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,缺西陲安宁“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。" 
 } 
];
