I'm searching for a way to calculate mileage by US State based on an origin, waypoints and destination of a route using Google Maps API v3.
I have tried using Googles Distance Matrix API but this it is calculating the distance between 2 points, which is good, but I need the break down for miles traveled for each State. For taxes purposes (IFTA reports for transportation).
I've done a lot of googling and looked through the documentation but I'm not seeing anything that calculate the mileage per State.
I know how to use Google maps and I know this is possible since I saw it on one video. There is no code I can show because I have no idea how to do it. Any thoughts?
Useful links I have found:
How to Draw Routes and Calculate Route Time and Distance on the Fly Using Google Map API V3 http://www.c-sharpcorner.com/UploadFile/8911c4/how-to-draw-routes-and-calculate-route-time-and-distance-on/
How to Build a Distance Finder with Google Maps API http://www.1stwebdesigner.com/distance-finder-google-maps-api/
Below is a fully functional implementation that uses the Google Maps Javascript API. All you need to add is your own Maps API Key. As noted in the posts referenced above, Google Maps throttles requests at an asymptotic rate, and thus, the longer the route, the longer it will take to calculate. To give a ballpark, a route from New Haven CT to the NJ/PA border takes approximately 5 minutes. A trip from New Haven CT to Los Angeles takes 45 minutes to index. One other note: There are a few state borders that run through bodies of water. Google considers these to be not located in any state, and so reports undefined as the state name. These sections are obviously only a few tenths of a mile in most cases, but I felt I should mention it just to clarify what is going on when that happens.

I have a page with an unknown number of ".city-name" text fields (generated dynamically).
I'm having issues working with the auto-complete results for these fields after they are generated. I think I'm not doing the right things with my loop.
http://jsfiddle.net/w0dwxg4a/
function getPlace_dynamic() {
var options = {types: ['(cities)']};
var inputs = document.getElementsByClassName('city-name');
for (i = 0; i < inputs.length; i++) {
var places = new google.maps.places.Autocomplete(inputs[i], options);
google.maps.event.addDomListener(inputs[i], 'keydown', function (e) {
if (e.keyCode == 13) {
e.preventDefault();
}
});
google.maps.event.addListener(places, 'place_changed', function () {
var results = places.getPlace();
var address_components = results.address_components;
var components = {};
jQuery.each(address_components, function (k, v1) {
jQuery.each(v1.types, function (k2, v2) {
components[v2] = v1.long_name;
});
});
$(inputs).val(components.locality + ", " + components.country);
$(inputs).closest("form").submit();
});
}
}
The desired behaviour for each".city-name" can be seen in the "#txtPlaces" JsFiddle. I need the box value to convert to "City, Country", and then submit once selected.
I have disabled the enter key because that was submitting the autocomplete without switching it over to "City, Country".
I got it using jQuery $.each: Seems to work.
var options = {
types: ['(cities)']
};
var input = document.getElementsByClassName('city-name');
$.each(input, function(i, x){
var this_id = input[i].id;
var this_input = document.getElementById(this_id);
var places = new google.maps.places.Autocomplete(input[i], options);
google.maps.event.addListener(places, 'place_changed', function () {
var results = places.getPlace();
var address_components = results.address_components;
var components = {};
jQuery.each(address_components, function (k, v1) {
jQuery.each(v1.types, function (k2, v2) {
components[v2] = v1.long_name;
});
});
$(this_input).val(components.locality + ", " + components.country);
$(this_input).closest("form").submit();
});
google.maps.event.addDomListener(input[i], 'keydown', function (e) {
if (e.keyCode == 13) {
e.preventDefault();
}
});
})
}
Got this code, that only works when alert (markers.length); is uncommented.
When this javascript alert not shown I dont get any Markers.. Really weird!!
In the body tag I have <body onload="load()" onunload="GUnload()">
Previoslly the load() function is called and other functions :
function showAddress(address) {
if (geocoder) {//+', '+init_street
geocoder.getLatLng(address,
function(point) {
if (!point) {
document.getElementById("place").value="not found";
//alert(address + " not found");
} else {
// document.getElementById("place").value=point.y.toFixed(4) + "," + point.x.toFixed(4);
map.setCenter(point, 16);
marker.setPoint(point);
//marker.openInfoWindowHtml(address);
}
}
);
}
}
//from a point returns and address!
function showPointAddress(response) {
if (!response || response.Status.code != 200) {//not found
//alert("Status Code:" + response.Status.code);
document.getElementById("place").value="not found";
}
else {//found
map.setCenter(marker.getPoint(), 16);
place = response.Placemark[0];
document.getElementById("place").value=place.address;
//document.getElementById("place").value=marker.getPoint().toUrlValue();
}
}
// Creates a marker at the given point with the given number icon and text
function createMarker(p,text) {
var marker = new GMarker(p);
if (text!=""){
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml(text);});
}
return marker;
}
` var geocoder = null;`
` var map = null;`
function load() {//loading the map
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map"));
map.enableScrollWheelZoom();

if (init_street!=""){
geocoder.getLatLng(init_street,function(point) {//set center point in map
if (point){
map.setCenter(point, zoom);
map.addOverlay(createMarker(point,init_street));
map.openInfoWindow(point,init_street);
}
});
}
map.addControl(new GLargeMapControl());

