Making cross domain call using JSONP (JSON with padding)

Hi,

Just created a simple html page that uses JSONP to make cross domain call to twitter’s API.

Source Code:-

<!DOCTYPE html>
<html>
<head>
    <title>JSONP Example</title>
    <script>

        function getTweets(tweets) {

            var tweetDiv = document.getElementById("tweet");

            for (var i = 0; i < tweets.results.length; i++) {
                var tweet = tweets.results[i];

                // create div element for each result
                var div = document.createElement("div");
                div.innerHTML = "<img src= " + tweet.profile_image_url + "></img> ";
                div.innerHTML += tweet.from_user + " : <b><i>" + tweet.text + "</b></i>";

                // append it to tweet div
                tweetDiv.appendChild(div);
            }
        }
    </script>
</head>
<body>
<div id="tweet">
</div>
<!--Specifying search term and callback function-->
<script src="http://search.twitter.com/search.json?q=Sachin%20Tendulkar&rpp=10&callback=getTweets"></script>
</body>

Used HTML 5 Geolocation API with Bing Map.

Just created a simple html page that shows my location using the new Geolocation API.

Source Code:-

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>Geolocation HTML5</title>
    <script src="http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2"></script>
    <script>

        window.onload = getMyLocation;

        function getMyLocation() {

        // Check if the browser supports the Geolocation API
            if (navigator.geolocation) {

                // we can specify how the geolocation computes its value
                var postionOptions = { enableHighAccuracy: true, timeout: 5000, maximumAge: 0 };

                // call getCurrentPosition method of the API
                // getCurrentPosition(successHander, errorHandler, positionOptions)
                navigator.geolocation.getCurrentPosition(displayLocation, displayError, postionOptions);
            }
            else {
                alert("No geolocation support in the browser");
            }
        }

        function displayLocation(position) {

            // load map if location is found
            map = new VEMap('myMap');
            map.LoadMap(null, 4, VEMapStyle.Hybrid);

            // get the latitude and longitude
            var latitude = position.coords.latitude;
            var longitude = position.coords.longitude;

            // place the pushpin
            PlacePushPin(latitude, longitude);

            // get location div and show the latitude longitude and the accuracy
            var divLocation = document.getElementById('location');
            divLocation.innerHTML = "I am at Latitude :" + latitude + ", Longitude : " + longitude;
            divLocation.innerHTML += " with " + position.coords.accuracy + " meters accuracy";
        }

        // place the pushpin in the map for the location found

        function PlacePushPin(lat, lon) {
            latlong = new VELatLong(lat, lon);
            myPushPin = new VEShape(VEShapeType.Pushpin, latlong);
            map.AddShape(myPushPin);
            map.SetCenterAndZoom(latlong, 15);
        }

        // error handler
        function displayError(error) {

            var errorTypes = {
                0: "Unknown Error",
                1: "Permission denied by user",
                2: "Position is not available",
                3: "Request timed out"
            };

            var errorMessage = errorTypes[error.code];

            if (error.code == 0 || error.code == 2) {
                errorMessage = errorMessage + " " + error.message;
            }

            var divLocation = document.getElementById('location');
            divLocation.innerHTML = errorMessage;
        }
    </script>
</head>
<body>
    <div id="location"></div>
    <div id='myMap' style='position: relative; width: 600px; height: 250px;'>

At times we have got this error while saving our record in CRM. It can occur if we have mistakenly registered steps of one of our plugins to some other plugins. Please check in plugin registration tool and delete those steps.

Hope it helps.
