vue+BMap获取两点之间驾车距离和时间

代码：git

<script>
import 'echarts/extension/bmap/bmap'

export default {
        data() {
            return {}
        },
        methods: {
			drawLine() {
				let map = new BMap.Map("container",{enableMapClick: false});
                map.centerAndZoom(new BMap.Point(113.274, 23.135), 14);		// 设置中心点（广州）
                map.clearOverlays();	// 清除地图上的覆盖物
                let start = new BMap.Point(this.entities[0].longitudeFix,this.entities[0].latitudeFix);	// 起始点
                let end   =  new BMap.Point(this.entities[1].longitudeFix,this.entities[1].latitudeFix); 	// 终点

                    let time =  "";
                    let lenth = "";
                    let searchComplete = function (results){
                        if (transit.getStatus() != BMAP_STATUS_SUCCESS){ return ;}  // 检测返回状态
                        let plan = results.getPlan(0);
                        time = plan.getDuration(true) + "\n"; //获取时间
                        lenth = plan.getDistance(true);    //获取距离
                    };

                    let transit = new BMap.DrivingRoute(map, {renderOptions: {map: map},
                        onSearchComplete: searchComplete,
                        onPolylinesSet: function(){
                            setTimeout(function(){},10);
                        }
                    });
                    transit.search(start, end);
			}
		}
}
