javascript - jQuery div 没有调整大小

Question

我正在尝试在单击时实现 jQuery div 调整大小，但是当我单击 a.dropdown-link div 时没有显示。我没有收到任何错误，但我的代码不起作用。有人可以帮我解决这个问题。这是我的 jQuery 代码：

var dd = $(".dropdown-container");

  $("a.dropdown-link").click(function(e) {
    e.preventDefault();
    e.stopPropagation();
    dd.hide("fast");
    $(this).next().find(".dropdown-container").show("fast");

  });

  $("body").click(function() {
    dd.hide();
  });

  dd.click(function(e) {
    //e.stopPropagation();
  });

还有我的 HTML：

<div id="background" class="website-not-active">

</div>

<!-- wrapper-->
<div id="wrapper">

    <!--here is the left menu-->
    <div id="left-menu" align="center">
    <!-- left logo -->
    <img src="./dashboard/images/logo.png" class="logo"/>

    <img src="./dashboard/images/user.png"/>
    <a href="#"><p>ihg <img src="dashboard/images/arr-down.png" style="padding:3px;"/></p></a>

    <a href="add_hosting.php"><p>add hosting<img src="dashboard/images/arr-down.png" style="padding:3px;"/></p></a>

Answer 1

尝试使用以下 jQuery。它对我有用：

var dd = $(".dropdown-container");

  $("a.dropdown-link").click(function(e) {
    dd.hide("fast");
    $(this).next().find(".dropdown-container").show("fast");
      return false;

  });

  $("body").click(function() {
    dd.hide();
  });

看看这个jfiddle

添加这个

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

在你的脚本之前的头部之后尝试。

Answer 3

你忘了包括 jQuery 吗？添加 jQuery 后，代码在小提琴中工作。