}
}`
function(data, responseCode) {
if(responseCode == 200) {
var texts = [];

geocoder.getLatLng(addresses[i], function (current) {
return function(point) {
if (point) map.addOverlay(createMarker(point,texts[current]));
}
}(i));
}
}//if });
I Understand the issue of needing a callback function to load the markers, but Im lost..
Any help apreciated!! ;)
Thx in advanced!!
This usually happens when fetching data with Ajax or similar. Basically when you fetch the data you need to utilize a callback function to wait for the data. If you don't there is no data to execute on. However, if you pause the execution with a alert() the data will have been fetched in the background.
Think of it as the waiting for the DOM to load before executing Javascript on the page.
I can't give you a better answer as you have not included the code that is calling the function you included.
I followed the example code line by line from:
How do I integrate Salesforce with Google Maps?
I am not receiving any errors but my Map is blank. The map displays the zoom and position toggle but nothing else.
Any ideas on why?
Here is my Controller Code and Page Code Below
public class mapController2 {

/* address = 'USA';
String addr = '%' + address + '%';
accounts = [SELECT Id, Name, BillingStreet, BillingCity, BillingCountry FROM Account
//WHERE Name LIKE :addr OR BillingStreet LIKE :addr OR BillingCity LIKE :addr OR BillingCountry LIKE :addr];
WHERE BillingCountry LIKE :addr];*/
// address = 'Austin';
String addr = '*' + address + '*';
// Or maybe a bit better full-text search query.
List<List<SObject>> searchList = [FIND :addr IN ALL FIELDS RETURNING
Account (Id, Name, BillingStreet, BillingCity, BillingState, BillingCountry)];
accounts = (List<Account>)searchList[0];
}
public List<Account> getAccounts() {
return accounts;

And use the code given as:

