Uncaught ReferenceError: google is not defined (Wordpress) - javascript

Below is the code I am working with. I'm trying to fix an error with a map not displaying in all browsers.
In dev tools (chrome), I'm getting a Uncaught ReferenceError: google is not defined error.
$(document).ready(function(){
//google map
function loadGoogleMap() {
var mapOptions = {
scrollwheel: false,
zoom: 14,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map($("#map")[0], mapOptions);
var bounds = new google.maps.LatLngBounds();
var count = 0;
$.each(dealers, function(ind,dealer){
var point = new google.maps.LatLng(dealer.lat,dealer.lng)
var marker = new google.maps.Marker({
position: point,
map: map,
title: dealer.post_title,
icon: icons[count]
});
var infowindow = new google.maps.InfoWindow({
content:'<div class="infowindow">'+
'<strong>' + dealer.post_title + '</strong><br/>' +
'<address>' +
dealer.address1 + '<br/>' +
dealer.city + ', ' + dealer.state + '<br/>' +

dealer.phone + '<br/>' +
(dealer.url != '' ? 'Dealer Website<br/>' : '') +
(dealer.email != '' ? 'Email Dealer<br/>' : '') +
'Get Directions'+
'</div>'
});
google.maps.event.addListener(marker,'click',function(){
infowindow.open(map,marker);
});
// add event listener to distributor list
$('#distributors-list li:eq(' + count + ')').click(function(){
infowindow.open(map,marker);
});
bounds.extend(point);
count++;
});
map.fitBounds(bounds);
}
loadGoogleMap();
// reuse fancybox loading icon script
var loadingTimer, loadingFrame = 1;
var locator_animate_loading = function() {
locatorLoading = $('#ajax-loading-overlay');
if (!locatorLoading.is(':visible')){
clearInterval(loadingTimer);
return;
}
$(locatorLoading).css('background-position', '0 ' + (loadingFrame * -40) + 'px');

You need to wait until google has loaded before running your scripts. Put this somewhere in your document:
$(document).ready(function(){
//google map
function loadGoogleMap() {
var mapOptions = {
scrollwheel: false,
zoom: 14,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map($("#map")[0], mapOptions);
var bounds = new google.maps.LatLngBounds();
function loadScript() {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://maps.googleapis.com/maps/api/js?v=3.exp&' +
'callback=initialize';
document.body.appendChild(script);
}
var count = 0;
$.each(dealers, function(ind,dealer){
var point = new google.maps.LatLng(dealer.lat,dealer.lng)
var marker = new google.maps.Marker({
position: point,
map: map,
title: dealer.post_title,
icon: icons[count]
});
var infowindow = new google.maps.InfoWindow({
content:'<div class="infowindow">'+
'<strong>' + dealer.post_title + '</strong><br/>' +
'<address>' +
dealer.address1 + '<br/>' +
dealer.city + ', ' + dealer.state + '<br/>' +
'</address>' +
dealer.phone + '<br/>' +
(dealer.url != '' ? 'Dealer Website<br/>' : '') +
(dealer.email != '' ? 'Email Dealer<br/>' : '') +
'Get Directions'+
'</div>'
});
google.maps.event.addListener(marker,'click',function(){
infowindow.open(map,marker);
});
// add event listener to distributor list
$('#distributors-list li:eq(' + count + ')').click(function(){
infowindow.open(map,marker);
});
bounds.extend(point);
count++;
});
map.fitBounds(bounds);
}
loadGoogleMap();
// reuse fancybox loading icon script
var loadingTimer, loadingFrame = 1;
var locator_animate_loading = function() {
locatorLoading = $('#ajax-loading-overlay');
if (!locatorLoading.is(':visible')){
clearInterval(loadingTimer);
return;
}
$(locatorLoading).css('background-position', '0 ' + (loadingFrame * -40) + 'px');
loadingFrame = (loadingFrame + 1) % 12;
};
$('form.distributor-search').submit(function(e){
locatorLoading = $('#ajax-loading-overlay');
locatorLoading.show();
loadingTimer = setInterval(locator_animate_loading, 66);

