ArcGIS API for JavaScript根据点坐标画线

var polyline = new esri.geometry.Polyline([[xxx,xxx],[xxx,xxx]]);var symbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,255,0]), 2);var graphic = new esri.Graphic(polyline, s...

var line = new esri.geometry.Polyline({ "paths": [[[-122.68,45.53], [-122.58,45.55],[-122.57,45.58],[-122.53,45.6]]], "spatialReference": { "wkid": 4326 }});var lineSymbol = new esri.symbol.CartographicLineSymbol( esri.symbol.C...

请参考以下示例,请采纳哦 var line = new esri.geometry.Polyline({ "paths": [[[a1_x,a1_y], [a2_x,a2_y]]], "spatialReference": { "wkid": 4326 } }); var lineSymbol = new esri.symbol.CartographicLineSymbol( esri.symbol.CartographicL...

//定位 function LocationMethod (lon, lat) { var centerPoint = new esri.geometry.Point( lon, lat, new esri.SpatialReference({ wkid: 4490 })); map.centerAt(centerPoint, 16); }

var polyline = new esri.geometry.Polyline([[xxx,xxx],[xxx,xxx]]); var symbol = new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,255,0]), 2); var graphic = new esri.Graphic(polyline,...

var map; var mapID = 'Map1'; function clickHandler(inputGeometry) { alert ('You clicked ' + inputGeometry.get_x() + ', ' + inputGeometry.get_y()); } function setupCustomTool(name) { map = $find(mapID); map.set_mouseMode(ESRI.A...

ArcGIS js 3.22 版本 Map.extent.getCenter() 如果需要在移动后获取移动后的中心点且在mouse-drag-end事件中获取的话 务必延时 setTimeout 200ms 貌似触发了该事件才重新更新中心点的位置

建议你查看arcgis api for javascript官网,有详细的例子可以查看: http://jshelp.thinkgis.cn/jssamples/toolbar_edit.html

ArcGIS javascript API中得到graphic中的point的方法: 思路:利用arcgis中的点阵队列,定义一个坐标,最后映射成一个point就就取到值了。 参考代码如下: Points in Extent //引入js.arcgis.com dojo.require("esri.map"); dojo.require("esri.t...

下面是基本底图加载,不过你可以把这部分改成你想要指定的map服务, 官网例子: var map; require(["esri/map", "dojo/domReady!"], function(Map) { map = new Map("map", { basemap: "topo", center: [-122.45, 37.75], // longitude, latitud...
