请教一下，这代码应该没写错吧，怎么运行不出来了呀

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>title</title>
    <script type="text/javascript">
        function test(){
            alert("hello");
        }
    </script>
</head>
<body>
<script type="text/javascript">
    <a href="javascript:test()">点击</a>
</script>
</body>
</html>

//浏览器报错：Uncaught SyntaxError: Unexpected token '<'


<!DOCTYPE html>
<html lang="en">

    <script type="text/javascript">
        function test(){
            alert("hello");
        }
    </script>
</head>
<body>
    <a href="javascript:test()">点击</a>

</body>
</html>
 
//浏览器报错：Uncaught SyntaxError: Unexpected token '<'

你把html写进了script 中，所以script 报错。


 <a href="javascript:test()">点击</a>

这个放到body里放script里当然报错
