The block of code I have in the 2nd "for loop" is:
p[a] = new GPolyline(pts,colour,width)
map.addOverlay(p[a]);
The variable "a" represents a particular line, if "a" were 3 then I'm
interested in points relating to line[3], which would be all the
coordinates for 'lineTFT004.'
Now the line below which is in the very last function (included in the
top post) is:
p[lineIndex].setStrokeStyle({color: col});
The p[lineIndex] in here represents the p[a] which I've shown above.
Since I can pass any value to "lineIndex" via the arguments and also
since I can pass any colour value it should technically change
whatever segment of the road I wish to that particular colour. An
example is:
changeColors(3, "FF0000");
If I do this then it means that "lineIndex" takes the value of 3 hence
my original p[a] should now be p[3] and all the coordinates relating
to p[3] (it should be lineTFT004), I will have full control of to
change that segments' colour.
But now since "lines" is destroyed each time hence my message boxes
are only showing 1,1,1,1 etc... I will not be able to do what I intend
to - thus the only segment I can ever colour and control with my
changeColors() function is a lineIndex of 0, which would be p[0]. Now
this explains why any other lineIndex value other than 0 are not
colouring their respective segment on the road.
So any ideas please on how I can resolve this? I am making full use of
the debugging capabilities I have in firefox,chrome and IE to help me
get through this but really could use some professional advice here.
Thanks,
PS: I've changed the format of my XML to match what Rossko suggested.
