（转）Arcgis for javascript实现百度地图ABCD marker的效果

概述：

在我的博客中，有一篇相关的文章，这段时间，有很多人问我求源码，只是时间过去已长，源代码已找不到，乘着这个9.3放假，又重新实现了下，并相关代码做了优化，在此贴出来，方便大家使用。

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：

 

[javascript] view plain copy
 
 print?
  1. title.on("mouseover",function(){  
  2.     var attr = $(this).data("attr");  
  3.     $("#icon"+attr.id).css("background","url('images/blue.png')");  
  4.     var pt=new Point(attr.x,attr.y,{"wkid":4326});  
  5.     var pms = new esri.symbol.PictureMarkerSymbol("images/blue.png",24,26)  
  6.     var gImg = new Graphic(pt,pms);  
  7.     gLyrHover.add(gImg);  
  8. });  
  9. title.on("mouseout",function(){  
  10.     var attr = $(this).data("attr");  
  11.     $("#icon"+attr.id).css("background","url('images/red.png')");  
  12.     gLyrHover.clear();  
  13. });  
 


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：

 

[javascript] view plain copy
 
 print?
  1. gLyr.on("mouse-over",function(e){  
  2.     map.setMapCursor("pointer");  
  3.     var sms = e.graphic.symbol;  
  4.     sms.url = "images/blue.png";  
  5.     gLyr.redraw();  
  6.     $("#icon"+e.graphic.attributes.id).css("background","url('images/blue.png')");  
  7. });  
  8. gLyr.on("mouse-out",function(e){  
  9.     map.setMapCursor("default");  
  10.     var sms = e.graphic.symbol;  
  11.     sms.url = "images/red.png";  
  12.     gLyr.redraw();  
  13.     $("#icon"+e.graphic.attributes.id).css("background","url('images/red.png')");  
  14. });  


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。

 

[javascript] view plain copy
 
 print?
  1. var data = [  
  2.     {  
  3.         "id":"A","name":"拉萨", "x":91.162998, "y":29.71042,  
  4.         "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。"  
  5.     },  
  6.     {  
  7.         "id":"B", "name":"西宁","x":101.797303,"y":36.593642,  
  8.         "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。"  
  9.     },  
  10.     {  
  11.         "id":"C","name":"兰州","x":103.584297,"y":36.119086,  
  12.         "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。"  
  13.     },  
  14.     {  
  15.         "id":"D","name":"成都","x":104.035508,"y":30.714179,  
  16.         "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。"  
  17.     }  
  18. ];
