先给大家展示实现后效果：
为直观期间，先贴出来我做的效果
列表展示和地图展示以及联动
显示信息
实现思路：
1、列表与地图的互动
鼠标经过列表时，修改列表图标，并根据列表返回的值在地图上绘蓝色的marker；鼠标移出，修改列表图标为红色，清空地图marker图层。
关键代码：
title.on("mouseover",function(){ var attr = $(this).data("attr"); $("#icon"+attr.id).css("background","url('images/blue.png')"); var pt=new Point(attr.x,attr.y,{"wkid":4326}); var pms = new esri.symbol.PictureMarkerSymbol("images/blue.png",24,26) var gImg = new Graphic(pt,pms); gLyrHover.add(gImg); }); title.on("mouseout",function(){ var attr = $(this).data("attr"); $("#icon"+attr.id).css("background","url('images/red.png')"); gLyrHover.clear(); });
2、地图与列表的互动
鼠标经过地图红色的marker时，修改对应列表图标，并将红色 marker的图片换成蓝色的；鼠标移出，修改对应列表图标，并修改marker为红色。
关键代码：
gLyr.on("mouse-over",function(e){ map.setMapCursor("pointer"); var sms = e.graphic.symbol; sms.url = "images/blue.png"; gLyr.redraw(); $("#icon"+e.graphic.attributes.id).css("background","url('images/blue.png')"); }); gLyr.on("mouse-out",function(e){ map.setMapCursor("default"); var sms = e.graphic.symbol; sms.url = "images/red.png"; gLyr.redraw(); $("#icon"+e.graphic.attributes.id).css("background","url('images/red.png')"); });
3、地图上ABCD的文字是一个单独的图层，不参与互动。
4、数据以JSON形式存在。
var data = [ { "id":"A","name":"拉萨", "x":91.162998, "y":29.71042, "desc":"拉萨是中国西藏自治区的首府，西藏的政治、经济、文化和宗教中心，也是藏传佛教圣地。" }, { "id":"B", "name":"西宁","x":101.797303,"y":36.593642, "desc":"西宁是青海省的省会，古称西平郡、青唐城，取”西陲安宁“之意，是整个青藏高原最大的城市。" }, { "id":"C","name":"兰州","x":103.584297,"y":36.119086, "desc":"兰州，甘肃省省会，西北地区重要的工业基地和综合交通枢纽，西部地区重要的中心城市之一，丝绸之路经济带的重要节点城市。" }, { "id":"D","name":"成都","x":104.035508,"y":30.714179, "desc":"成都，简称蓉，四川省省会，1993年被国务院确定为西南地区的科技、商贸、金融中心和交通、通讯枢纽。" } ];
