Question

我已经阅读了论坛和教程，但是我是jQuery和JS的初学者。我想在我的页面上有多个切换器，这些切换器在div之外具有显示/隐藏内容，但我无法实现。我最接近的是拥有它们，但是它们都可以一次打开和关闭。

我正在尝试实现以下效果：如果您单击“更多内容指示器”，它将消失，并且将显示隐藏的内容，而在隐藏的内容（现在可见）的末尾将是另一个“隐藏”按钮。

请查看代码，

Answer 1

通过两次调用我固定的$("button").click(...)，为每个按钮提供了两个处理程序。

我做了一些进一步的清理工作，以更好地了解正在发生的事情，然后将其缩小以使其更适合SO。

（此外，有很多CSS出现两次，我建议您只保留其中一半，除非您确实打算将其制作成两种不同的样式。）

$(document).ready(function() {

  // Use $("#id") instead of $("button")
  $("#switcher0").click(function() {
    $("#toggler0").toggle(800);
    $('#switcher0').toggleClass('showed0 hidden0');
  });

  $("#hide0").click(function() {
    $("#toggler0").hide(800);
    $('#switcher0').toggleClass('showed0 hidden0');
  });

  // Use $("#id") instead of $("button")
  $("#switcher1").click(function() {
    $("#toggler1").toggle(800);
    $('#switcher1').toggleClass('showed1 hidden1');
  });

  $("#hide1").click(function() {
    $("#toggler1").hide(800);
    $('#switcher1').toggleClass('showed1 hidden1');
  });

});

.wrapper {
  max-width: 740px;
  margin: auto;
}

.hidden0 {
  display: none;
}

.showed0 {
  display: block;
}

#switcher0 {
  background: #fff;
  font-size: 50px;
  border-style: none;
  margin: auto;
  cursor: pointer;
}

.hidden1 {
  display: none;
}

.showed1 {
  display: block;
}

#switcher1 {
  background: #fff;
  font-size: 50px;
  border-style: none;
  margin: auto;
  cursor: pointer;
}

#hide0 {
  margin: 20px auto;
  display: block;
  cursor: pointer;
  background: #fff;
  font-size: 50px;
  border-style: none;
}

#hide1 {
  margin: 20px auto;
  display: block;
  cursor: pointer;
  background: #fff;
  font-size: 50px;
  border-style: none;
}
