Hey everybody! Im trying to use getLatLng() to geocode a list of postal/zip codes and store the generated point in the database to be placed on a map later. This is what I've got so far:
$(".geocodethis").click(function () {
var geocoder = new GClientGeocoder();
var postalCode = $(this).siblings(".postal").val();
var id = $(this).siblings(".id").val();
geocoder.getLatLng(postalCode, function (point) {
if (!point) {
alert(postalCode + " not found");
} else {
alert(point);
var serializedPoint = $.param(point);
//Geocode(id, point);
}
});
});
function Geocode(id, point) {
alert(point);
$.post("/Demographic/Geocode/" + id, point, function () {
alert("success?");
});
}
but I'm getting this.lat is not a function
in my error console when i try to serialize the point object or use it in $.post()
From my research, I understand that geocoder.getLatLng()
is asynchronous, how would that affect what I'm trying to do? I'm not running this code in a loop, and I'm trying to post the point using the anonymous callback function.
How can I save the information from point
to use later?
Update
Creating a marker and trying to post that still results in the this.lat is not a function
in the error console.
$(".geocodethis").click(function () {
var geocoder = new GClientGeocoder();
var postalCode = $(this).siblings(".postal").val();
var id = $(this).siblings(".id").val();
geocoder.getLatLng(postalCode, function (point) {
if (!point) {
alert(postalCode + " not found");
} else {
alert(point);
var marker = new GMarker(point);
$.post("/Demographic/Geocode/" + id, marker, function () {
alert("success?");
});
}
});
});
** Another Update **
I really need to save the geocoded address for later, even if I store the latitude/longitude values in my database and remake the marker when I'm ready to put it onto a map. Again, serializing or posting - seemingly using the point in any way other than in google maps functions gives the this.lat is not a function
exception in my error log.
I'm using asp.net mvc - are there any frameworks out there that would make this easier? I really need help with this. Thanks.
If your stuck for 2 days maybe a fresh v3 start would be a good thing, this snipped does a similair job for me...
function GetLocation(address) {
var geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
ParseLocation(results[0].geometry.location);
}
else
alert('error: ' + status);
});
}
}
function ParseLocation(location) {
var lat = location.lat().toString().substr(0, 12);
var lng = location.lng().toString().substr(0, 12);
//use $.get to save the lat lng in the database
$.get('MatchLatLang.ashx?action=setlatlong&lat=' + lat + '&lng=' + lng,
function (data) {
// fill textboss (feedback purposes only)
//with the found and saved lat lng values
$('#tbxlat').val(lat);
$('#tbxlng').val(lng);
$('#spnstatus').text(data);
});
}
