JavascriptGoogle Maps-Api-3Javascript Problem Overview
All I want is some simple example code that shows me how to obtain a latlng element from an inputted zip code OR a city/state.
Javascript Solutions
Solution 1 - Javascript
Couldn't you just call the following replaceing the {zipcode} with the zip code or city and state http://maps.googleapis.com/maps/api/geocode/json?address={zipcode}
Here is a link with a How To Geocode using JavaScript: Geocode walk-thru. If you need the specific lat/lng numbers call geometry.location.lat() or geometry.location.lng() (API for google.maps.LatLng class)
EXAMPLE to get lat/lng:
var lat = '';
var lng = '';
var address = {zipcode} or {city and state};
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
lat = results[0].geometry.location.lat();
lng = results[0].geometry.location.lng();
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
alert('Latitude: ' + lat + ' Logitude: ' + lng);
Solution 2 - Javascript
Just a hint: zip codes are not worldwide unique so this is worth to provide country ISO code in the request (https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2).
e.g looking for coordinates of polish (iso code PL) zipcode 01-210:
https://maps.googleapis.com/maps/api/geocode/json?address=01210,PL
how to obtain user country code?
if you would like to get your user country info based on IP address there are services for it, e.g you can do GET request on: http://ip-api.com/json
Solution 3 - Javascript
Here is the most reliable way to get the lat/long from zip code (i.e. postal code):

Solution 4 - Javascript
This is just an improvement to the previous answers because it didn't work for me with some zipcodes even when in https://www.google.com/maps it does, I fixed just adding the word "zipcode " before to put the zipcode, like this:
function getLatLngByZipcode(zipcode)
{
var geocoder = new google.maps.Geocoder();
var address = zipcode;
geocoder.geocode({ 'address': 'zipcode '+address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
alert("Latitude: " + latitude + "\nLongitude: " + longitude);
} else {
alert("Request failed.")
}
});
return [latitude, longitude];
}
Solution 5 - Javascript
While working on my internship project I found a website for this https://thezipcodes.com/ Create a free account and get the API key from account Section.
https://thezipcodes.com/api/v1/search?zipCode={zipCode}&countryCode={2digitCountryCode}&apiKey={apiKey}
I found majority of data here.
Solution 6 - Javascript
Here is the function I am using for my work
function getLatLngByZipcode(zipcode)
{
var geocoder = new google.maps.Geocoder();
var address = zipcode;
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();
alert("Latitude: " + latitude + "\nLongitude: " + longitude);
} else {
alert("Request failed.")
}
});
return [latitude, longitude];
}
Solution 7 - Javascript
<script src="https://maps.googleapis.com/maps/api/js?key=API_KEY"></script>
<script>
var latitude = '';
var longitude = '';
var geocoder = new google.maps.Geocoder();
geocoder.geocode(
{
componentRestrictions: {
country: 'IN',
postalCode: '744102'
}
}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
latitude = results[0].geometry.location.lat();
longitude = results[0].geometry.location.lng();
console.log(latitude + ", " + longitude);
} else {
alert("Request failed.")
}
});
