数据表格双击,根据geometry实现地图定位功能

获取geometry传入函数drawGraphic中：
function drawGraphic(geometry){
require([
		"esri/graphic","esri/symbols/SimpleLineSymbol","esri/symbols/SimpleFillSymbol","dojo/colors",
		"esri/toolbars/draw","esri/symbols/SimpleMarkerSymbol"
	],function (Graphic,SimpleLineSymbol,SimpleFillSymbol,Color,Draw,SimpleMarkerSymbol) {
		//根据geometry生成图形graphic
		/*
		下面的代码都是已经封装好的，自己写的话按照下面的步骤写就可以
		var map = new Map("mapDiv"); mapDiv：Container id for the referencing map，存放地图的容器，已封装好，top.window.mainMap就是map
		创建客户端图层
		var graphicsLayer=new GraphicsLayer();已封装好，top.window.mainMap.graphics就是graphicsLayer
		将客户端图层添加到地图中
		map.addLayer(graphicsLayer);框架中已经封装添加过了，不再需要这一步
		*/
		//定义线符号
		var lineSymbol=new SimpleLineSymbol(SimpleLineSymbol.STYLE_DASH, new Color([255, 0, 0]), 3);
		//定义点符号
		var pSymbol=new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE,10, lineSymbol, new Color([255, 0, 0]));
		//定义面符号
		var fill=SimpleFillSymbol(SimpleFillSymbol.STYLE_SOLID, lineSymbol,  new Color([255, 0, 0]));
		//定义图形
		var graphic;
		var type = geometry.type;
		switch(type){
			case "point":
				graphic=new Graphic(geometry,pSymbol);
				break;
			case "polyline":
				graphic=new Graphic(geometry,lineSymbol);
				break;
			case "polygon":
				graphic=new Graphic(geometry,fill);
				break;
		}
		//将图形添加到图层中
		top.window.mainMap.graphics.add(graphic);


		//在地图上绘制图形
		//创建绘图对象
		var toolbar = new Draw(top.window.mainMap, { showTooltips: true });
		//激活绘图工具
		switch(type){
			case "point":
				//激活绘图工具（画点）
				toolbar.activate(Draw.POINT, {
					showTooltips:true
				})
				break;
			case "polyline":
				//激活绘图工具（画折线）
				toolbar.activate(Draw.POLYLINE, {
					showTooltips:true
				})
				break;
			case "polygon":
				//激活绘图工具（绘制面）
				toolbar.activate(Draw.POLYGON, {
					showTooltips:true
				})
				break;
		}

        //top.window.mainMap就是map
		top.window.mainMap.graphics.add(graphic);
		//关掉绘图工具
		toolbar.deactivate();

		//绘制的图形居中显示
		top.window.mainMap.setExtent(geometry.getExtent().expand(2));
