javascript - 第二 Accordion 面板不更新

标签 javascript jquery html css

在我制作的 Accordion 中，第一个面板是一个图标选择。选择其中一个图标后，它会根据选择的图标将第二个 Accordion 面板替换为三个面板之一。我认为我的问题在于 javascript 以及我如何设置它。我认为我的问题也可能出在类中的 div.panel 类中。

HTML

最佳答案

你需要在 .showing 上设置 max-height 因为 div.panel 有 max-height: 0

var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function() {
    this.classList.toggle("active");
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight) {
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
    }
  };
}
$("#laptop_button").click(function() {
  $('#default_panel').addClass('invisible');
  $('#laptop_panel').removeClass('invisible');
  $('#laptop_panel').addClass('showing');
  $('#tablet_panel').addClass('invisible');
  $('#phone_panel').addClass('invisible');
});
$("#tablet_button").click(function() {
  $('#default_panel').addClass('invisible');
  $("#tablet_panel").removeClass('invisible');
  $('#tablet_panel').addClass('showing');
  $('#laptop_panel').addClass('invisible');
  $('#phone_panel').addClass('invisible');
});
$("#phone_button").click(function() {
  $('#default_panel').addClass('invisible');
  $("#phone_panel").removeClass('invisible');
  $('#phone_panel').addClass('showing');
  $('#laptop_panel').addClass('invisible');
