Question

我正在尝试在我的页面中使用DataTables，出于某种原因，我在浏览器中查看错误时收到“JQuery is undefined”错误。这是我的HTML代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<script type="text/javascript" charset="utf-8" src="/CensusDatabase/js/jquery.dataTables-1.9.4.min.js" ></script>
<script type="text/javascript" src="/CensusDatabase/js/DrawTable.js" ></script>

<head>
    <title>My Census Data</title>
    <style type="text/css">
        body {
            color: black;
            background-color: #ffaacc;
            font-family: "Trebuchet MS", "Calibri", sans-serif 
        }
        h1 {
            font-family: "Trebuchet MS", "Calibri", sans-serif
        }

   </style>

</head>

<body>

    <h1>My Census Data</h1>

    <div class="census">

        <div id="block-system-main">
            <h2>Reports</h2>
                <ul>
                    <li><a href="#" onclick="nationalAgeGender()">National age and gender data</a></li>
                    <li><a href="#" onclick="arizonaAgeGender()">Arizona age and gender data</a></li>
                    <li><a href="#" onclick="combinedAgeGender()">Combined age and gender data</a></li>
                    <li><a href="#" onclick="nationalRace()">National race data</a></li>
                    <li><a href="#" onclick="arizonaRace()">Arizona race data</a></li> 
                    <li><a href="#" onclick="combinedRace()">Combined race data</a></li>
                </ul>
        <div id="reportsData"><i>Please select a list to display.</i></div>
    </div>
  </div>

这是我的JavaScript代码：

有谁知道这里有什么问题？

好像你没有包含jQuery库：

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
