Answer 1

name attribute 存在于与 Web 请求关联的表单输入元素中（换句话说，当数据识别在服务器端完成时），主要是表单元素。

您可以使用 id 属性（在当前文档中应该是 uniq）来识别特定的 div 元素，如果逻辑涉及多个元素，则可以使用类。

以下是实施建议：

$(function() {
      // Cache references to both radio inputs at the top of the DOM-ready
      // event handler making further logic clearer
      let $nameInput = $('input#update-name')
          , $descInput = $('input#update-description')
      ;

      // Attach a single click event handler to both former radio inputs.
      // Depending on which radio button is clicked, the associated content
      // will be shown whereas the content associated to the other radio
      // button will be hidden
      $nameInput.add($descInput).on('click', function() {
          let isName = this === $nameInput[0]
              , $show = isName ? $('#nama-div') : $('#deskripsi-div')
              , $hide = isName ? $('#deskripsi-div') : $('#nama-div')
          ;

          if (this.checked) {
              $show.fadeIn();
              $hide.hide();
          }
      });
  });

/** Set initial _display_ state of both content div as a CSS rule **/
div#nama-div, div#deskripsi-div {display: none}

您需要将class 或id 属性赋予div，您不能将name 属性用于div，在您的情况下为nama 和deskripsi。在下面的代码中，我为divs 都提供了class 属性，您想隐藏特定单选按钮的点击：

$(function() {
        $('.nama').hide();

        //show it when the checkbox is clicked
        $('input[id="update-name"]').on('click', function() {
            if ($(this).prop('checked')) {
              //show div with class="nama"
                $('.nama').fadeIn();
                 //hide other div
                 $('.deskripsi').hide();
            } else if ($('input[id="update-description"]').on('click')) {
              //hide div with class= "nama"
                $('.nama').hide();
            } else {
                $('.nama').hide();
            }

        });

        $('.deskripsi').hide();

        $('input[id="update-description"]').on('click', function() {
            if ($(this).prop('checked')) {
            //show div with class="deskripsi"
                $('.deskripsi').fadeIn();
                //hide other div
                 $('.nama').hide();
            } else if ($('input[id="update-name"]').on('click')) {
                $('.deskripsi').hide();
            } else {
                $('.deskripsi').hide();
            }

        });
    });
