PObetter approach then setTimeout on Google Map V3
text
Body
copied!<p>in my Asp.net Web Application where i am using the setTimeout to Get rid of geocoder OVER_QUERY_LIMIT, the shorter time out is 10ms which is too longer for me, I have 800 above addresses coming from SQL SERVER which would be increased because of this setTimeout will take about 5 to 7 mints to take places of all the markers on map and that`s frustrating. I researched and saw this link <a href="http://ajaxian.com/archives/settimeout-delay" rel="nofollow">setTimeout: how to get the shortest delay</a></p> <p>but cant figure out what he want to do actually. please someone guide me....</p> <pre><code> function InitializeMap() { // Here am calling the webService by PageMethods in which CityNames, Countries Name will take their places PageMethods.GetCitiesbyUser_Extender(onSucess); var myOptions = { zoom: 0, center: new google.maps.LatLng(-34.397, 150.644), mapTypeId: google.maps.MapTypeId.ROADMAP, }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // Creating latlngbound to bound the markers on map var bounds = new google.maps.LatLngBounds(); //// Creating an array that will contain the addresses var places = []; // Creating a variable that will hold the InfoWindow object var infowindow; // create this to add the marker Cluster on map mc = new MarkerClusterer(map); var popup_content = []; var geocoder = new google.maps.Geocoder(); // image for ballon i want to change default ballon to this var iconimage = "http://chart.apis.google.com/chart?cht=mm&chs=24x32&chco=FFFFFF,008CFF,000000&ext=.png"; var markers = []; // Create this function for passing the values which was taken by webservice cntName is the return in webservice function onSucess(cntName){ // loop through the cntName to pass the individual City one by one from geocode for (i = 0; i < cntName.length; ++i) { //for fixing the issue use closure to localize the cntName[i] variable before passing into geocode and callback function within it. (function CreateMarkAndInfo(address) { geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { places[i] = results[0].geometry.location; var marker = new google.maps.Marker({ position: places[i], title: results[0].formatted_address, map: map, icon: iconimage }); markers.push(marker); mc.addMarker(marker); google.maps.event.addListener(marker, 'click', function () { if (!infowindow) { infowindow = new google.maps.InfoWindow(); } // Setting the content of the InfoWindow afterward infowindow.setContent(popup_content[i]); // Tying the InfoWindow to the marker afterward infowindow.open(map, marker); }); // Extending the bounds object with each LatLng bounds.extend(places[i]); // Adjusting the map to new bounding box map.fitBounds(bounds); // Zoom out after fitBound var listener = google.maps.event.addListenerOnce(map, "idle", function () { if (map.getZoom() < 10) map.setZoom(2); }); } else { // if geocode will end the limit then make delay by timer in order to avoid the OVER_QUERY_LIMIT if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) { setTimeout(function () { CreateMarkAndInfo(address); }, (15)); // here i think i should use better approch but for now it`s ok. } else { alert("Geocode was not successful for the following reason: " + status); } } }); })(cntName[i]);// End closure trick } } } google.maps.event.addDomListener(window, 'load', InitializeMap); </code></pre> <p><strong>Edit:</strong> @just.another.programmer i cant because there is no latitute and longitude in DB, client will add cities and countries by him self thats why i had to convet city and country names by geocode and geocode doing it`s job accuretly here How i am calling the City and country Names by web service</p> <pre><code> [System.Web.Services.WebMethod] [System.Web.Script.Services.ScriptMethod()] public static string[] GetCitiesbyUser_Extender() { System.Data.DataSet dtst = new System.Data.DataSet(); string ses = HttpContext.Current.Session["UserName"].ToString(); USTER.Dal.clsSearch clssearch = new USTER.Dal.clsSearch(); // Assinging the Stroed Procedure Method to DataSet dtst = clssearch.GetAllCitiesByUser(ses); string[] cntName = new string[dtst.Tables[0].Rows.Count]; int i = 0; try { foreach (System.Data.DataRow rdr in dtst.Tables[0].Rows) { // Columns Name in SQL Server Table "CityName" and "CountryName" cntName.SetValue(rdr["CityName"].ToString() +","+ rdr["CountryName"].ToString() , i); i++; } } catch { } finally { } return cntName; } </code></pre>
