Select location with map

[Bruce Stuart]

Here's a sample of what I'm doing in the Geolocation service - success event - to SAVE the current location - and then later - set the map center to these values...

[Bruce Stuart]

and finally ps - This also relies on your having checked visible OFF on the default MARKER (not the map) - on your Google Map - in the Appery Designer.

Hi, Thanks a lot your help!
I can now move the marker and the markes is set to the center of my geotrack.
But 2 things:

1. how to get the Markers Location, after it have change place?
2. If i load the page with the map more than one time it comes 1 marker extra for eatch time i refressh, how to fix that?

Hi Hank,

sorry for the delay. Reply in progress. Give me a few ....I'll get the details for you in a second.

Best,

Step 1:

• add these lines of code to the Javascript file you imported above (go to Javascript in the navigator and click on the Javascript file you created above):

  function fRemoveMarker(){
  oGlobalMarker.setMap( null );
  oGlobalMarker = null ;
  return ;
  }

  In your page show event - change the code here to:

  if ( bMarkerDropped ){ fRemoveMarker();}
  bMarkerDropped = false;
  fInitMarker();

  that should take care of the challenge with the multiple markers....

  Next ---- recording the location...

  Best,
  Bruce

Step 2. - AFTER you have step 1 above working (and you don't have duplicate markers any longer) - then ...

Open the Javascript file that you loaded originally - and remove all the contents in the file (Select ALL and then delete the text) - replace it with the contents from this file:

After you've loaded the file - during the test - you'll get an Alert from this function - when you move a marker to the new location - telling you where the new location is.

When this works - you're ready to implement a service in that function - that records the new location to a data store of your choice. (See the commented out code below)....

function fmovemarker( omarker )
{
var stitle = omarker.getTitle();
var oposition = omarker.getPosition();
var nLat = oposition.lat();
var nLng = oposition.lng();
alert('New Position is: ' + oposition.toString() );
// see if the position is within the course bounds....
console.log('moved marker ...:');
localStorage.setItem('n_long', oposition.lng() );
localStorage.setItem('n_lat', oposition.lat() );
// service_updatemarker.execute({});
return ;
}

Thank's a lot!
Works perfect!

Hank, great ! Let me know if you need any help implementing the data service to record the new location.... But you have all the building blocks to do so here !

Best,
Bruce
