I have to admit, I wing it a bit with Google Maps API. A lot of copy and pasting and basic edits. This code works really well unless a street view image is not available. What is the easiest way to detect no image and hid the pano div? Or the other way round, display it if there is an image:
function googleMap() {
var geocoder = new google.maps.Geocoder();
if (geocoder) {
alert('<?php echo $phoneDirectory->Address; ?>');
geocoder.geocode({ 'address': '<?php echo $phoneDirectory->Address; ?>' }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var googleLat = results[0].geometry.location.lat();
var googleLong = results[0].geometry.location.lng();
//alert(googleLat + ", " + googleLong);
var fenway = new google.maps.LatLng(googleLat,googleLong);
var mapOptions = {
center: fenway,
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(
document.getElementById('map_canvas'), mapOptions);
var panoramaOptions = {
position: fenway,
pov: {
heading: 0,
pitch: 0
}
};
var panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'),panoramaOptions);
map.setStreetView(panorama);
// **** ADDED TO GET WORKING!!! *****
var client = new google.maps.StreetViewService();
client.getPanoramaByLocation(fenway, 50, function(result, status) {
if (status == "ZERO_RESULTS") {
// Hide street view div
$('#pano').css("display", "none");
}
});
googleMapLoaded = true;
}
else {
alert('No results found: ' + status);
}
});
}
}
Check this
If there are no nearby panoramas the result is ZERO_RESULTS

I'm using the Google Geocoding API to build a map that puts markers on whichever locations are requested. At the moment it auto-zooms to each location individually - how do I use fit Bounds to make it zoom to all the locations, i.e. if Sydney is input first, then London, how do I ask it to auto-zoom so the user can view both?
I'm very new to this so any advice welcome!
I've tried many different way to use bounds, fit Bounds, marker.length etc but none of it works or makes much sense to me.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 45.1497, lng: 100.0943},
zoom: 3
});
var geocoder = new google.maps.Geocoder()
var step1 = location.href.split("?")[1].split("=")[1]
$("#address1").val(step1);
geocodeAddress1(geocoder, map);
$(".steps").keypress(function() {
if (event.which == 13) {
geocodeAddress(geocoder, map);
}
})
};
var labelIndex = 0;
function geocodeAddress1(geocoder, resultsMap) {
var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var address = $("#address1").val();
geocoder.geocode({'address': address}, function(results, status) {
if (status === 'OK') {
resultsMap.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: resultsMap,
label: labels[labelIndex++ % labels.length],
position: results[0].geometry.location
});
} else {
alert('Search not successful: ' + status);
}
})
};
function geocodeAddress(geocoder, resultsMap) {
var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var nextstep = "#".concat(event.target.id);
debugger;
var address = $(nextstep).val();
geocoder.geocode({'address': address}, function(results, status) {
if (status === 'OK') {
resultsMap.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: resultsMap,
label: labels[labelIndex++ % labels.length],
position: results[0].geometry.location
});
} else {
alert('Search not successful: ' + status);
}
})
};
You need to store all the markers/loations first in an array each time you click "Geocode", then call bounds.extend() for each location searched to contain the given point and lastly call resultsMap.fitBounds() to set the viewport to contain the given bounds.
var marker = new google.maps.Marker({
map: resultsMap,
position: results[0].geometry.location
});
markerCount++;
markers[markerCount] = marker;
// extend the bounds here to consider each location
bounds.extend(results[0].geometry.location);
// then call fitBounts()
resultsMap.fitBounds(bounds);
Here's a working sample in JSFiddle.
Hope it helps!
I should have on my hands what is proper working JS and an xml file...I'm simply trying to take advantage of the huge database of locations that has been offered up as free for everyone to use - located # http://www.craftbeer.com/breweries/brewery-locator/find-a-us-brewery
I'm tried using their maps.js and xml file...but all I end up with is a blank maps screen...
Here is the Javascript...

EDIT:
Everything worked as expected once I included the following script inline on the page prior to calling the maps.js file. Thanks everyone!
<script>
$(document).ready(function(){
var latitude = 39.300299;
var longitude = -97.382812;
view_map('./uploads/your_xml_file.xml', latitude,longitude,4);
//scripts to handle mapping are in js/mylibs/map.js.php
});
</script>
Looking at the html and the code you provided above I constructed a fiddle for you:
http://jsfiddle.net/loanburger/qafsex5x/
I added two markers in an xml string at the top in the fiddle.
I basically parse the xml doing this:
var markers = $(xml).find("marker");
Its then simply the same for loop you had:
for (var i = 0; i < markers.length; i++)
{
...
}
The fiddle will show you the markers.
This is my code for places autocomplete and search.
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places">
</script>
<script>
var geocoder;
var map;
function initialize() {
var input = document.getElementById('address');
var options = {
componentRestrictions: {country: "in"}
};
var autocomplete = new google.maps.places.Autocomplete(input,options);
geocoder = new google.maps.Geocoder();
//var latlng = new google.maps.LatLng(18.52043030000, 73.85674369999);
var mapOptions = {
zoom: 15,
//center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
}
map = new google.maps.Map(document.getElementById('googleMap'), mapOptions);
}
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);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
This is my html code.
<input id="address" type="textbox" size="30">
<input type="button" value="Search" onclick="codeAddress()">
It is working fine but I dont want to user to click the button. When suggestions appeared, and when user select any of suggestion options, map will have to navigate to that place. How do I do this???
When User select any option from dropdown, map should navigate to that place.
Take a look at this example and the implementation of the place_changed event.
var place = autocomplete.getPlace();
// If the place has a geometry, then present it on a map.
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
}
This way you can pan the map to the location of the autocomplete result.
This is my working code..

