Baidu Map API: Customize navigation through multiple points

There is a limit to the number of navigation points that Baidu officially provides to developers: no more than 10 passes. Suppose I have n points in my hand to draw a trajectory, what to do. However, the route for each point and the next point must be Baidu's recommended route.

1, define the driving object: **onsearchcomplete** function can get every driving.search retrieval after the completion of the callback function, where you can get a collection of points to draw

     var driving = new Bmap.drivingroute (map, {onsearchcomplete:function (results) {
              if (driving.getstatus () = = Bmap_ status_success) {
        var plan = Driving.getresults (). Getplan (0);
        var  num = plan.getnumroutes ();
        Alert ("Plan.num:" +num);
        for (Var j =0;j<num; J + +) {
             //by driving an instance, get a series of points of the array
             var pts= plan.getroute (J). GetPath ();    
             var polyline = new Bmap.polyline (pts);    
             Map.addoverlay (polyline); Draw track
            }}}
        );

2. Search parameters: <=10 of multiple passing points. Tip: Do a search between every 11 points, and then search directly at less than 11 points at a time

var  group = Math.floor (POINTLIST.LENGTH/11);
 var mode = Pointlist.length%11;
 if (mode! = 0) {
 var waypoints=pointlist.slice (group*11,pointlist.length-1);//The extra section is a separate search        Driving.search (Pointlist[group*11],pointlist[pointlist.length-1],{waypoints:waypoints});}
for (var i =0;i<group;i++) {         
var waypoints = Pointlist.slice (i*11+1, (i+1) *11); Driving.search (pointlist[i*11), pointlist[(i+1) *11],{waypoints:waypoints});//waypoints means through point
}

Custom 28 Baidu Point coordinate object, call the above method, the effect diagram is as follows:
