如何使用多个选项卡验证表单

Question

所以我有一个带有三个选项卡的注册表单。第一个选项卡是用户可以输入email、password和confirm password的地方，第二个选项卡是他们的详细信息，如地址、手机号码、状态等，第三个选项卡是必须同意T&C并提供数字签名。

我可以随意打开任何一个选项卡，而无需填写某些字段，但当我单击注册按钮(在第三个选项卡中(时，它应该执行客户端验证，以确保所有字段都已输入，并且密码/确认密码匹配。例如，任何未显示的字段都应通知用户。

代码：

<div>
<div class="card border-rounded-0 bg-bujishu-gold guests-card">
<h5 class="text-center bujishu-gold form-card-title">Registration</h5>
<ul class="nav nav-tabs nav-fill" role="tablist">

我尝试在输入上使用required，但似乎什么都没做。在我看来，jQuery似乎是唯一剩下的选项，但我想知道有没有更简单的方法可以实现这一点？

Answer 1

我在手机上，所以你的代码基本上是不可读的，因为手机格式很奇怪。你可以做的是，当你切换选项卡时，你实际上只是让一些隐藏的元素显示出来，而一些元素隐藏在同一个表单中。这在JavaScript中很容易做到。然后您可以将它们全部设置为required和tada。不是100%确定这是否有效，但我认为会的。请确保使用html隐藏属性，而不是css显示none。

Answer 2

以下是使用JQuery验证匹配密码的示例
我正在用.keyup(function(){})设置一个函数，然后我正在设置一个条件来检查每个id标记的值，如果它们不匹配，我将向用户返回一条带有红色和bg的错误消息，警告不匹配，并且我还禁用了提交按钮，这样他们在解决问题之前就无法提交表单。然后，如果有匹配，我将返回一条带有绿色和bg的成功消息，并删除禁用的属性，以便提交表单。

重要提示：数据库或登录的验证表单应该在后端完成，而不是在前端。前端只能作为验证的第一步。请记住，JS可能会被禁用，从而使您的验证变得毫无价值。使用PHP或ASP进行最终验证！

$("#password").keyup(function() { // we fire on the keyup event
//compare the values of the two passwords using .val() and their ids        
if ($("#password").val() != $("#confirm_password").val()) {  
// if they do not match we add an error message to the div #msg
// we also remove potential latent classes and add new class to get warning font color and bg color
$("#msg").html("Passwords do not match").removeClass("alert-success").addClass("alert alert-danger");
// disable and style the submit button using .prop() and remove/addClass()
$("#enter").prop('disabled', true);
$("#enter").removeClass("alert-success").addClass("alert alert-danger");
} else {
// On success we add success msg and switch styles to note success in green
$("#msg").html("Passwords matched").removeClass("alert-danger").addClass("alert alert-success");
// Turn the submit back on by removing the disabled attr
$("#enter").prop('disabled', false);
$("#enter").removeClass("alert-danger").addClass("alert alert-success");
}
});
//rinse and repeat for the #confirm-password tag
$("#confirm_password").keyup(function() {
if ($("#password").val() != $("#confirm_password").val()) {
$("#msg").html("Passwords do not match").removeClass("alert-success").addClass("alert alert-danger");
$("#enter").prop('disabled', true);
$("#enter").removeClass("alert-success").addClass("alert alert-danger");
} else {
$("#msg").html("Passwords matched").removeClass("alert-danger").addClass("alert alert-success");
$("#enter").prop('disabled', false);
$("#enter").removeClass("alert-danger").addClass("alert alert-success");
}
});
