我试图在youtube上复制一个视频，虽然这样做的功能incdec（）没有被调用..我尝试了一切，但似乎没有任何工作

Answer 1

有一个语法错误，它是function incdec(plusminus)。将其更改为An unknown error has occurred. Message:org.springframework.dao.EmptyResultDataAccessException: No entity found for query No entity found for query.。


    <script>
        function incdec(plusminus){
            alert('running');
            plusminus = parseInt(plusminus);
            currentlife = document.getElementById("life").innerHTML + plusminus;
            document.getElementById("life").innerHTML = currentlife;
        }
    </script>
