Hello,
I'm making an asynchronous call to the Google Maps API to geocode an
address, and I am trying to call a callback function once I receive
the response. I am getting the "object expected" error when I try to
call the callback function. Here is my relevant code:
JAVASCRIPT CODE:
// function for geocoding location, first checking if the location is
the same as the one saved in the database (thus preventing a call to
Google Maps)
function check_geocoding_need(location, stored_location,
latitude_docObject, longitude_docObject, country_docObject) {
if ((location != stored_location) && (location != '')) {
get_geog_coordinates
(location,longitude_docObject,latitude_docObject,country_docObject);
}
}
// function to get geographic coordinates of location using Google
Maps
function get_geog_coordinates
(location,longitude_docObject,latitude_docObject,country_docObject,callback_function)
{
var geocoder = new GClientGeocoder();
geocoder.getLocations(location, function(response) {
if (!response || response.Status.code != 200) { // location not
found
callback_function(1);
} else if(response.Placemark.length > 1) { // more than one
place
matched the location
callback_function(2);
}
});
}
// The callback function
var location_handler = function(result) {
var validation = 1;
if(result == 1) { // loation not found
var error_msg = "Location not found.<br />";
validation = 0;
}
else if (result == 2) { // more than one location found
var error_msg = "Many locations found.<br />";
validation = 0;
}
else { // success!
var error_msg = '';
}
form_validate_sync(validation, error_msg); //call synchronization
function
};
I get the "Object Expected" error at the bolded parts, where it says
"callback_function(1);" and "callback_function(2);".
