traffic light dashboard display
Posted on 2003-11-13
I am trying to set up a web page that has various traffic lights in a dashboard type display. Each traffic light will represent the "state" of an indicator. Each indicator will be represented by a value in a text file (or similar). What I would like to achieve is that when the web page loads, each of the traffic lights checks the value in its associated text file and then displays red, green or amber based on that value (e.g. 1, 2 or 3).
Unfortunately, being a complete web novice I have no idea of how to go about implementing this e.g. where do I get the traffic light graphics, what language do I need to use etc.
Any pointers as to (a) whether this is feasible and (b) how to implement it would be greatly appreciated.
Thanks in advance.
