单击时将类添加到父级 div

Question

我有一个类似于手风琴但垂直的设置。我想将 class“未设置”添加到“选择”class，同时删除“扩展”和“小”classes。

我编辑了 jQuery 代码以包含当单击卡片关闭 class 时，选择删除展开并添加 class 未设置，以及如果卡片-单击关闭，选择删除小并添加 class 未设置。

虽然我使用过的任何东西都没有用，但我认为这是因为 div 在“选择”部分内。

关于如何让它工作的任何想法？

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");
  });

Answer 2

或者你可以在关闭事件中使用stopPropagation，事件会在触发打开之前停止，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");
  });
