How to Find an intersect coordinate?

Jan 4, 2012 at 6:58 AM

Hi ,all

I have pointed out the define coordinate on the feature,and now I want to use the mousemove event to find out the define coordinate.

However, sometimes  I can find out quickly,but sometimes I just can't find out, I use the function envelope.intersect() to do this, who

can tell me the reason.

thanks!