Mapbox Javascript API function event call order

I am only attaching the script tag. Below is the flow of events that happen and the problem I see. I would appreciate any suggestions/advice.
I trigger the businessGeocoder by searching for an address, which triggers the businessAddress function inside the initialize function, which in turn triggers the businessLocationClickInfo function. This works perfectly.
Without refreshing the page I decide to use the employeeResidenceGeocoder by searching for an address, which triggers the employeeResidenceAddress function inside the initialize function, which in turn triggers the employeeResidenceLocationClickInfo function. This works perfectly. too.
Again, without refreshing the page I decide to use the businessGeocoder again by searching for an address, which triggers the businessAddress function inside the initialize function, which in turn SHOULD trigger the businessLocationClickInfo function, but instead, it triggers the employeeResidenceLocationClickInfo function. The employeeResidenceLocationClickInfo function, while it should have not been called, returns the correct data. I am having a hard time understanding why it is being called instead of the businessLocationClickInfo function.
Please note that doing it the other way, using employeeResidenceGeocoder first and then businessGeocoder, and then back to employeeResidenceGeocoder causes the same problem.
Update>> I ran console logs after each line and found out that because the click events are called in the initialize function, every time I click on the map both businessLocationClickInfo and employeeResidenceLocationClickInfo are being called, one replacing the other output div, whereas I want to only call one of them, depending on the geocoder. But I still haven't found a way/order to fix it.

Newbie Center/Set Zoom of Map to cover all visible Markers? [duplicate]

Center/Set Zoom of Map to cover all visible Markers?
(4 answers)
Closed 6 years ago.
I am not a java programmer but I am using some code I found to create a map with multiple markers on so that I can display it within my application. I want the map to be positioned so that it is in the centre of all the markers zoomed out to see them all. I have found some code that that should do this but I don't know where to put it within the code I have. I am also a little unsure if the code i have is good and efficient. Any help would be most appreciated. The code I believe I need is
var markers = [];//some array
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(markers[i].getPosition());
}
map.fitBounds(bounds);
and my code is.....

Google Map Geocoded TypeError in Callback function

I have the following 2 functions to pull in, geocode, and place markers in a google map.
I keep getting a TypeError: adds[i] is undefined, which of course is causing the rest of the map to bomb.
Here is my code:
// Place Markers on the Map
var PlaceMarkers = function (iw, adds, gc) {
var image = {url: "http://meatmysite.com/Images/star2.png", size: new google.maps.Size(24, 24)};
var aCt = adds.length;
for(var i = 0; i < aCt; ++i) {
GetLatLng(gc, adds[i].address, function(pos) {
if(pos) {
var ipop = '<h1>' + adds[i].title + '</h1>'; // <----- TypeError: adds[i] is undefined
if(!isBlank(adds[i].url)){
ipop += '' + adds[i].url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content' + i + '">' + adds[i].content + '</div>';
if(!isBlank(adds[i].mainphone)){
ipop += '<br /><strong>Phone:</strong> ' + adds[i].mainphone + '';
}
if(!isBlank(adds[i].mainemail)){
ipop += '<br /><strong>Email:</strong> ' + adds[i].mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({title: adds[i].title, position: pos, map: map, icon: image, html: ipop});
google.maps.event.addListener(mark, 'click', function(){
iw.setContent(this.html);
iw.open(map, this);
});
}
});
}
};
// Get Lat/Lng Location
var GetLatLng = function(gc, add, f) {
var ret = '';
gc.geocode({'address': add}, function(res, status) {
if (status == 'OK') {
f(res[0].geometry.location);
console.log('Found Here: ' + ret.toString());
}
});
return -1;
};
DEMO RETURNED DATA FOR adds
[
{
"address": "1 My Street Gilbert, AZ 85234",
"title": "My Title 1",
"url": "http://www.myurl.com/",
"mainphone": null,
"mainemail": null,
"content": "1 My Street<br />Gilbert, AZ 85234"
},
{
"address": "2 My Street North Richland Hills, TX 76182",
"title": "My Title 2",
"url": null,
"mainphone": null,
"mainemail": null,
"content": "2 My Street<br />North Richland Hills, TX 76182"
}
]

One option, pass the complete "address" object into the GetLatLng function, and from there into its callback (so you get function closure on it):
// Get Lat/Lng Location
var GetLatLng = function (gc, add, f) {
gc.geocode({
'address': add.address
}, function (res, status) {
if (status == 'OK') {
f(res[0].geometry.location, add);
}
});
};
Then use it like this inside the callback (you could pass just the index into the array also):
GetLatLng(gc, adds[i], function (pos, add) {
if (pos) {
var ipop = '<h1>' + add.title + '</h1>';
if (!isBlank(add.url)) {
ipop += '' + add.url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content' + i + '">' + add.content + '</div>';
if (!isBlank(add.mainphone)) {
ipop += '<br /><strong>Phone:</strong> ' + add.mainphone + '';
}
if (!isBlank(add.mainemail)) {
ipop += '<br /><strong>Email:</strong> ' + add.mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({
title: add.title,
position: pos,
map: map,
icon: image,
html: ipop
});
google.maps.event.addListener(mark, 'click', function () {
iw.setContent(this.html);
iw.open(map, this);
});
}
});

This looks like a typical binding issue. By the time your callback is called, the value of adds[i] will have changed. It is likely that the loop terminated and i has now a value of last index + 1, which is pointing to nothing. Note that it could also point to the wrong index, that would not fail but use the wrong data.
You must bind the value of adds[i] locally for each iteration or the callback will just use a reference to a global value. There a multiple ways to go about this, here is a simple one where we keep passing adds[i] along as a function argument.
Replace adds[i].address with adds[i] when calling GetLatLng and add a second parameter add to the callback:
GetLatLng(gc, adds[i], function(pos, add) {
...
});
Then modify GetLatLng to use add.address instead of just add and add add to the callback call:
// Get Lat/Lng Location
var GetLatLng = function(gc, add, f) {
var ret = '';
gc.geocode({'address': add.address}, function(res, status) {
if (status == 'OK') {
f(res[0].geometry.location, add);
console.log('Found Here: ' + ret.toString());
}
});
return -1;
};
Then in the callback function, replace all instances of adds[i] with add to use the local variable.
I didn't set up a test but it should theoretically work.

you appear to be overcomplicating things. Any reason why you can't do this?
// Place Markers on the Map
var PlaceMarkers = function (iw, adds, gc) {
var aCt = adds.length;
for(var i = 0; i < aCt; ++i) {
var obj=adds[i];
GetLatLng(gc, obj)
}
};
// Get Lat/Lng Location
var GetLatLng = function(gc, obj) {
var ret = '';
gc.geocode({'address': obj.address}, function(res, status) {
if (status == 'OK') {
var pos=res[0].geometry.location;
var ipop = '<h1>' + obj.title + '</h1>'; // <----- TypeError: adds[i] is undefined
if(!isBlank(obj.url)){
ipop += '' + obj.url + '<br />';
}
ipop += '<div class="map_item_content" id="mi_content">' + obj.content + '</div>';
if(!isBlank(obj.mainphone)){
ipop += '<br /><strong>Phone:</strong> ' + obj.mainphone + '';
}
if(!isBlank(obj.mainemail)){
ipop += '<br /><strong>Email:</strong> ' + obj.mainemail + '';
}
console.log('HEY NOW: ' + pos.toString() + ' - Location Found!');
var mark = new google.maps.Marker({title: obj.title, position: pos, map: map, html: ipop});
google.maps.event.addListener(mark, 'click', function(){
iw.setContent(this.html);
iw.open(map, this);
});
} else {
console.log("geocoder problem!")
}
});
};

for(var i = 0; i < aCt - 1; ++i). You need to add "-1" in you for-loop. The array starts at index 0 and not 1. You also need to be careful with using functions in a for loop. Within javascript a for-loop does not have a scope from itself. Only functions create new scopes.

