javascript - 如何在html中添加没有输入标签的必选字段

Question

我有这个性别选择器代码，我如何向它添加一个必需的属性，就像它上面的输入文本字段一样。性别的代码没有输入标签添加需要的标签名称和id供php评估。性别数据如何作为正常选择字段发送到下一个处理页面。问题是由一个 2 周大的程序员提出的。

$('.gender-selector .item').on('click', function() {
  $('.gender-selector .item').removeClass('active');
  $(this).addClass('active')

Answer 1

您的代码缺少每个选项的输入。该输入必须是 radio 类型，并且在两者上具有相同的名称和不同的值，如下所示:

<label>
    <input type="radio" required="required" value="boy"> Boy
</label>

<label>
     <input type="radio" required="required" value="girl"> Girl
</label>

您可以将它们放在与 div.circle 相同的位置，并设置它们的样式以使其看起来与它们相同。

如果您想隐藏输入标签，只需这样做，然后在您的 JS 中将所选内容添加到用户点击它们时点击的标签。

请记住，如果输入被隐藏，您将无法在用户不点击它的情况下提交表单，并且用户不会知道为什么表单没有提交，因为您将遇到控制台错误。
