Question

what is the dependence on if the javascript gets called or Executed? I have two functions which both get called the same way, to be precise:

[self.mapView stringByEvaluatingJavaScriptFromString:
              [NSString stringWithFormat:@"setMarkerAtPosition(%f,%f)",
                                           latlong.latitude, latlong.longitude]];

and

[self.mapView stringByEvaluatingJavaScriptFromString:@"test()"];

but calculateRoute() gets executed while test() is not. How come?

function setMarkerAtPosition(lat, long){
    var position = new google.maps.LatLng(lat, long);
    var marker = new google.maps.Marker({position: position, 
                                              map: map, 
                                            title:"Hello World!", 
                                         animation: google.maps.Animation.DROP});
    var content = "Ich bin eine normale Infobox";
    google.maps.event.addListener(marker, 'click', function() {
                              infowindow.setContent(content);
                              infowindow.open(map,marker); 
                              reportClickedMarker();
                              });

}

function test(){
    alert(currentPosition.latitude + ', ' + currentPosition.longitude);
}

Thank you

You’re not calling calculateRoute() anywhere. test() is getting called because you are calling it with:

[self.mapView stringByEvaluatingJavaScriptFromString:@"test()"];
