JS在两个或多个点之间画线 [英] JS Draw line between two or more points

问题描述

我需要在两个标签或标签之间画一条线。

i need to draw a line between two tags or tags.

示例：

http://caitriona.github.io/connect-the-dots/

我需要执行以下操作，但此脚本中不执行此操作，但顺序是随机的。

您可以单击 P1，然后单击 P2，然后将绘制线条。但是，如果您单击 P1，然后单击 P3，则会出现一条错误消息（这不是问题）。

I need to do something like this but not like in this script, in an order but randomly.
You can click on "P1" and then on "P2" and the line will be drawn. But if you click on "P1" and then on "P3" an error message should appear (that's not the problem).

我的问题是，我不是一个JavaScript破解者，无法在两点之间划清界限。

My problem is, that I'm not so much a javascript crack to draw the line between the points.

有人可以指出我正确的方向吗？

谢谢！

Can someone point me to the right direction?
Thank you!
