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

先給大家展示實現後效果：

為直觀期間，先貼出來我做的效果

列表展示和地圖展示以及聯動

顯示資訊

實現思路：

1、列表與地圖的互動

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

關鍵代碼：

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、地圖與列表的互動

滑鼠經過地圖紅色的marker時，修改對應列表表徵圖，並將紅色 marker的圖片換成藍色的；滑鼠移出，修改對應列表表徵圖，並修改marker為紅色。

關鍵代碼：

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":"拉薩", "x":91.162998, "y":29.71042,  "desc":"拉薩是中國西藏自治區的首府，西藏的政治、經濟、文化和宗教中心，也是藏傳佛教聖地。"  },  {  "id":"B", "name":"西寧","x":101.797303,"y":36.593642,  "desc":"西寧是青海省的省會，古稱西平郡、青唐城，取”西陲安寧“之意，是整個青藏高原最大的城市。"  },  {  "id":"C","name":"蘭州","x":103.584297,"y":36.119086,  "desc":"蘭州，甘肅省省會，西北地區重要的工業基地和綜合交通樞紐，西部地區重要的中心城市之一，絲綢之路經濟帶的重要節點城市。"  },  {  "id":"D","name":"成都","x":104.035508,"y":30.714179,  "desc":"成都，簡稱蓉，四川省省會，1993年被國務院確定為西南地區的科技、商貿、金融中心和交通、通訊樞紐。"  } ];
