Js实现鼠标滚轮滑动监听

监听鼠标滚动行为

windowAddMouseWheel();
function windowAddMouseWheel() {
    var scrollFunc = function (e) {
        e = e || window.event;
        if (e.wheelDelta) {  //判断浏览器IE，谷歌滑轮事件
            if (e.wheelDelta > 0) { //当滑轮向上滚动时
                alert("滑轮向上滚动");
            }
            if (e.wheelDelta < 0) { //当滑轮向下滚动时
                alert("滑轮向下滚动");
            }
        } else if (e.detail) {  //Firefox滑轮事件
            if (e.detail> 0) { //当滑轮向上滚动时
                alert("滑轮向上滚动");
            }
            if (e.detail< 0) { //当滑轮向下滚动时
                alert("滑轮向下滚动");
            }
        }
    };
    //给页面绑定滑轮滚动事件
    if (document.addEventListener) {
        document.addEventListener('DOMMouseScroll', scrollFunc, false);
    }
//滚动滑轮触发scrollFunc方法
    window.onmousewheel = document.onmousewheel = scrollFunc;
}

禁止、启用鼠标滚动行为

function disabledMouseWheel() {
    var div = document.getElementById('divid');
    if (div.addEventListener) {
        div.addEventListener('DOMMouseScroll', scrollFunc, false);
    }//W3C
    div.onmousewheel = div.onmousewheel = scrollFunc;//IE/Opera/Chrome
}
  
function scrollFunc(evt) {
    evt = evt || window.event;
    if (evt.preventDefault) {
        // Firefox
        evt.preventDefault();
        evt.stopPropagation();
    } else {
        // IE
        evt.cancelBubble = true;
        evt.returnValue = false;
    }
    return false;
}
  
window.onload = disabledMouseWheel;