Use
https
not
http
It will definately be blank in firefox or chrome if using http and not https. Try https.
I'm trying to submit a query using the postal code to my DB whenever the googlemaps viewport center changes. I know that this can be done with reverse geocoding with something like:
google.maps.event.addListener(map, 'center_changed', function(){
newCenter();
});
...
function newCenter(){
var newc = map.getCenter();
geocoder.geocode({'latLng': newc}, function(results, status){
if (status == google.maps.GeocoderStatus.OK) {
var newzip = results[0].address_components['postal_code'];
}
});
};
Of course, this code doesn't actually work. So I was wondering how I would need to change this in order to extract the postal code from the results array.
Thanks
What I've realized so far is that in most cases the ZIPCODE is always the last value inside each returned address, so, if you want to retrieve the very first zipcode (this is my case), you can use the following approach:
var address = results[0].address_components;
var zipcode = address[address.length - 1].long_name;
You can do this pretty easily using the underscore.js libraray: http://documentcloud.github.com/underscore/#find
_.find(results[0].address_components, function (ac) { return ac.types[0] == 'postal_code' }).short_name
Using JQuery?
var searchAddressComponents = results[0].address_components,
searchPostalCode="";
$.each(searchAddressComponents, function(){
if(this.types[0]=="postal_code"){
searchPostalCode=this.short_name;
}
});
short_name or long_name will work above
the "searchPostalCode" var will contain the postal (zip?) code IF
and only IF you get one from the Google Maps API.
Sometimes you DO NOT get a "postal_code" in return for your query.
Alright, so I got it. The solution is a little uglier than I'd like, and I probably don't need the last for loop, but here's the code for anyone else who needs to extract crap from address_components[]. This is inside the geocoder callback function
// make sure to initialize i
for(i=0; i < results.length; i++){
for(var j=0;j < results[i].address_components.length; j++){
for(var k=0; k < results[i].address_components[j].types.length; k++){
if(results[i].address_components[j].types[k] == "postal_code"){
zipcode = results[i].address_components[j].short_name;
}
}
}
}
$.each(results[0].address_components,function(index,value){
if(value.types[0] === "postal_code"){
$('#postal_code').val(value.long_name);
}
});
You can also use JavaScript .find method which is similar to underscore _.find method but it is native and require no extra dependency.
const zip_code = results[0].address_components.find(addr => addr.types[0] === "postal_code").short_name;
This takes only two for loops. The "results" array gets updated once we found the first "type" to be "postal_code".
It then updates the original array with the newly found array set and loops again.
var i, j,
result, types;
// Loop through the Geocoder result set. Note that the results
// array will change as this loop can self iterate.
for (i = 0; i < results.length; i++) {
result = results[i];
types = result.types;
for (j = 0; j < types.length; j++) {
if (types[j] === 'postal_code') {
// If we haven't found the "long_name" property,
// then we need to take this object and iterate through
// it again by setting it to our master loops array and
// setting the index to -1
if (result.long_name === undefined) {
results = result.address_components;
i = -1;
}
// We've found it!
else {
postcode = result.long_name;
}
break;
}
}
}
You can also use this code, this function will help to get zip on button click or onblur or keyup or keydown.
Just pass the address to this function.
use google api with valid key and sensor option removed as it doesn't required now.
function callZipAPI(addSearchZip)
{
var geocoder = new google.maps.Geocoder();
var zipCode = null;
geocoder.geocode({ 'address': addSearchZip }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//var latitude = results[0].geometry.location.lat();
//var longitude = results[0].geometry.location.lng();
var addressComponent = results[0].address_components;
for (var x = 0 ; x < addressComponent.length; x++) {
var chk = addressComponent[x];
if (chk.types[0] == 'postal_code') {
zipCode = chk.long_name;
}
}
if (zipCode) {
alert(zipCode);
}
else {
alert('No result found!!');
}
} else {
alert('Enter proper address!!');
}
});
}
I use this code to get "Postal code" and "locality", but you can use it to get any other field just changing the value of type:
JAVASCRIPT
var address = results[0].address_components;
var zipcode = '';
var locality = '';
for (var i = 0; i < address.length; i++) {
if (address[i].types.includes("postal_code")){ zipcode = address[i].short_name; }
if (address[i].types.includes("locality")){ locality = address[i].short_name; }
}
I think rather than depending on the index it better checks address type key inside the component. I solved this issue by using a switch case.
var address = '';
var pin = '';
var country = '';
var state = '';
var city = '';
var streetNumber = '';
var route ='';
var place = autocomplete.getPlace();
for (var i = 0; i < place.address_components.length; i++) {
var component = place.address_components[i];
var addressType = component.types[0];
switch (addressType) {
case 'street_number':
streetNumber = component.long_name;
break;
case 'route':
route = component.short_name;
break;
case 'locality':
city = component.long_name;
break;
case 'administrative_area_level_1':
state = component.long_name;
break;
case 'postal_code':
pin = component.long_name;
break;
case 'country':
country = component.long_name;
break;
}
}
places.getDetails( request_details, function(results_details, status){
// Check if the Service is OK
if (status == google.maps.places.PlacesServiceStatus.OK) {
places_postal = results_details.address_components
places_phone = results_details.formatted_phone_number
places_phone_int = results_details.international_phone_number
places_format_address = results_details.formatted_address
places_google_url = results_details.url
places_website = results_details.website
places_rating = results_details.rating
for (var i = 0; i < places_postal.length; i++ ) {
if (places_postal[i].types == "postal_code"){
