汉堡菜单不起作用

Question

我正在尝试了解汉堡菜单的工作原理。它不工作。我尝试添加 'ready function' 也没有任何变化。我在html中用脚本标签写js代码，我应该单独提到js代码吗？

<script>
$( document ).ready(function() {
$( ".cross" ).hide();
$( ".menu" ).hide();
$( ".hamburger" ).click(function() {
$( ".menu" ).slideToggle( "slow", function() {
$( ".hamburger" ).hide();
$( ".cross" ).show();
});
});

$( ".cross" ).click(function() {
$( ".menu" ).slideToggle( "slow", function() {
$( ".cross" ).hide();
$( ".hamburger" ).show();
});
});

});

</script>

body{
  font-family: 'Noto Sans', sans-serif;
 margin:0;
  background-image: url('https://unsplash.imgix.net/41/yEWFnFQRqfmY9l9efJ6g_Snap01-web.jpg?q=75&w=1080&h=1080&fit=max&fm=jpg&auto=format&s=7580de2dc3b3821f0dc1c97f2d60fe7c');

Answer 1

您应该将 jQuery 导入您的页眉。

<head>
    <title>Hello</title>
    <link type="text/css" rel="stylesheet" href="new9.css"/>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
</head>
