我遇到了一个来自JavaScript的平滑滚动函数，如图所示

// Select all links with hashes
$('a[href*="#"]')
  // Remove links that don't actually link to anything
  .not('[href="#"]')
  .not('[href="#0"]')
  .click(function(event) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
      // Does a scroll target exist?
      if (target.length) {
        // Only prevent default if animation is actually gonna happen
        event.preventDefault();
        $('html, body').animate({

          // Must change focus!
          var $target = $(target);
          $target.focus();
          if ($target.is(":focus")) { // Checking if the target was focused
            return false;
          } else {
            $target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
            $target.focus(); // Set focus again

我目前有一个使用HTML和CSS编码的网站。如何在其中实现javascript函数？我试过用谷歌搜索，但答案总是不够具体，因为我在这方面还真是新手

非常感谢您的帮助

对于简单的javascript，只需在html头部添加一个脚本标记即可

<head>
  <title>:D</title>
  ...
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script>
    //your javascript here
  </script>
</head>


：D
...
//你的javascript在这里

当然，有更多的方法可以实现这一点-有关更多信息，它会给出一个错误“uncaughtreferenceerror:$未定义”代码是否有问题？这是因为代码使用jQuery-例如$是jQuery语法-因此您也需要导入jQuery-我更新了我的答案
