    <p>I am trying to get the distance between two location using Google Mps API following <a href="https://stackoverflow.com/questions/10906805/finding-streets-get-their-coordinates-and-calculating-distances-between-marker">this post</a>. I also found the <a href="http://jsfiddle.net/foxwisp/vQGMr/1/" rel="nofollow noreferrer">following example</a>.</p> <p>I have integrated the same code and but I don't see any results. What am I doing wrong here?</p> <p>Can anyone please let me know of any links where the examples have been indicated for Google Maps APIv3?</p> <pre><code> &lt;html&gt; &lt;head&gt; &lt;style&gt; h1{ font-family:arial,helvetica,sans-serif; font-size:20px; font-weight:bold; } p{ font-family:arial,helvetica,sans-serif; } &lt;/style&gt; &lt;script include="/home/rajeev/Desktop/ge/jquery-1.7.2.js"&gt;&lt;/script&gt; &lt;script&gt; var map; var marker, marker2; function initialize() { var mapDiv = document.getElementById('map-canvas'); map = new google.maps.Map(mapDiv, { center: new google.maps.LatLng(-36.86501268451408, 174.723858833313), zoom: 16, mapTypeId: google.maps.MapTypeId.ROADMAP }); } $(function() { initialize(); var geocoder = new google.maps.Geocoder(); //Geocode the first address geocoder.geocode({ address : '27 West View Road Westmere Auckland New Zealand', region: 'no' }, function(results, status){ //Create the first marker marker = new google.maps.Marker({ position: new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng()), map: map, }); //Now geocode the second address geocoder.geocode({ address : '37 Old Mill Road Westmere Auckland New Zealand', region: 'no' }, function(results, status){ //Create the second marker marker2 = new google.maps.Marker({ position: new google.maps.LatLng(results[0].geometry.location.lat(), results[0].geometry.location.lng()), map: map, }); //Now create the line (we have both markers at this point guaranteed) var line = new google.maps.Polyline({ path: new Array(marker.getPosition(),marker2.getPosition()), strokeColor: '#ff0000', strokeOpacity: 1.0, strokeWeight: 2 }); line.setMap(map); //Now calculate the distance var R = 6371; // km var dLat = (marker.getPosition().lat() - marker2.getPosition().lat()).toRad(); var dLon = (marker.getPosition().lng()- marker2.getPosition().lng()).toRad(); var lat1 = marker2.getPosition().lat().toRad(); var lat2 = marker.getPosition().lat().toRad(); var a = Math.sin(dLat / 2) * Math.sin(dLat / 2) + Math.sin(dLon / 2) * Math.sin(dLon / 2) * Math.cos(lat1) * Math.cos(lat2); var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a)); var distance = Math.ceil(R * c * 1000); $('p').html('The distance between the two addresses is:' + distance +'m'); }); }); }); if (typeof(Number.prototype.toRad) === "undefined") { Number.prototype.toRad = function() { return this * Math.PI / 180; } } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;h1&gt;Distance polyline between two street addresses&lt;/h1&gt; &lt;hr/&gt; &lt;p&gt; &lt;/p&gt; &lt;hr/&gt; &lt;div id="map-canvas" style="width:500px;height:500px"&gt;&lt;/div&gt; &lt;/body&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
