Latitude and Longitude of a location using Javascript and Google
The following Javascript will help you acquire the latitude and longitude of a location (using an address, zip code, or city).
Note: You will need to have a Google API key which is domain specific.
Place the following code in the <head> section:
View Code JAVASCRIPT
var geocoder; geocoder = new GClientGeocoder(); function submitForm() { var address = document.getElementById("address").value + ", " + document.getElementById("city").value + ", " + document.getElementById("state").value + ", " + document.getElementById("zip").value; geocoder.getLocations(address, getCoords); } function getCoords(response) { if (!response || response.Status.code != 200) { alert("Unable to Create Lat and Lng for plotting."); } else { place = response.Placemark[0]; var lat = place.Point.coordinates[1]; var lng = place.Point.coordinates[0]; } alert("Lat:"+lat+" - Lng:"+lng); } |
Here is the HTML that was used to pass the data:
