google maps marker on event 'dragend' issue - javascript

So I'm trying to build a simple web app that takes the address from the user and places a marker on that address. After that, the user can drag the marker to another location and the address field should update accordingly. The problem is I cannot get the address field to update automatically on dragend. The best I have done so far is to update when you click the marker but this is a horrible user experience.
tl;dr change the code so that the "address" field gets updated on dragend and not on click.
var geocoder = new google.maps.Geocoder();
var map;
var marker;
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150, 50)
});
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(37.9839, 23.7294);
var mapOptions = {
zoom: 16,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
}
function geocodePosition(pos) {
geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
marker.formatted_address = responses[0].formatted_address;
} else {
marker.formatted_address = 'Cannot determine address at this location.';
}
infowindow.setContent("<b>" + marker.formatted_address + "</b>" + "<br> Drag the marker and click on it to update the address field!");
infowindow.open(map, marker);
});
}
function codeAddress() {
var address = document.getElementById('address').value;
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
if (marker) {
marker.setMap(null);
if (infowindow) infowindow.close();
}
marker = new google.maps.Marker({
map: map,
draggable: true,
position: results[0].geometry.location
});
google.maps.event.addListener(marker, 'dragend', function() {
geocodePosition(marker.getPosition());
});
google.maps.event.addListener(marker, 'click', function() {
newAddress = marker.formatted_address;
document.getElementById("address").value = newAddress;
if (marker.formatted_address) {
infowindow.setContent("<b>" + marker.formatted_address + "</b>" + "<br> Drag the marker and click on it to update the address field!");
} else {
infowindow.setContent("<b>" + address + "</b>" + "<br> Drag the marker and click on it to update the address field!");
}
infowindow.open(map, marker);
});
google.maps.event.trigger(marker, 'click');
}
else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
google.maps.event.addDomListener(window, "load", initialize);

geocoding runs asynchronously, you must update the input when the response arrives, not immediately.
Possible approach to achieve it:
change
google.maps.event.addListener(marker, 'dragend', function() {
geocodePosition(marker.getPosition());
});
...to
google.maps.event.addListener(marker, 'dragend', function() {
var that=this;
geocodePosition(that.getPosition(),
function(){
google.maps.event.trigger(that, 'click');
});
});
now you have a callback-function which may be executed when the response arrives.
To call it change
function geocodePosition(pos) {
geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
marker.formatted_address = responses[0].formatted_address;
} else {
marker.formatted_address = 'Cannot determine address at this location.';
}
infowindow.setContent("<b>" + marker.formatted_address + "</b>" + "<br> Drag the marker and click on it to update the address field!");
infowindow.open(map, marker);
});
}
...to
function geocodePosition(pos,callback) {
geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
marker.formatted_address = responses[0].formatted_address;
} else {
marker.formatted_address = 'Cannot determine address at this location.';
}
infowindow.setContent("<b>" + marker.formatted_address + "</b>" + "<br> Drag the marker to update the address field!");
callback();//<--this will trigger the marker-click
infowindow.open(map, marker);
});
}

How to retrive place details using place id in google place API

I am using Google place API to retrieve place reviews from the API, Here is the code that i am using to retrive data from Google place API its working fine but it is working on place name, i want it to search on place id. I have attachted the js code and screen shot that its working fine.
Screen shot
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {
lat: 41.9030632,

