Javascript滚动到div id

Pro*_*Pus 12 html javascript css jquery

我在谷歌上搜索了我的问题的解决方案,我无法理解为什么我写的代码对所有人都有效,但对我来说却没有.

我写过:

<head>
    <meta charset="utf-8" />
    <title></title>
    <script type="text/javascript">
        function scrollTo() {
            $('html, body').animate({ scrollTop: $('#div_id').offset().top }, 'slow');
            return false;
        }
    </script>
    <style type="text/css">
        .uno {
            height: 1000px;
            background: #808080;
        }
        .due {
            margin-top: 300px;
            height: 500px;
            background: #ff00ff;
        }
    </style>
</head>
<body>
    <div class="uno" onclick="scrollTo()"> 
        Clicca
    </div>
    <div class="due" id="div_id"></div>
</body>
