1、uniapp小程序中跳转第三方地图

	  address: function(item) {
			const address = item.address;
			const latitude = Number(item.latitude);
			const longitude = Number(item.longitude);	
			uni.getLocation({
				success(res) {
					uni.openLocation({
						latitude: latitude,
						longitude: longitude,
						scale: 15
					});
				}
			});
		}

2、Android与ios

address: function(item) {
			var url = '';
			const address = item.address;
			const latitude = item.latitude;
			const longitude = item.longitude;
			if (plus.os.name == 'Android') {
				var hasBaiduMap = plus.runtime.isApplicationExist({ pname: 'com.baidu.BaiduMap', action: 'baidumap://' });
				var hasAmap = plus.runtime.isApplicationExist({ pname: 'com.autonavi.minimap', action: 'androidamap://' });
				var urlBaiduMap = 'baidumap://map/marker?location=' + latitude + ',' + longitude + '&title=' + encodeURIComponent(address) + '&src=com.bailb.hbb';
				var urlAmap = 'androidamap://viewMap?sourceApplication=com.bailb.hbb&poiname=' + encodeURIComponent(address) + '&lat=' + latitude + '&lon=' + longitude + '&dev=0';
				if (hasAmap && hasBaiduMap) {
					plus.nativeUI.actionSheet({ title: '选择地图应用', cancel: '取消', buttons: [{ title: '百度地图' }, { title: '高德地图' }] }, function(e) {
						switch (e.index) {
							case 1:
								plus.runtime.openURL(urlBaiduMap);
								break;
							case 2:
								plus.runtime.openURL(urlAmap);
								break;
						}
					});
				} else if (hasAmap) {
					if (uni.getSystemInfoSync().platform == 'android') {
						this.$showModal({
							title: '公告',
							concent: '是否打开“高德地图”进行导航？',
							delCancel: false
						})
							.then(res => {
								plus.runtime.openURL(urlAmap);
							})
							.catch(res => {});
					} else {
						uni.showModal({
							title: '公告',
							content: '是否打开“高德地图”进行导航？',
							success: res => {
								if (res.confirm) {
									plus.runtime.openURL(urlAmap);
								}
							}
						});
					}
				} else if (hasBaiduMap) {
					if (uni.getSystemInfoSync().platform == 'android') {
						this.$showModal({
							title: '公告',
							concent: '是否打开“百度地图”进行导航？',
							delCancel: false
						})
							.then(res => {
								plus.runtime.openURL(urlBaiduMap);
							})
							.catch(res => {});
					} else {
						uni.showModal({

							content: '是否打开“百度地图”进行导航？',
							success: res => {
								if (res.confirm) {

								}
							}
						});
					}
				} else {
					//如果是国外应用，应该优先使用这个，会启动google地图。这个接口不能统一坐标系，进入百度地图时会有偏差
					url = 'geo:' + latitude + ',' + longitude + '?q=' + encodeURIComponent(address);
					if (uni.getSystemInfoSync().platform == 'android') {
						this.$showModal({
							title: '公告',
							concent: '是否打开“GoogleMap”进行导航？',
							delCancel: false
						})
							.then(res => {
								plus.runtime.openURL(url);
							})
							.catch(res => {});
					} else {
						uni.showModal({
							title: '公告',
							content: '是否打开“GoogleMap”进行导航？',
							success: res => {
								if (res.confirm) {
									plus.runtime.openURL(url);
								}
							}
						});
					}
				}
			} else {
				// iOS上获取本机是否安装了百度高德地图，需要在manifest里配置，在manifest.json文件app-plus->distribute->apple->urlschemewhitelist节点下添加（如urlschemewhitelist:["iosamap","baidumap"]）
				plus.nativeUI.actionSheet({ title: '选择地图应用', cancel: '取消', buttons: [{ title: 'Apple地图' }, { title: '百度地图' }, { title: '高德地图' }] }, function(e) {
					switch (e.index) {

							break;
						case 2:

							break;
						default:
							break;
					}
					if (url != '') {
						plus.runtime.openURL(url, e => {
							plus.nativeUI.alert('本机未安装指定的地图应用');
						});
					}
				});
