在我的项目中，我正在进行 JS 验证以进行注册。但是电子邮件验证后验证失败。直到电子邮件验证为止，它工作正常。但此后，它不会显示其余验证代码的任何警报。
function signup() {
var signupFullName = $("#signup-full-name");
var signupName = $("#signup-login-name");
var signupEmailAddress = $("#signup-email-address");
var signupPhoneNumber = $("#signup-phone-number");
var signupPassword = $("#signup-password");
var signupConfirmPassword = $("#signup-confirm-password");
var signupAcceptTerms = $("#signup-accept-terms");
if (signupFullName[0].value == "" || signupFullName[0].value == null) {
//alert("Please enter a valid full name.");
alert("Please enter your full name");
signupFullName[0].focus();
return false;
} else if (signupName[0].value == "" || signupName[0].value == null) {
//alert("Please enter a valid login name.");
alert("Please enter your login name.");
signupName[0].focus();
return false;
} else if (signupEmailAddress[0].value == "" || signupEmailAddress[0].value == null) {
//alert("Please enter a valid email address.");
alert("Please enter your email address.");
signupEmailAddress[0].focus();
return false;
}
else if(signupEmailAddress[0].value != "") // problem in this section
{
email=signupEmailAddress[0].value;
if (!(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/).test(email))
{
alert("Please enter a valid email address.");
signupEmailAddress[0].focus();
return false;
}
}
else if (signupPhoneNumber[0].value == "" || signupPhoneNumber[0].value == null) {
// alert("Please enter a valid phone number.");\
alert("Please enter your phone number.");
signupPhoneNumber[0].focus();
return false;
} else if (signupPassword[0].value == "" || signupPassword[0].value == null) {
//alert("Please enter a valid password.");
alert("Please enter your password.");
signupPassword[0].focus();
return false;
} else if (signupConfirmPassword[0].value == "" || signupConfirmPassword[0].value == null) {
alert("Please confirm the password.");
signupConfirmPassword[0].focus();
return false;
} else if (signupPassword[0].value != signupConfirmPassword[0].value) {
//alert("Please confirm the password.");
alert("Password mismatch");
signupConfirmPassword[0].focus();
return false;
} else if ($("#signup-accept-terms")[0].checked == false) {
alert("Please accept the terms and conditions.");
return false;
} else {
alert("Done");
return false;
}
}
HTML 表单代码:
<form name="signup-form" id="signup-form" method="post" action="<?php echo $site_path; ?>/register" class="form-1" onsubmit="signup();return false;">
<p class="field">
<a href="<?php echo $root_path; ?>">

</a>
<h4 style="margin-top:10px;color:#208CCD;">Signup</h4>
<br/>

<p class="field">
<input type="text" name="signup-full-name" id="signup-full-name" placeholder="Full name">

I accept the <a href="#">Terms and Conditions</a> and the <a href="#">Privacy Policies</a>
</input>
</p>
<p class="submit">
<button type="submit" name="submit"><i class="icon-arrow-right icon-large"></i></button>
</p>
</form>
谁能帮我解决这个问题吗？提前致谢。
最佳答案
据我所知，这是因为您使用 if/else 来检查字段的有效性。
因此，代码一次选择一个错误 - 如果有的话。虽然您应该在要验证的所有字段中使用类似 for 循环的东西 我的意思是它选择了这个
} else if(signupEmailAddress[0].value != "") {
但不再陷入内部检查
if (!(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/).test(email))
因为现在电子邮件可以了
