点击地图获取经纬度

//初始化地图对象，加载地图

							zoom:11

//为地图注册click事件获取鼠标点击出的经纬度坐标

	AMap.service('AMap.Geocoder',function(){//回调函数
		//实例化Geocoder
		geocoder = new AMap.Geocoder({
			city: "010",//城市，默认：“全国”
		});

		//逆地理编码
		geocoder.getAddress(lnglatXY, function(status, result) {
		    if (status === 'complete' && result.info === 'OK') {
		       //获得了有效的地址信息:
		       document.getElementById("addressStr").value = result.regeocode.formattedAddress;