console.log(places_postal[i].long_name)
}
}
}
});
This seems to work very well for me, this is with the new Google Maps API V3. If this helps anyone, write a comment, i'm writing my script as we speak... so it might change.
Using JSONPath, it's easily done with one line of code:
var zip = $.results[0].address_components[?(#.types=="postal_code")].long_name;
In PHP I use this code. Almost in every conditions it works.
$zip = $data["results"][3]["address_components"];
$zip = $index[0]["short_name"];
Romaine M. — thanks! If you just need to find the postal code in the first returned result from Google, you can do just 2 loops:
for(var j=0;j < results[0].address_components.length; j++){
for(var k=0; k < results[0].address_components[j].types.length; k++){
if(results[0].address_components[j].types[k] == "postal_code"){
zipcode = results[0].address_components[j].long_name;
}
}
}
In a word, that's a lot of effort. At least with the v2 API, I could retrieve those details thusly:
var place = response.Placemark[0];
var point = new GLatLng(place.Point.coordinates[1], place.Point.coordinates[0]);
myAddress = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.Thoroughfare.ThoroughfareName
myCity = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName
myState = place.AddressDetails.Country.AdministrativeArea.AdministrativeAreaName
myZipCode = place.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.PostalCode.PostalCodeNumber
There has got to be a more elegant way to retrieve individual address_components without going through the looping jujitsu you just went through.
This simple code works for me
for (var i = 0; i < address.length; i++) {
alert(address[i].types);
if (address[i].types == "postal_code")
$('#postalCode').val(address[i].long_name);
if (address[i].types == "")
$('#country').val(address[i].short_name);
}
Using Jquery
You cant be sure in which location in the address_components array the postal code is stored. Sometimes in address_components.length - 1 > pincode may not be there. This is true in "Address to latlng" geocoding.
You can be sure that Postal code will contain a "postal_code" string. So best way is to check for that.
var postalObject = $.grep(results[0].address_components, function(n, i) {
if (n.types[0] == "postal_code") {
return n;
} else {
return null;
}
});
$scope.query.Pincode = postalObject[0].long_name;
return $http.get('//maps.googleapis.com/maps/api/geocode/json', {
params: {
address: val,
sensor: false
}
}).then(function (response) {
var model= response.data.results.map(function (item) {
// return item.address_components[0].short_name;
var short_name;
var st= $.each(item.address_components, function (value, key) {
if (key.types[0] == "postal_code") {
short_name= key.short_name;
}
});
return short_name;
});
return model;
});
//autocomplete is the text box where u will get the suggestions for an address.
autocomplete.addListener('place_changed', function () {
//Place will get the selected place geocode and returns with the address
//and marker information.
var place = autocomplete.getPlace();
//To select just the zip code of complete address from marker, below loop //will help to find. Instead of y.long_name you can also use y.short_name.
var zipCode = null;
for (var x = 0 ; x < place.address_components.length; x++) {
var y = place.address_components[x];
if (y.types[0] == 'postal_code') {
zipCode = y.long_name;
}
}
});
It seems that nowadays it's better to get it from the restful API, simply try:
https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_KEY_HERE
Using an AJAX GET call works perfect!
Something like:
var your_api_key = "***";
var f_center_lat = 40.714224;
var f_center_lon = -73.961452;
$.ajax({ url: "https://maps.googleapis.com/maps/api/geocode/json?latlng="+f_center_lat+","+f_center_lon+"&key="+your_api_key,
method: "GET"
})
.done(function( res ) { if (debug) console.log("Ajax result:"); console.log(res);
var zipCode = null;
var addressComponent = res.results[0].address_components;
for (var x = 0 ; x < addressComponent.length; x++) {
var chk = addressComponent[x];
if (chk.types[0] == 'postal_code') {
zipCode = chk.long_name;
}
}
if (zipCode) {
//alert(zipCode);
$(current_map_form + " #postalcode").val(zipCode);
}
else {
//alert('No result found!!');
if (debug) console.log("Zip/postal code not found for this map location.")
}
})
.fail(function( jqXHR, textStatus ) {
console.log( "Request failed (get postal code via geocoder rest api). Msg: " + textStatus );
});
As I got it zip is the last or the one that before last.
That why this is my solution
const getZip = function (arr) {
return (arr[arr.length - 1].types[0] === 'postal_code') ? arr[arr.length - 1].long_name : arr[arr.length - 2].long_name;
};
const zip = getZip(place.address_components);
i think this is the most accurate solution:
zipCode: result.address_components.find(item => item.types[0] === 'postal_code').long_name;
Just search for postal_code in all types, and return when found.
const address_components = [{"long_name": "2b","short_name": "2b","types": ["street_number"]}, { "long_name": "Louis Schuermanstraat","short_name": "Louis Schuermanstraat", "types": ["route"]},{"long_name": "Gent","short_name": "Gent","types": ["locality","political" ]},{"long_name": "Oost-Vlaanderen","short_name": "OV","types": ["administrative_area_level_2","political"]},{"long_name": "Vlaanderen","short_name": "Vlaanderen","types": ["administrative_area_level_1","political"]},{"long_name": "België","short_name": "BE","types": ["country","political"]},{"long_name": "9040","short_name": "9040","types": ["postal_code"]}];
// address_components = results[0]address_components
console.log({
'object': getByGeoType(address_components),
'short_name': getByGeoType(address_components).short_name,
'long_name': getByGeoType(address_components).long_name,
'route': getByGeoType(address_components, ['route']).long_name,
'place': getByGeoType(address_components, ['locality', 'political']).long_name
});
function getByGeoType(components, type = ['postal_code']) {
let result = null;
$.each(components,
function() {
if (this.types.some(r => type.indexOf(r) >= 0)) {
result = this;
return false;
}
});
return result;
}
