Using ajax and json to ge the driving distance between two addresses

Question

Is it possible to use the jQuery ajax function and the Google directions API to asynchronous calculate the distance in miles between two given addresses? I've found a few examples that show how to do this using PHP, but nothing that doesn't require a page reload

Why not do it in PHP and use AJAX to get the result from your PHP? — I wrestled a bear once., Oct 14 '14 at 22:16

Yes just implement your calculation in php, and call your script asynchronously using ajax:

$.ajax({
    url: "calcdist.php?address1="+addr1+"&address2="+addr2,
    success: function(result){
        alert("Distance is "+result+" miles);
    }
});

and in your script (calcdist.php):

<?php
$a1 = $_GET['address1'];
$a2 = $_GET['address2'];

$ll1 = getLatLong($a1);
$ll2 = getLatLong($a2);

$dist = haversine($ll1, $ll2);

echo $dist;
?>

You just need to implement the haversine and getLatLong functions in your php

see Haversine formula with php + http://code.google.com/p/gogeocode/ for help with these
