在OpenLayers中查找线串的长度

Question

I have a feature layer using OpenLayers.Control.DrawFeature with OpenLayers.Handler.Path. I want to measure the real length of the path produced. Everything I find on Google tells me to use OpenLayers.Control.Measure, but this is not what I want because it does not provide an editable path.

So how do I measure the DrawFeature line?

Thanks

没关系，有一个名为getLength（）的方法可以调用以获取几何图形的长度。
