I haven't worked with gmaps for about a year now and I am recycling an
old script. Maybe it is just getting late but I expected the following
to draw a line in steps of 100m but nothing is drawn until the while
statement is finished. Why is that?
function getProfile(marker, endPoint, spoke) {
spoke = spoke+1
var mark = 0
var diskm = dis*1000
var start=marker.getPoint();
var end=endPoint;
var dLat = end.lat()-start.lat();
var dLng = end.lng()-start.lng();
while(mark < diskm) {
var latPoints = start.lat() + dLat*mark/diskm;
var lngPoints = start.lng() + dLng*mark/diskm;
var point= new GLatLng(latPoints,lngPoints);
getElevationInter(point.lat(),point.lng());
myLine = new GPolyline([marker.getPoint(), point]);
map.addOverlay(myLine);
window.alert(point) ; //just to slow it down to find
problem
var percentDone=100*mark/diskm;
var percentDoneFix= percentDone.toFixed(0);
var text="getting height data for spoke " + spoke + "... " +
percentDoneFix + "%";
document.getElementById('chart').innerHTML = text;
mark += 100;
}
};
If you want to see the whole script it is at
http://members.chello.at/stephen.joung/testsite/indexLOSRadar.html and
http://members.chello.at/stephen.joung/testsite/losradar_jslint5.js
but it is nowhere near ready yet. After clicking the alert box forty
times the polylines are drawn, but I imagined that a polyline would be
drawn after each click.
Thanks for any assistance.
Steve.
