Introduction

It is very important for Hybrid mobile apps to get the location of customers who are using apps. With Cordova/phone gap, it's very essay to get latitude and longitude details from which you will get details about the customer country, state, city, etc.

Using the Code

Copy code to one Notepad file.
The code contains HTML and script parts.
Enter the latitude and longitude values in the provided text boxes and get the location details :)

JavaScript

//Read the entered latitude and longitude
// values and get Country,State,City, in code detail
//Implemented with CORS   

 <script>
var country,state,city,pinCode;
function createCORSRequest(method, url) {
  var xhr = new XMLHttpRequest();

  if ("withCredentials" in xhr) {
    // XHR for Chrome/Firefox/Opera/Safari.
    xhr.open(method, url, true);

  } else if (typeof XDomainRequest != "undefined") {
    // XDomainRequest for IE.
    xhr = new XDomainRequest();
    xhr.open(method, url);

  } else {
    // CORS not supported.
    xhr = null;
  }
  return xhr;
}

function getLocationDetails()
{
hide();
latitude1=document.getElementById("latitude").value;
longitude1=document.getElementById("longitude").value;

var url="http://maps.googleapis.com/maps/api/geocode/json?latlng="+
        latitude1+","+longitude1+"&sensor=true";
    var xhr = createCORSRequest('POST', url);
           if (!xhr) {
             alert('CORS not supported');
           }
         
           xhr.onload = function() {
        
            var data =JSON.parse(xhr.responseText);
            
            if(data.results.length>0)
            {
            
            var locationDetails=data.results[0].formatted_address;
            var  value=locationDetails.split(",");
            
            count=value.length;
            
             country=value[count-1];
             state=value[count-2];
             city=value[count-3];
             pin=state.split(" ");
             pinCode=pin[pin.length-1];
             state=state.replace(pinCode,' ');         
             document.getElementById("val").innerHTML=country+
               " | "+state+" | "+city+"  | "+pinCode;
            }
            else
            {
             document.getElementById("messageBox").style.visibility="visible";
             document.getElementById("message").innerHTML=
               "No location available for provided details.";
            }
            
           };

           xhr.onerror = function() {
               alert('Woops, there was an error making the request.');
               
           };
        xhr.send();
        
}

function hide()
{
document.getElementById("messageBox").style.visibility="hidden";
}
</script>

You can use the API in Hybrid mobile apps which use HTML, JavaScript, jQuery. In place of CORS, if you use $.ajax service call, that will also show proper results.
