Running Route Database - Update

Been making some improvements to my Running Route Database.
- Reverse Geocoding now works again
- When drawing a new route, it displays the current distance as you draw the map (a la gmapPedometer)
- Simple query engine to search by Country, state, length and bike/run
- Highlight of 5 most recent routes
On the drawing board is:
- Comments / route ratings
- Undo button while creating maps

Hi David,

I've used some of your code on my page:
http://simon.nuttall.name/bicycles/journey/draw.route.html

and I've added and undo button. The code for which is below.

I'd be interested to know how you process the code for the defined route. - I would like to be able to add routes to my database.

cheers,

Simon

HTML:


Undo last line

Javascript:

var points = [];
var lines = [];
var distances = [];
distances.push(0);
var total_distance = 0;

// also I've defined maglob to point to the google map.

GEvent.addListener(map, "click",
function(overlay, point) (
if (points.length == 0) (
map.addOverlay(new GMarker(point));
)
if (point.x != "")(
points.push(point);
var line = new GPolyline(points.slice(points.length-2,points.length),"#0000ff",3,0.5);
lines.push(line);
map.addOverlay(line);
if (points.length > 1) (
total_distance += distance_between_points( points[points.length-2], points[points.length-1] );
distances.push(total_distance);
displayDistance(total_distance);
)
)
)
);

function displayDistance(distance) (
var theParagraph = document.getElementById('routelength');
theParagraph.firstChild.nodeValue = "Route Length: "+Math.round(distance*10*0.621371192)/10+" miles ("+Math.round(distance*10)/10+"km)";

)

function undolastline() (
if (points.length > 1) (
// remove line
points.pop();
mapglob.removeOverlay(lines.pop());
distances.pop();
total_distance = distances[distances.length-1];
displayDistance(total_distance);
) else (
// remove start marker
points.pop();
mapglob.clearOverlays();
total_distance = 0;
displayDistance(total_distance);
)
)
