使用jquery展开其他托盘时折叠托盘

jquery html javascript

Code Guy · 技术社区 · 4 年前

当当前托盘展开时,我需要折叠所有其他托盘,并向用户通知展开托盘的类名(无论content2、content1、content2当前是否展开并处于活动状态,当全部关闭时,返回null)。它们在装载时都需要关闭。我不明白怎么做。

active 或不依赖于此隐藏或显示div并打印结果,即:classes或null。

$("div[class*=content]").toggle()
$(".collapsible").click(function() {
  //remove active from other collaps.. button
  $(".collapsible").not(this).removeClass("active")
  //check if the button which is click have class active
  if ($(this).hasClass("active")) {
    $(this).removeClass("active") //remove active class
    console.log("Null...") //means no one is slected
  } else {
    $(this).addClass("active") //add class active
    $(".collapsible").not(this).next("div").hide() //hide next div from others
    console.log("Current Active " + $(this).next("div").attr("class"))
  }
  $(this).next("div").toggle() //show div or hide
})

.collapsible {
  background-color: #777;
  color: white;
  cursor: pointer;
  padding: 18px;
  width: 100%;
  border: none;
  text-align: left;
  outline: none;
  font-size: 15px;

先把你的一切藏起来 div 使用通配符。单击按钮时显示您的 部门 使用 next 就像下面一样。

$("[class^=content]").hide();
$('.collapsible').click(function(e) {
  $("[class^=content]").hide();
  $(this).next('div').show();
});

.collapsible {
  background-color: #777;
  color: white;
  cursor: pointer;
  padding: 18px;
  width: 100%;
  border: none;
  text-align: left;
  outline: none;
  font-size: 15px;
}

.active,
.collapsible:hover {
  background-color: #555;
}

.content {
  padding: 0 18px;
  display: none;
  overflow: hidden;
  background-color: #f1f1f1;
}
