Jquery 单击复选框显示或隐藏内容块

Jquery Show or hide content block on click on checkbox

我点击某个checkbox时有几个复选框,我想显示一些内容(在我的例子中,这是一个简单的块作为例子)当点击另一个复选框时,前一个块应该隐藏和显示一个新块,我认为要解决这个问题你需要应用 forEach 复选框对我有用,但我无法显示块

  <div class="toggle-two">
    <div><small>content 1</small></div>
    <label class="switch-label">
      <input class="switch" id="switch-novice" value="switch-novice"  type="checkbox"/>
       <span class="slider round"></span>
    </label>
  </div>
  
  <div class="toggle-three">
    <div><small>content 2</small></div>
    <label class="switch-label">
      <input class="switch" id="switch-intermediate" value="switch-intermediate"  type="checkbox"/>
      <span class="slider round"></span>
    </label>
  </div>
  
  <div class="toggle-four">
    <div><small>content 3</small></div>
    <label class="switch-label">
      <input class="switch" id="switch-expert" value="switch-expert" type="checkbox" />
      <span class="slider round"></span>
    </label>
  </div>

  <!-- ------------------------------------------- -->
  
  </div>
  <div>
    <div class="content c1"></div>
    <div class="content c2"></div>
    <div class="content c3"></div>
  </div>

**script.js**

let uploadPres = document.getElementsByClassName("content");

$(".content").each(function (index, value) {
  $(`.switch:not([checked])`).on("change", function (param1, param2) {
    $(".switch").not(this).prop("checked", false);

    if ($(".switch").is(":checked")) {
      console.log(this.checked);
    }
  });
});

最初 class 命名的内容默认有 display: none

您还可以看到this example in codesandbox

在每个输入复选框上添加关联内容的引用 div,如下所示。

<input class="switch" id="switch-novice" value="switch-novice"  type="checkbox" data-content="c1"/>
 OR
<input class="switch" id="switch-novice" value="switch-novice"  type="checkbox" data-content="c2"/>

现在只需像下面这样更新您的代码。

$(`.switch`).on("change", function (a, b) {
  $(".switch").not(this).prop("checked", false);

  if ($(".switch").is(":checked")) {
    var contentToOpen = $(this).data("content"); // read the associated class of the div

    $(`.content`).hide(); // hide all existing opened ones
    $(`.${contentToOpen}`).show(); // show the associated one
  }
});

function toggle(event){
  var container = event.target.closest(".togglers");
  var currentContainer = event.target.closest(".toggle");
  var index = Array.from(container.children).indexOf(currentContainer);
  
  var checkboxes = document.querySelectorAll(".toggle input");
  $(checkboxes).prop("checked",false);
  $(event.target).prop("checked", true);

  var contentItems = document.querySelectorAll(".content-items .content");
  $(contentItems).hide();
  var content = contentItems[index];
  $(content).slideToggle();
}
.content {
  display: none;
}
