单击时将类添加到父 div

如何解决单击时将类添加到父 div

我有一个类似于手风琴的设置，但是是垂直的。我希望将“未设置”类添加到“选择”类中，同时删除“扩展”和“小”类。

我编辑了 jQuery 代码以包含在点击卡片关闭类时，选择删除展开并添加未设置的类，并且如果点击卡片关闭，选择删除小并添加未设置的类。

>

我使用过的任何东西都没有奏效，我认为这是因为 div 位于“选择”部分内。

关于如何让它发挥作用的任何想法？

jQuery(document).ready(function() {

  jQuery(".card-close").on("click",function() {
    jQuery(".choice").removeClass("expand");
    jQuery(".choice").addClass("unset");
    jQuery(".choice").removeClass("small");
    jQuery(".choice").addClass("unset");
  });

  jQuery(".choice").on("click",function() {
    jQuery(".choice").removeClass("expand unset ");
    jQuery(".choice").addClass("small");
    jQuery(this).removeClass("small");
    jQuery(this).addClass("expand");
  });

解决方法

或者你可以在close事件中使用stopPropagation，事件会在触发open之前停止，例如

jQuery(".card-close").on("click",function(event) {
    event.stopPropagation();
    jQuery(".choice").removeClass("expand");
    jQuery(".choice").addClass("unset");
    jQuery(".choice").removeClass("small");
    jQuery(".choice").addClass("unset");
  });

,

使用相对寻址

类似这样的东西 - 全屏运行

$(document).ready(function() {
  $(".card-toggle").on("click",function() {
    const $parent = $(this).closest(".choice")
    $parent.toggleClass("expand");
    $parent.toggleClass("unset");
    $parent.toggleClass("small");
    $parent.toggleClass("unset");
    $(this).text($parent.hasClass("expand") ? "+" : "-")
  });
})
