i'm trying to update kml files on the fly as described by google here:
https://developers.google.com/kml/documentation/updates?csw=1
my problem is: in my source code i triggered the update-load.kml after a short timeout
function initialize() {
...some code...
myParser.parse('./point-load.kml');
//so far everything is working fine, and the markers show up on the map
window.setTimeout("Update()", 5000);
}
function Update() {
myParser.parse('./update-load.kml');
}
after the update nothing happenes, no markers changed or moved, nothing...
the structure of my .kml files is exactly the same like in the link above
edit:
parsers added to function Update()
function Update() {
var center = new google.maps.LatLng(28.019440, -17.382813); //set map center
var mapOptions = {
zoom: 3, //set default zoom level
center: center,
mapTypeId: google.maps.MapTypeId.ROADMAP //set default map type(ROADMAP,SATELLITE,HYBRID,TERRAIN)
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions); //***ORIGINAL***
var myParser = new geoXML3.parser({map: map});
myParser.parse('./update-load.kml');
}
now: all markers dissapear

I'm using geoXMl3 to parse multiple kml files at a time.
I'm getting polygons plotted on the map. when I click on the polygon an info-window pops up. I'm not getting from where this info-window is coming up
My requirement is I want to edit the content of info-window through some java-script object
My java-script object will be like
popUpDetails = {'district-name':'content'}.
Not getting how to pass this in my parser
I have refered few links like:
https://code.google.com/p/geoxml3/wiki/Usage
and also how could I put data dynamically from database in infowindow of a certain polygon?
I'm parsing kml files this way:
var mapProp = {
center: new google.maps.LatLng(51.508742,-0.120850),
zoom: 5,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
var parser = new geoXML3.parser({
map: map,
processStyles: true,
zoom: false,
});
var infowindow = new google.maps.InfoWindow();
for (i = 0; i < ListofPathsofkmlfiles.length; i++) {
parser.parse([ListofPathsofkmlfiles[i]]);
}
Advance thanks for your help
I have finally figured out solution for same.
You need to overwrite createPolygon attribute of your parser for same.
var districtInfoMap = {doc_url1:infowindow_content1, doc_url2:infowindow_content2 };
var parser = new geoXML3.parser({
createPolygon: mapDrawingToType(),
map: map,
processStyles: true,
zoom: false,
singleInfoWindow: true,
});
mapDrawingToType = function() {
return function(placemark, doc) {
var polygon = geoXML3.instances[geoXML3.instances.length-1].createPolygon(placemark, doc);
if(polygon.infoWindow) {
polygon.infoWindowOptions.content = districtInfoMap[doc.baseUrl];
}
return polygon;
}
}
Here I have made one object containing the map of district url and window content you have to show.
This will overwrite the default behavior of how your infowindow is displayed and the desired content you want to show will be displayed.
If you still face any issue please do let me know.
I'm showing a Google Map within a div using the code below. When the page loads the map appears to bounce around before settling. Is there a way to stop this behavior? The page is here.
function initialize() {
myform.search.focus();
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(41.850033, -87.6500523);
var mapOptions = {
zoom: 2,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
}
The following works for me:
initially set the visibility-style of #map_canvas to hidden
Then wait for the tilesloaded-event to show the map(with a short delay):
google.maps.event
.addListenerOnce(map,
'tilesloaded',
function(){var that=this;
setTimeout(function(){
that.getDiv().style.visibility='visible'},
100);
});
I recently learn t to add custom markers to the Google maps. So i created a route with directions API. After that I added my own markers. Now i am facing a problem where both, the original one and the custom one are showing up. How can i remove the default markers to show my originals one.
Code I wrote to add custom markers
function addmarkers()
{
$.each(order,function(key,value)
{
geocoder.geocode( { 'address': waypts[value]}, function(results)
{
var source = 'images/markers/'+i+'.png';
var latlang = results[0].geometry.location;
var marker = new google.maps.Marker({
position: latlang,
map: map,
icon: source
});
});
});
};
I am calling this function just after the initialize() function
function initialize() // creating maps
{
google.maps.visualRefresh = true;
currentlocation = new google.maps.LatLng(mylat,mylong);
var mapoptions =
{
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: currentlocation
}
map = new google.maps.Map(document.getElementById('map'),mapoptions);
addmarkers();
directionsDisplay.setMap(map);
};
Now you can see in the pic, I am getting both the default as well as the customized markers. Where is this going wrong ?
i am working on google maps, what i want to do is to click on the map it add a marker to the map its working fine but the problem is that i need to move the same marker to a new place if i click some where else instead of new marker. and also when i click on any point it give me the address of that place in a text field
here is my code
<script type="text/javascript">
var map;
var markersArray = [];
function initialize() {
var haightAshbury = new google.maps.LatLng(37.7699298, -122.4469157);
var mapOptions = {
zoom: 7,
center: haightAshbury,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
google.maps.event.addListenerOnce(map, 'click', function(event) {
addMarker(event.latLng);
});
}
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
markersArray.push(marker);
}
// Removes the overlays from the map, but keeps them in the array
function clearOverlays() {
if (markersArray) {
for (i in markersArray) {
markersArray[i].setMap(null);
}
}
}
}
You can call clearOverlays anytime you create a new marker.this way you hide the previous marker and only the new is shown.
another way is to have a var marker just as you have a var map. you can edit the markers position in addMarker.
as far as geocoding is concerned take a look at this
I wanna simply get markers from a kml file and show them on a map, but add "mouseover" for tooltip, not click
using this code, but it don't work (works if i use click)
function initialize() {
var latlng = new google.maps.LatLng(53.477876, -2.471289);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
//kml begin
var nyLayer = new google.maps.KmlLayer('http://code.nebtron.com/kml2.kml', {suppressInfoWindows: false});
nyLayer.setMap(map);
google.maps.event.addListener(nyLayer, "mouseover", function(kmlEvent) {
var text = kmlEvent.featureData.description;
showInDiv(text);
});
function showInDiv(text) {
var sidediv = document.getElementById('contentWindow');
sidediv.innerHTML = text;
}//kml end
}

As pointed out here, there is no mouseover event for KMLLayers. But maybe you could use a polygon. Here's a link.
Hope this helps!
