我正在尝试使用此代码来做我需要的事情，即在我的地图上有多个折线起点和终点，并能够单击起点标记以显示有关路线的文本。

这个例子的问题是目的地只有一个纬度/经度，但我需要为每个来源添加不同的目的地纬度/经度，以及每个来源的唯一标记文本/标题。谁能告诉我如何做到这一点？

谢谢你的帮助。

你所有的线路最终都在同一个目的地的原因是因为：

path: [lineCoordinates[i], domain[0]],

所以它们从不同的 开始lineCoordinates[i]，但在相同的坐标结束domain[0]，即 11.2583、75.1374。您需要确定您希望它们实际结束的位置，然后进行相应的编码。
