可以把number换成tel
同样是数字，而且默认就没有上下箭头

或者写成这样

<input type="number" onmousewheel="return false;">

if(el.addEventListener){  
    el.addEventListener('DOMMouseScroll',fn,false);  
}//火狐  
el.onmousewheel=fn;
function fn(){
    return false;
    }

<script>
    //给页面绑定滑轮滚动事件
    document.addEventListener('DOMMouseScroll', scrollFunc, false);

    function scrollFunc(event){
        event = event || window.event;
        if (event.wheelDelta) {  //判断浏览器IE，谷歌滑轮事件             
            if (event.wheelDelta > 0) { //当滑轮向上滚动时
                alert("滑轮向上滚动");
            }
            if (event.wheelDelta < 0) { //当滑轮向下滚动时
                alert("滑轮向下滚动");
            }
        } else if (event.detail) {  //Firefox滑轮事件
            if (event.detail> 0) { //当滑轮向上滚动时
                alert("滑轮向上滚动");
            }
            if (event.detail< 0) { //当滑轮向下滚动时
                alert("滑轮向下滚动");
            }
        }
    }

    //滚动滑轮触发scrollFunc方法
    window.onmousewheel = document.onmousewheel = scrollFunc;  
</script>