Google Map:- InvalidValueError: setIcon: not a string; and no url property; and no path property

I am getting this error in google maps.
Error: InvalidValueError: setIcon: not a string; and no url property; and no path property
Earlier it was working fine and i never changed my code.
I have seen a post Google Maps Error: Uncaught InvalidValueError: setIcon: not a string; and no url property; and no path property with same issue and applied the change mentioned in the answer. Earlier it was working and now it also stopped working.
It Seems that google has changed something in their API but not sure what exactly. I found the same issue found by some other users too # https://code.google.com/p/gmaps-api-issues/issues/detail?id=7423
My website link is http://www.advantarealty.net/Search//Condo,Single-Family-Home,Townhome_PropertyType/True_ForMap/ just open in firefox and see the error console.
I have included below js files for map.

f = this.area() * 6;
return new Point(x / f, y / f);
};
$(".SearchProp").hover(function () {
var lat = $(this).attr("lat");
var long = $(this).attr("long");
var sequence = $(this).attr("seq")
google.maps.event.trigger(m[sequence], "mouseover");
var laLatLng = new google.maps.LatLng(lat, long);
});
</script>

Finally I figured out the issue.
Earlier markerwithlabel javascript library, if we want to hide the marker and only want to show the label, we just pass an empty braces to icon parameter like below
var marker = new MarkerWithLabel({
position: latlng,
draggable: false,
raiseOnDrag: false,
map: map,
labelContent: "$" + (json[i].SALE_PRICE / 1000) + 'k',
labelAnchor: new google.maps.Point(22, 0),
labelClass: "marker", // the CSS class for the label
icon: {},
title: json[i].Address,
id: json[i].MLS_ID + '-' + json[i].MLS_LISTING_ID
});
icon: {},
But now it doesn't work, you must have to supply an image icon for that. SO when I supplied a transparent image to icon, it works now.
icon: '/images/transparent-1x1.png',
Also I am now using latest js library for that
http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.1.10/src/markerwithlabel.js

I happened to fall in the same issue and below is the solution which helped me, I hope this helps you too.
First add this google marker with label script in a JS file- (mine is MarkerWithLabel.js)
https://code.google.com/p/google-maps-utility-library-v3/source/browse/trunk/markerwithlabel/src/markerwithlabel.js?r=131
Then add the below mentioned google map JS libraries on the page-
https://maps.googleapis.com/maps/api/js?key=some_key_here&sensor=false
~/Scripts/MarkerWithLabel.js
function showMap() {
var address = $('#corp-add').text();
var geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
var mapOptions = {
center: new google.maps.LatLng(latitude, longitude),
zoom: 16
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var marker = new MarkerWithLabel({
position: new google.maps.LatLng(latitude, longitude),
draggable: true,
raiseOnDrag: true,
map: map,
labelContent: "$425K",
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: { opacity: 0.75 }
});
var iw1 = new google.maps.InfoWindow({
content: "This is a test marker"
});
google.maps.event.addListener(marker, "click", function (e) { iw1.open(map, this); });
}
});
In my code above I am using Google GeoCoder to convert address to Latitudes and Longitudes. You can modify the above code according to your requirements.
You can also follow these links and they might be helpful-
http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerwithlabel/1.1.8/docs/examples.html
Let me know if you need more details from me.

How to find the current location(longitude and latitude) using Google Map?

I just want to ask how can I get the current latitude and longitude using Google Map? Because I am creating a Map Tool for adjusting maps in database. If there is a given latitude and longitude simply display the map. I have no problem with that. But if the longitude and latitude is NULL or 0. How can I get the exact latitude and longitude?
I have this PHP:
for ($i = 0; $i <= $companies_count; $i++) :
$company = $companies[$i];
$company_id = $company['company_id'];
$file_id = $addresses_file[$i]['company_id']; //file information from textfile
$file_latitude = $addresses_file[$i]['new_lat'];
$file_longitude = $addresses_file[$i]['new_long'];
foreach($addresses_file as $y){
if($company_id == $y['company_id']){
$lat = $y['new_lat'];
$long = $y['new_long'];
}else{
$lat = $additionals[$company_id]['geo_lat'];
$long = $additionals[$company_id]['geo_long'];
if($lat == 0 || $lat == NULL){
//set lat to current position
}
if($long == 0 || $long == NULL){
//set long to current position
}
}
}
endfor;
...and my JavaScript:
var maps = {},
geocoder = null;
function showAddress(address, i) {
if (geocoder) {
geocoder.geocode( { 'address' : address },
function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var id = i;
var center = results[0].geometry.location;
document.getElementById("lat_" + id).innerHTML = center.lat().toFixed(5);
document.getElementById("long_" + id).innerHTML = center.lng().toFixed(5);
maps[id].mapObj.setCenter(center);
maps[id].marker.setPosition(center);
$('html, body').animate({
scrollTop: $("tr[rel='" + id + "']").offset().top
}, 1000);
}else{
alert("Geocode was not successful for the following reason: " + status);
}
}
);
}
}
function fn_initialize() {
geocoder = new google.maps.Geocoder();
var hh_map = {
init: function(lat, lon, z_lvl, label, id){
var latlng = new google.maps.LatLng(lat, lon);
var mapOptions = {
zoom: z_lvl,
mapTypeId: google.maps.MapTypeId.ROADMAP,
streetViewControl: false,
overviewMapControl: false,
mapTypeControl: false,
panControl: false,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.SMALL,
position: google.maps.ControlPosition.LEFT_BOTTOM
},
center: latlng,
};
var map = new google.maps.Map(document.getElementById("map_canvas_" + id), mapOptions);
var marker = new google.maps.Marker({
map: map,
position: map.getCenter(),
title: label,
draggable: true
});
google.maps.event.addListener(marker, 'dragend', function(e) { // update lat_{id}/long_{id}
var center = marker.getPosition();
document.getElementById("lat_" + id).innerHTML = center.lat().toFixed(5);
document.getElementById("long_" + id).innerHTML = center.lng().toFixed(5);
});
maps[id] = {'mapObj' : map, 'marker' : marker};
}
};
$('.map_canvas').each(function(){
if ($(this).data('lat') && $(this).data('long')) {
hh_map.init($(this).data('lat'), $(this).data('long'), 16, $(this).data('label'), $(this).data('company_id'));
}
})
}
function loadScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&callback=fn_initialize";
document.body.appendChild(script);
}
window.onload = loadScript;
$(document).ready(function(){
//update address
$('.save-button').each(function(index, elm){
$(elm).click(function(){
var id = $(this).attr("id"),
val_lat = $('#lat_' + id).html(),
val_long = $('#long_' + id).html();
if (val_lat.length > 0 && val_long.length > 0) {
var x = confirm("Are you sure you want to update this?");
if(x == true){
$('<form action="" method="POST">' +
'<input type="hidden" name="company_id" value="' + id + '">' +
'<input type="hidden" name="new_lat" value="' + val_lat + '">' +
'<input type="hidden" name="new_long" value="' + val_long + '">' +
'</form>').submit();
}else{
return false;
}
} else {
alert('New locations are empty!');
}
return false;
})
})
$('.revert-button').each(function(index, elm){ //revert address
$(elm).click(function(){
var id = $(this).attr("id"),
val_lat = $('#lat_' + id).html(),
val_long = $('#long_' + id).html();
if (val_lat.length > 0 && val_long.length > 0) {
var x = confirm("Are you sure you want to revert this?");
if(x == true){
$('<form action="" method="POST">' +
'<input type="hidden" name="company_id" value="' + id + '">' +
'<input type="hidden" name="new_lat" value="' + val_lat + '">' +
'<input type="hidden" name="new_long" value="' + val_long + '">' +
'</form>').submit();
}else{
return false;
}
} else {
alert('New locations are empty!');
}
return false;
})
})
})

With JavaScript, you can use:
var center = map.getCenter();
alert(center.lat() + ', ' + center.lng());
