network information api (this experimental technology):

the network information api provides information system's connection, in term of general connection type (e.g., 'wifi', 'cellular', etc.). can used select high definition content or low definition content based on user's connection. entire api consists of addition of domxref("networkinformation") interface , single property navigator interface: navigator.connection.

var connection = navigator.connection || navigator.mozconnection || navigator.webkitconnection; var type = connection.type;  function updateconnectionstatus() {   alert("connection type change " + type + " " + connection.type); }  connection.addeventlistener('typechange', updateconnectionstatus);
