如何验证具有多个选项卡的表单？

Question

所以我有一个包含三个标签的注册表单。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，例如地址、手机号码、状态等，第三个选项卡是用户必须同意条款和条件的地方并提供数字签名。

我可以打开任一选项卡，但是我喜欢不填写某些字段，但是当我单击注册按钮（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键入并且密码/确认密码匹配。例如，任何未显示的字段都应通知用户。

代码：

            <h5 class="text-center bujishu-gold form-card-title">Registration</h5>

我尝试在输入上使用required，但似乎没有做任何事情。在我看来，jQuery 似乎是唯一剩下的选择，但我想知道有没有更简单的方法来实现这一点？

Answer 1

我正在使用手机，因此您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，当你切换标签时，你实际上只是让一些隐藏的元素显示，一些元素隐藏在同一个表单中。这在 JavaScript 中很容易做到。然后你可以将它们全部设置为 required 和 tada。不是 100% 确定这是否有效，但我认为它会。确保使用 html hidden 属性而不是 css display none。

Answer 2

这是一个使用 JQuery 验证密码匹配的示例。
我正在使用.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 标签的值，如果它们不匹配，我将返回一条带有红色和 bg 的错误消息给不匹配的用户警告，我是还禁用了提交按钮，因此他们在解决问题之前无法提交表单。然后，如果有匹配项，我将返回一条带有绿色和 bg 的成功消息，并删除 disabled 属性以便可以提交表单。

重要提示： 对数据库或登录的验证表单应在后端完成，而不是在前端完成。前端应仅用作验证的第一步。请记住，可以禁用 JS 并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");
    }
  });