//var latlng = new google.maps.LatLng(18.52043030000, 73.85674369999);
var mapOptions = {

//center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
}
map = new google.maps.Map(document.getElementById('googleMap'), mapOptions);
var infowindow = new google.maps.InfoWindow();
var marker = new google.maps.Marker({
map: map,
anchorPoint: new google.maps.Point(0, -29)
});
google.maps.event.addListener(autocomplete, 'place_changed', function() {
infowindow.close();
marker.setVisible(false);
var place = autocomplete.getPlace();
if (!place.geometry) {
return;
}
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(17); // Why 17? Because it looks good.
}
marker.setIcon(/** #type {google.maps.Icon} */({
url: place.icon,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(35, 35)
}));
marker.setPosition(place.geometry.location);
marker.setVisible(true);
var address = '';
if (place.address_components) {
address = [
(place.address_components[0] && place.address_components[0].short_name || ''),
(place.address_components[1] && place.address_components[1].short_name || ''),
(place.address_components[2] && place.address_components[2].short_name || '')
].join(' ');
}
infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
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);
var marker = new google.maps.Marker({

});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);

Now user can select option from dropdown and map will navigate to that place. And also on search button click.
Hope this might help you

Any help is greately appreciated.
I am not much aware of google api and maps.
I'd like to lean up my initialize() function... but every time I do, it breaks my code.
I'm eventually trying to do something like this, where I have a sidebar with stuff that's directly related to the markers on the map, AJAX'd in... Firstly, I'd like to be able to put other functions outside of the initialize() function. This works fine:
<script>
function initialize() {
// create the map object
var mapOptions = {
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
// create your location marker
var mylocOptions = {
draggable: true,
animation: google.maps.Animation.DROP,
icon: new google.maps.MarkerImage('//maps.gstatic.com/mapfiles/mobile/mobileimgs2.png',
new google.maps.Size(22,22),
new google.maps.Point(0,18),
new google.maps.Point(11,11)),
title: "You are here..."
};
var myloc = new google.maps.Marker(mylocOptions);
// get location information from browser, or from user input, or from database
<% if !signed_in? || !current_user.loc %>
if (navigator.geolocation) navigator.geolocation.getCurrentPosition(function(pos) {
var me = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
myloc.setPosition(me);
myloc.setMap(map);
map.setCenter(me);
$.ajax({
data: { me: me.toString() },
type: 'POST',
url: '/set-location'
})
}, function(error) {
var address = prompt('Where are you looking?');
geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': address }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var me = results[0].geometry.location
myloc.setPosition(me);
myloc.setMap(map);
map.setCenter(me);
} else {
alert("Geocode was not successful for the following reason: " + status);
};
});
});
<% else %>
var me = new google.maps.LatLng(<%= current_user.loc %>);
myloc.setPosition(me);
myloc.setMap(map);
map.setCenter(me);
map.setZoom(12);
<% end %>
// watch for marker movement, and update location accordingly
var oldPos = myloc.getPosition();
google.maps.event.addListener(myloc, "dragend", function(e){
revGeo = new google.maps.Geocoder();
var newPos = myloc.getPosition();
$.ajax({
data: { me: newPos.toString() },
type: 'GET',
url: '/set-location'
})
if(oldPos != newPos)
revGeo.geocode({'latLng': newPos}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
$('#loc').html(results[1].formatted_address);
}
} else {
alert("Geocoder failed due to: " + status);
}
});
oldPos = newPos;
});
// when creating an event, check for event location,
// verify it's existance and put a marker down on the map
$(document).on('focusout', '#event_location', function() {
geocoder = new google.maps.Geocoder();
address = document.getElementById("event_location").value;
geocoder.geocode({ 'address': address }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var coords = results[0].geometry.location;
map.setCenter(coords);
var marker = new google.maps.Marker({
map: map,
animation: google.maps.Animation.DROP,
position: coords
});
$('#coords').html('coordinates: ' + coords)
$('#event_geocode').val(coords.toString())
} else {
alert(status + " for " + address);
};
});
});
}
</script>
... but I'm sure it can be broken up. Any ideas of what I'm doing wrong?
