Network Programming in .NET

Here’s an AJAX request that gets your longitude and latitude in javascript. It’s using XML, not JSON, since there was some problems using eval() for non-US addresses.

var strUrl = “http://maps.googleapis.com/maps/api/geocode/xml?”;

strUrl += “address=bt489ph “;

strUrl += “&sensor=false”;

ajaxRequest = new XMLHttpRequest();

ajaxRequest.onreadystatechange = function() {

if (ajaxRequest.readyState != 4)

{

return;

};

var xmlDoc = ajaxRequest.responseXML;

var latitude = xmlDoc.getElementsByTagName(‘lat’)[0].firstChild.nodeValue;

var longditude = xmlDoc.getElementsByTagName(‘lng’)[0].firstChild.nodeValue;

alert(latitude);

alert(longditude);

};

ajaxRequest.open(“GET”,strUrl,true);

ajaxRequest.send(null);