Combine variables in a string, reverse geocoding - javascript

I try to get back the adress of the point where the "user" clicks on the "google map" I have implemented on my website.
I copied the source code form developers.google.com and made a view adaptations. In the source from google, you get the "latlng" by an input field. I get it by a "event".
In my "geocode-function" I sum my "lat" and "lng" parameters together to what they would have looked like if they came out of the input field.
Here is the code:
// Set variables
var clicklat;
var clicklng;
var geocoder = new google.maps.Geocoder();
var infowindow = new google.maps.InfoWindow;
// Listen for click on map
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
clicklat = parseFloat(event.latLng.lat());
clicklng = parseFloat(event.latLng.lng());
geocodeLatLng(geocoder, map, infowindow);
});
// Geocode function
function geocodeLatLng(geocoder, map, infowindow) {
var input = "#{clicklat},#{clicklng}"
var latlngStr = input.split(',', 2);
var latlng = {lat: parseFloat(latlngStr[0]), lng: parseFloat(latlngStr[1])};
geocoder.geocode({'location': latlng}, function(results, status) {
if (status === 'OK') {
if (results[1]) {
map.setZoom(11);
var marker = new google.maps.Marker({
position: latlng,
map: map
});
infowindow.setContent(results[1].formatted_address);
infowindow.open(map, marker);
} else {
window.alert('No results found');
}
} else {
window.alert('Geocoder failed due to: ' + status);
}
});
}
Now, the problem I have is that console.log(input); gives back: #{clicklat},#{clicklng}. Why, the heck, my variables get not implemented there?
It looks like you are trying to usea "jade" and is not working?
Anyway Here is a way to make it work:
// Set variables
//var clicklat;
//var clicklng;
var geocoder = new google.maps.Geocoder();
var infowindow = new google.maps.InfoWindow;
// Listen for click on map
google.maps.event.addListener(map, 'click', function(event) {
placeMarker(event.latLng);
//clicklat = parseFloat(event.latLng.lat());
//clicklng = parseFloat(event.latLng.lng());
geocodeLatLng(geocoder, map, infowindow, event.latLng); //I add this as a parameter
});
// Geocode function
function geocodeLatLng(geocoder, map, infowindow, thelocation) {
// var input = "#{clicklat},#{clicklng}"
// var latlngStr = input.split(',', 2);
// var latlng = {lat: parseFloat(latlngStr[0]), lng: parseFloat(latlngStr[1])};
geocoder.geocode({'location': thelocation}, function(results, status) {
if (status === 'OK') {
if (results[1]) {
map.setZoom(11);
var marker = new google.maps.Marker({
position: results[1].geometry.location,
map: map
});
infowindow.setContent(results[1].formatted_address);
infowindow.open(map, marker);
} else {
window.alert('No results found');
}
} else {
window.alert('Geocoder failed due to: ' + status);
}
});
}

adding infowindow to google maps

I'm trying to add some infowindow content to my markers on a google map. I can query my server, get some data, put the markers on the map. That works. What doesn't work is that nothing happens when I click on the marker. I would think that the infowindow would popup. Unfortunately, it has been so long since I have done google maps programming, I am effectively starting over. For some reason, the marker's click event is not being called. Any suggestions regarding my dumbness are appreciated. TIA

$.get(url, data, function (result) {
for (var i = 0; i < result.length; i++) {
var address = result[i].Address1 + " " +
(result[i].Address2 != null ? result[i].Address2 : "") +
" " + result[i].City + " " + result[i].Province + " " +
result[i].PostalCode + " " + result[i].Country;
var marker = new google.maps.Marker({
position: geocodeAddress(geocoder, map, address),
map: map,
title: address,
content: address
});
makeInfoWindowEvent(infowindow, "test" + i, marker);
}
});
}
function geocodeAddress(geocoder, resultsMap, address) {
geocoder.geocode({ 'address': address }, function (results, status) {
if (status === 'OK') {
resultsMap.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: resultsMap,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
function makeInfoWindowEvent(infowindow, contentString, marker) {
(function (zinfowindow, zcontentString, zmarker) {
zinfowindow.setContent(zcontentString);
google.maps.event.addListener(zmarker, 'click', function () {
zinfowindow.open(map, zmarker);
});
})(infowindow, contentString, marker);
}
</script>
function makeInfoWindowEvent(map, infowindow, contentString, marker) {
infowindow.setContent(contentString);
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
}
Your code crash because when the listener is calling, the value of marker and infowindow have already changed. You can try something like this (just change the makeInfoWindowEvent function):
function makeInfoWindowEvent(map, infowindow, contentString, marker) {
google.maps.event.addListener(marker, 'click', function () {
infowindow.setContent(contentString);
infowindow.open(map, marker);
console.log (contentString);
console.log (marker);
});
}
Normally, the output will be always the same for contentString and marker.
In order to pass the real value of the marker, contentString and infowindow, you have to create an IIFE. Like this, the value of the variables will be copy inside the function:
function makeInfoWindowEvent(map, infowindow, contentString, marker) {
(function (zinfowindow, zcontentString, zmarker) {
zinfowindow.setContent(zcontentString);
google.maps.event.addListener(zmarker, 'click', function () {
zinfowindow.open(map, zmarker);
});
})(infowindow, contentString, marker);
}
However, you do not need to pass map as parameter because the value of map is always the same.
Tell me if you have some questions.

