Google Maps API: find a route between two points in Israel_问答_开发者

I am trying to find a route between two points i enter manually at my html page but i get ZERO_RESULTS return value.

The users enters two locations src_address = "Tel Aviv" and dst_address = "Haifa".

i get their geometric location by calling geocoder.geocode twice for each address. then set : src_latlng = results[0].geometry.location; dst_latlng = results[0].geometry.location;

however, when asking for router i get ZERO_RESULTS:

here is the code:

Google doesn't have Maps API coverage for Israel yet, hence the ZERO_RESULTS status returned from the directionsService.route function call.

See Google's map coverage details worksheet of supported regions here. The direct link to the spreadsheet is here.

hi you can use this code to get route between souurce and destinations

function setRoute()
{
      var fromAddress=document.getElementById("txtfromAddress").value;
      var toAddress=document.getElementById("txttoAddress").value; 
      if(fromAddress!="" && toAddress!="")
      {
       if(!fromAddress && !toAddress)
       {
       alert('ROute not found');
       }
       GDir1.load("from: " + fromAddress + " to: " + toAddress);        


      }
      else
      {
        alert('Route Directions Required');
      }
}
