对于用户名，验证代码有效，但对于电话验证它不起作用，我想要电话验证空字段检查和格式检查以及电子邮件检查.帮助我，因为我是 JavaScript 的新手

试试这段代码。 

function formValidation()
    {
    var phone=document.forms["registration"]["phone"].value;
    var phone_num = /^'d{10}$/;  
        if (phone=="")
        {
            alert("enter your phone number");
            return false;
        }
        else if(phone) 
        {
            if(!phone_num.test(phone)) 
        {  
         alert("Not a valid Phone Number");  
         return false;
        }
        }
        var email = document.forms["registration"]["email"].value;
        if (email=="")
            {
                alert("enter your email id");
                return false;
            }
        var atpos = email.indexOf("@");
        var dotpos = email.lastIndexOf(".");
        if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length)
        {
            alert("Not a valid e-mail address");
            return false;
        }
    }

您的手机功能中有一个额外的typo (：

尝试：

if(inputtxt.value.match(phoneno))

而不是if((inputtxt.value.match(phoneno))

PS:提示在使用JS时查看和使用控制台工具
