基於Arcgis for javascript實現百度地圖ABCD marker的效果

先給大家看實現後效果：

為直覺期間，先貼出來我做的效果

列表展示和地圖展示以及連動

顯示訊息

實現思路：

1、列表與地圖的互動

滑鼠經過列表時，修改列表圖標，並根據列表返回的值在地圖上繪藍色的marker；滑鼠移出，修改列表圖標為紅色，清空地圖marker圖層。

關鍵程式碼：

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、地圖與清單的互動

滑鼠經過地圖紅色的marker時，修改對應清單圖標，並將紅色 marker的圖片換成藍色的；滑鼠移出，修改對應清單圖標，並修改marker為紅色。

關鍵程式碼：

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、地圖上ABCD的文字是一個單獨的圖層，不參與互動。

4、資料以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。"
