我的html页面上的小脚本有问题.它只是一个函数，应该由标记中的onclick方法调用.它不起作用.每次我在浏览器中单击链接时，控制台都会显示"ReferenceError:未定义$"，并指向以下代码的第三行.

    function del(urlToDelete) {
        $.ajax({
            url: urlToDelete,
            type: 'DELETE',
            success: function(results) {
                location.reload();
            }
        });
    }
</script>
