Answer 1

您的代码适合我，只修了一些}和]。

但我认为你应该使用polyline代替。

Answer 2

Seem you are searching for google maps direction service

look ad this Direction documentation

and at this direction samples

If is not the direction servici what you are looking for but you want to connect the marker with a line. draw a LineString between every markers coordinate.

how can i plot a route map?
