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
顯示信息
實現思路:
1、列表與地圖的互動
鼠標經過列表時,修改列表圖標,並根據列表返回的值在地圖上繪藍色的marker;鼠標移出,修改列表圖標為紅色,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
鼠標經過地圖紅色的marker時,修改對應列表圖標,並將紅色 marker的圖片換成藍色的;鼠標移出,修改對應列表圖標,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、數據以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。" } ];