move marker and update place in google maps

I am using google maps, And in a textfield you can type a place and then you will see a marker on the google maps with the coordinates. You can also move the maker and then the coordinates in the info box will be updated. But how to update also the place name in the textfield? Thank you.
This is the jquery script:
var map;
function initMap() {
var geocoder = new google.maps.Geocoder();
var startaddress = $('#form_inp19').val();
geocoder.geocode({ 'address': startaddress }, function (results, status) {
if (status === google.maps.GeocoderStatus.OK) {
startLocationMap = results[0].geometry.location;
map = new google.maps.Map(document.getElementById('map'), {
zoom: 12,
center: startLocationMap
});
geocoder = new google.maps.Geocoder();
document.getElementById('submit').addEventListener('click', function () {
geocodeAddress(geocoder, map);
});
} else {
alert('Place doesnt exist on the map: ' + status);
}
if (typeof google.maps == 'undefined') {
/* custom functions to alert the user to the error */
return 0;
}
});
}//end function initMap
$(document).ready(function () {
if (typeof google.map == 'undefined') {
return 0;
}
map = new google.maps.Map(document.getElementById('map'),
mapOptions);
});
function toggleBounce() {
if (marker.getAnimation() !== null) {
marker.setAnimation(null);
} else {
marker.setAnimation(google.maps.Animation.BOUNCE);
}
}
var marker;
var infowindow;
function geocodeAddress(geocoder, resultsMap) {
if (typeof infowindow != 'undefined') {
infowindow.close();
}
if (typeof marker != 'undefined') {
marker.setMap(null);
}
var address = document.getElementById('address').value;
geocoder.geocode({ 'address': address }, function (results, status) {

});
} else {

}
infowindow = new google.maps.InfoWindow({

But I get the error:
'geocoder' is undefined
I only get this error:
Cannot assign to a function result
document.getElementById('address') = responses[0].formatted_address;
I see the address: responses[0].formatted_address "Belle van Zuylenlaan 23-24, 2642 Pijnacker, Nederland"
But how to get only the place name in the textfield?
Thank you
In your dragend listener,
google.maps.event.addListener(marker, 'dragend', function() {
geocodePosition(marker.getPosition());
});
and
function geocodePosition(pos) {
geocoder = new google.maps.Geocoder();
geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
document.getElementById('yourTextBoxId').value=responses[0].formatted_address;
} else {
document.getElementById('yourTextBoxId').value='Cannot determine address at this location.';
}
});
}
Here is a working example (puts the address received from the reverse geocoder in the infowindow)

How can I display the address of my geocode in an info window? Google maps API

I am using geolocation to get the address of places on my google maps API by looking up the longitude and latitude and returning the results to my page for use in my database.
I have been unable to display these results in my infowindow in my map.
How can I using the code below include the address in my infowindow. It currently displays the long and lat with the following code:
infowindow.setContent('<div><strong>' + marker.getPosition()+ '</strong><br>');
infowindow.open(map, marker);
The function geocodePosition looks up the address of the coordinates and appends it to the html input in my form.
How can I adapt it to update the infowindow too. I have tried many methods now and no success. Any ideas??

marker.getPosition() is not going to provide the street address. Given your current code, your best bet is to move:
infowindow.setContent('<div><strong>' + marker.getPosition()+ '</strong><br>');
to your geocodePosition() function, and then to pass the infowindow object as a second argument to that function.
So in your initialize() function you would modify calls to geocodePosition by including a second argument:
function initialize() {
...
geocodePosition(marker.getPosition(), infowindow);
}
Then in your geocodePosition() function, you would accept the second argument, and update it with the responses[0].formatted_address value. I added variables to make it easier to pass on the values for address and the message.
function geocodePosition(pos, infowindow) {
geocoder.geocode({
latLng: pos
}, function(responses) {
if (responses && responses.length > 0) {
var address = responses[0].formatted_address;
updateMarkerAddress(address);
infowindow.setContent('<div><strong>' + address + '</strong><br>');
} else {
var msg = 'Cannot determine address at this location.';
updateMarkerAddress(msg);
infowindow.setContent('<div><strong>' + msg + '</strong><br>');
}
});
}
You might want to use Google map api - http://code.google.com/apis/maps/documentation/geocoding/#GeocodingRequests
There are others APIs that will give you the same - but most of them will cost money and with Google you get a lot of 'miles' for free.
