Bootstrap手风琴菜单不起作用

Question

我设计了一个像图像中的手风琴菜单.如果单击菜单,打开的菜单将关闭.这是手风琴的功能.但在这个设计中,我逐个点击菜单,但前一个没有关闭..如何解决这个问题？提前致谢

jQuery(document).ready(function () {
    var acc = document.getElementsByClassName("accordion");
    var i;
    for (i = 0; i < acc.length; i++) {
        acc[i].onclick = function () {
            this.classList.toggle("active");
            this.nextElementSibling.classList.toggle("show");
        };
    }
    
});

Answer 1

请看一下这个jQuery方法:

if (!$(this).hasClass("active")) {
     var oldAcc = $(".accordion.active");
     oldAcc.toggleClass("active");
     oldAcc.next().toggleClass("show");
}

通过上面的代码,我们可以参考已经打开的手风琴并在打开另一个之前关闭它.

jQuery(document).ready(function() {

  $(".accordion").click(function() {
    if (!$(this).hasClass("active")) {
      var oldAcc = $(".accordion.active");
      oldAcc.toggleClass("active");
      oldAcc.next().toggleClass("show");
    }
    $(this).toggleClass("active");
    $(this).next().toggleClass("show");


  });

});
