已解决

已经解决了，犯了一个错误。我以为你不能为 Poly 对象设置 var，但你可以。

问题

我正在尝试创建一个工具，用户可以在其中创建多条折线并将其保存到数据库中。当用户创建一行时，它将作为编码字符串 (encodePath) 保存到数组中。我还希望用户能够通过单击行来删除行，这是我使用的：

google.maps.event.addListener(poly, 'click', function() {
  this.setMap(null);
  polylines[array_id] = ""; //how do i set the array_id to this eventlistener?
}

现在我还需要从数组中删除编码的字符串，我的问题是：如何添加变量（array_id编码字符串）到此事件侦听器？

当我使用上面编写的代码时，它当然给出最后一个 array_id 而不是折线的 array_id 。

SOLVED

Already solved it, made a mistake. I thought you couldn't set a var to the poly object, but you can.

QUESTION

I'm trying to create a tool where users can create multiple polylines and save them into a database. When a users creates a line it is saved as a encoded string (encodePath) into a array. I also want users to be able to delete the lines by clicking on the line, this I did by using:

google.maps.event.addListener(poly, 'click', function() {
  this.setMap(null);
  polylines[array_id] = ""; //how do i set the array_id to this eventlistener?
}

Now I also need to delete the encoded string from the array, my question here is: how do I add a variable (the array_id of the encoded string) to this eventlistener?

When i use the code as written above, it ofcourse gives the last array_id and not the array_id of the polyline.
