实际上，我在所有这些输入字段中都使用了 required 属性，因为它们是强制性的。实际上我正在使用条件选择选项，如果用户选择是，则出现一个强制输入字段，用户必须填写，在这种情况下，我的提交按钮工作，我移至下一页但是当用户选择否并且没有强制字段出现，在这种情况下，当我单击提交按钮时，它不起作用。我该如何解决这个问题？我正在使用 jquery。

$(document).ready(function() {
  Orientation();
  $("#to_check_recognition").change(function() {
    Orientation();
  });
});

function Orientation() {
  if ($("#to_check_recognition").val() == 'yes')
    $("#Average_orientation").show();
  else
    $("#Average_orientation").hide();
}

问题在于，尽管该字段是隐藏的，但它仍然具有required设置的属性。因此无法提交表单。要解决此问题，您需要在显示/隐藏字段时添加/删除该属性。

另请注意，您的 JS 代码不应随意放置在table元素的中间。将其放在<head>或 之前</body>。

最后，不要使用 和 等内联事件onclick属性onsubmit。改为使用不显眼的事件处理程序。同样，不要将您的 CSS 内联在 HTML 中。它应该从单独的样式表中应用。

说了这么多，试试这个：

$(document).ready(function() {
  Orientation();

  $("#to_check_recognition").change(function() {
    Orientation();
  });

  $('form').on('submit', function(e) {
    console.log('form submitting...');
    if (!ValidateForm(this)) {
      e.preventDefault();
    }
  });
});

function Orientation() {
  var averageReqd = $("#to_check_recognition").val() === 'yes';
  $("#Average_orientation").toggle(averageReqd);
  $('input[name="Average_orientation"]').prop('required', averageReqd);
}

function ValidateForm() {
  // noop
}
form {
  width: 1200px;
  margin: 0px auto;
}

table {
  margin: 0px 40px;
}

table td {
  width: 50%;
}

#to_check_recognition {
  width: 350px;
  height: 35px;
  border-radius: 8px;
}

#Average_orientation {
  display: none;
}

span,
span {
  color: red;
}

#Average_orientation input {
  width: 350px;
  height: 25px;
  border-radius: 8px;
}

td.foo {
  text-align: right;
  height: 225px;
}

td.foo input {
  width: 200px;
  height: 50px;
  border-radius: 12px;
  color: blue;
  background: gold;
  cursor: pointer;
}
