Uncaught SyntaxError: missing ) after argument list 括号没有少为什么还会报错？


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>jQuery按钮的单击事件</title>
    <script type="text/javascript">
        $(funtion(){
            var $btnobj = $("#btn01");
            $btnobj.click(function () {
                alert("触发单击事件");
            });
        });
    </script>

</head>
<body>
<button id="btn01"> 按钮</button>
</body>
</html>

funtion打错了 是function
