            }
            buttonAddEventListener.addEventListener("click", function(){
                alert("1");
            })
            buttonAddEventListener.addEventListener("click", function(){
                alert("2");
            })
            buttonAddEventListener.addEventListener("click", function(){
                alert("3");
            })
    </script>

addEventListener可以绑定多个，onclick只有最后一个有效果
