关于如何用Jquery监听鼠标滚轮改变横向滚动条

$(function(){
       
    if ((navigator.userAgent.indexOf('MSIE') >= 0)){/*判断是否是IE浏览器*/
        var scroll_width = 100;
        $("html").on("mousewheel", function(e){
            var delta = e.originalEvent.wheelDelta;
            if(delta<0){
                $("html").scrollLeft($("html").scrollLeft() + scroll_width);
            }
            else{
                $("html").scrollLeft($("html").scrollLeft() - scroll_width);
            }
        });
    }else{
        var scroll_width = 100;
        var scroll_events = "mousewheel DOMMouseScroll MozMousePixelScroll";
        $("body").on(scroll_events, function(e){
            var delta = e.originalEvent.wheelDelta
            console.log(delta);
            var detail= e.originalEvent.detail;
            if(!detail){/*谷歌浏览器*/
                this.scrollLeft-= (delta);
            }else{/*火狐浏览器*/
                if(detail>0){
                    $("html").scrollLeft($("html").scrollLeft() + scroll_width);
                }
                else{
                    $("html").scrollLeft($("html").scrollLeft() - scroll_width);
                }
            }
        });
    }

})

 下面是监听鼠标左右键事件

$(document).ready(function(){

     $(window).mousedown(function(event){

     if(event.button==0){

     alert("你点击了左键");

     }else{

     alert("你点击了右键");

     }

     });

     });
