json对象为啥访问不了?


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>JSON</title>
</head>
<body>
    <script type="javascript">
      //创建json对象
      var studentObj = {
        "sno" :"110",
        "sname":"张三",
        "sex":"男"
      };
      //访问json属性
      alert(studentObj.sno + "," +studentObj.sname + "," +studentObj.sex);
    </script>
</body>
</html>

小伙子竟然偷懒，script type写错了

<script type="text/javascript">
      var studentObj = {
        "sno" :"110",
        "sname":"张三",
        "sex":"男"
      };
      alert(studentObj.sno + "," +studentObj.sname + "," +studentObj.sex);
    </script>
