } 
 

 
    if (phonetest1 == false && phonetest2 == false) { 
 

 
    errMsg += "Your Phone number is incorrect .\n"; 
 
    result = false; 
 

 
    } 
 
    alert("I'm running"); /* This isn't working */ 
 

 
    /* Rule two */ 
 
    if (ConPassword != Password) { 
 
    errMsg += "Please confirm your password .\n"; 
 
    result = false; 
 
    } 
 

 

 
    if (errMsg != "") { //only display message box if there is something to show 
 
    alert(errMsg); 
 
    } 
 

 
    return result; 
 
}

Answer 1

你在你的JavaScript有wrog名（应该是手机，而不是PHONENO）：

if (!phonepatt1.test(Phone)) { 
    phonetest1 = false; 
} 
if (!phonepatt2.test(Phone)) { 
phonetest2 = false; 
}
