假如使用的是jquery的话，则直接使用jQuery的e.pageX和e.pageY则行，里面已经封装好了。

最近的一个项目用到了这个JS，需要判断鼠标光标是否移入了某个块的区域，当进入时，则停止循环滚动，当出来时，则继续滚动

//两秒后调用var dteamPos = $(".dteam-con-pos");var dteamList = $("#dteamList");function AutoScroll(){ //循环向左滚动var _scroll = $("#firstDteam > ul");//ul往左边移动200px_scroll.filter(':not(:animated)').animate({marginLeft:"-200px"},1000,function(){//把第一个li丢最后面去_scroll.css({marginLeft:0}).find("li:first").appendTo(_scroll);});var _scroll2 = $("#secondDteam > ul");//ul往左边移动200px_scroll2.filter(':not(:animated)').animate({marginLeft:"-200px"},1000,function(){//把第一个li丢最后面去_scroll2.css({marginLeft:0}).find("li:first").appendTo(_scroll2);});var _scroll3 = $("#thirdDteam > ul");//ul往左边移动200px_scroll3.filter(':not(:animated)').animate({marginLeft:"-200px"},1000,function(){//把第一个li丢最后面去_scroll3.css({marginLeft:0}).find("li:first").appendTo(_scroll3);});}var flag = 1;var _scrolling;if(flag == 1){_scrolling=setInterval(AutoScroll,2000);}var index;$(".dteam-con").mouseover(function(e){// e.stopPropagation();var x = 10;var y = 10;var self = $(this);var _html = self.html();dteamPos.html('');dteamPos.html(_html);if(dteamPos.html() != ''){clearInterval(_scrolling);}var dteamLeft = self.offset().left - x;var dteamTop = self.offset().top - y;dteamPos.css({top:dteamTop,left:dteamLeft,display:"block"})});var dteamList = $('#dteamList"), dteamPost = $(".dteamPos"), dteamListTop, dteamlistHeight, dteamlistBottom;function resetPos(evt){dteamListTop = dteamList.offset().top;dteamlistHeight = dteamList.height();dteamlistBottom = parseInt(dteamListTop + dteamlistHeight);if((evt.pageY <dteamListTop) || (evt.pageY > dteamlistBottom)){if(dteamPos.html() != ''){dteamPos.html('');dteamPos.hide();_scrolling=setInterval(AutoScroll,2000);}}}$(document).mousemove(function(e){// e.stopPropagation();resetPos(e);});$(window).on("resize",function(e){resetPos(e);})

代码各种复杂
