webGIS使用JS,高德API完成的智慧校园项目路径规划

代码实现：

   //通过geojson对象来管理覆盖物，显示点geojson.addOverlay(marker)//保存数据（将geojson对象转换成标准的GeoJSON格式对象）saveData(geojson.toGeoJSON())})//从localstroage中读取数据function getData(){if(!localStorage.getItem('geojson')){localStorage.setItem('geojson','[]')}return JSON.parse(localStorage.getItem('geojson'))}//从localstoragr中写数据function saveData(data){localStorage.setItem('geojson',JSON.stringify(data))}function startAnimation(){//console.log(1)//实现路径规划AMap.plugin('AMap.Driving',function(){var driving =new AMap.Driving({map:map,//驾车策略policy:AMap.DrivingPolicy.LEAST_TIME,})//设置起点和终点var start = new AMap.LngLat()//填写自己学校的坐标起点var end = new AMap.LngLat()//填写自己学校的坐标终点//通过geojson得到每一个点的坐标var opts ={waypoints:[],}geojson.eachOverlay(function(item){opts.waypoints.push(item.getPosition())})driving.search(start,end,opts,function(status,result){if(status=='complete'){console.log('success')//实现模拟var lineArr =[]result.routes[0].steps.forEach(function(item){lineArr.push(...item.path)})var marker = new AMap.Marker({map:map,position:start,icon:'https://webapi.amap.com/images/car.png',offset:new AMap.Pixel(-26,-13),autoRotation:true,angle:-90,})var passedPolyline = new AMap.Polyline({map:map,strokeColor:'#AF5',//线的颜色storkeWeight:6,//线宽})marker.on('moving',function(e){passedPolyline.setPath(e.passedPath) })map.setFitView()marker.moveAlong(lineArr,{duration:500,autoRotation:true,})}else{console.log('error')}})})}
