Spelling Champion is the first app written by my former colleague Peter Lu. It makes clever use of the voice API, reading a word and a sample sentence using that word; then asking the student to spell the word with his or her keyboard. It keeps track of right answers and offers a second chance if you get it wrong. The words are simple and aimed at beginning readers.

When I first saw the app, my only criticism was a lack of pictures, which I felt would help to draw the interest of a young child. Peter promised to add this in his next release.

There is a free version and a paid ($2.99) version. The paid version includes many more lessons than the free version.

You can download Spelling Champion from this link and you can read details about the app at http://spellingchampionapp.blogspot.com

TechReady is an internal conference for Microsoft field employees. As far as I can tell, field employees are those who do not work for a product team in Redmond, which is still a lot of people.

Well, I am now a Microsoft employee and my group (Developer Platform Evangelism, aka DPE) does not build products, so I was able to attend TechReady for the first time this week.

What an experience! I attend a lot of conferences and my habit at these conferences is to only attend a few sessions, electing instead to find smart people in the hallways or speaker room or lunch room and pick their brains to learn as much as I can about real world software experiences. This conference was different - in part because I didn't know a lot of attendees and in part because so much of the content was not available anywhere else.  I attended as many sessions as I could and even watched recordings of a few sessions on the flight home.

Before attending, I promised I would not share the content of any sessions (much of it focused on features that may or may not be in a future product release); so I'll share my impressions and experiences here.

First, this conference was a great opportunity to meet others inside Microsoft. A number of evangelists from the west region attended and I got to know them. One night, my team had dinner with Sanket Akerkar, the Vice President in charge of US DPE. I was impressed with his openness and the frank exchange about the future of evangelism within Microsoft.

At most meals, I sat with strangers and got to know people from all over the world in many different roles at Microsoft. Microsoft is a very diverse company with all kinds of people doing all kinds of things and this week really underscored that fact to me. I also had a chance to meet up with some old friends, such as Josh Holmes, Kevin Pilch-Bisson, Dani Diaz, Chet Kloss, Mark Grimes, Jeff Wilcox, and Ted Neward. Ted doesn't work for Microsoft but he invited me to dinner with his family when he heard I was in town. I had a long conversation with consultant David Chappell, a Microsoft consulting partner who has written extensively on the impact of the cloud on businesses. Part of that conversation was recorded and I'll share it in a few weeks.

I heard a lot of talk about technologies that I want to explore later - in particular Project Siena and Unity.

I listened to many people smarter than me discussing product feature decisions. I was impressed by how much of Microsoft product features are driven by customer requests. A frequent exchange I heard was: "Why did you decide to implement Feature A and not Feature B?" "Because many of our customers have requested Feature A and we hear very little demand for Feature B, so we deferred B for a later release." Microsoft is sometimes perceived as a walled tower that unilaterally pushes products on customers but this week showed me emphatically that is not the case.

Overall TechReady gave me a greater appreciation for my new company. The conference is bi-annual, so I hope to get back to it shortly.

Ajax refers to the pattern of calling server-side methods from client-side JavaScript. jQuery provides a simple, straightforward method for making Ajax calls. The syntax is

$.ajax({
            url: ServiceEndpoint,
            dataType: ReturnDataType,
            type: HttpVerb,
            data: Data,
            error: function (err) {
                // Code to run when error returned
            },
            success: function (data) {
                // Code to run when successfully returned
            }
          });

where

  • ServiceEndpoint is the URL of the method to call on the server
  • ReturnDataType is the data format we expect the server method to return (“xml”, “html”, “script”, “json”, “jsonp”, or “text”). You can specify multiple values and the server will return the first matching format type that is supported by this method.
  • HttpVerb is the HTTP verb (“GET”, “POST”, “PUT”, or “DELETE”) to use to send data to the server.
  • Data is the data (if any) that is sent from the client to the server.

By default the Ajax method executes asynchronously. When a call returns from the server, jQuery will run the function specified in the success parameter (if the call returned successfully); or the function in the error parameter if an exception occurred. These functions accept return data or error information returned from the server as parameters, so that your client-side code can handle return values effectively.

Ajax can provide a much more responsive experience to your web page and jQuery can make ease the process of making Ajax calls.

In the last article, I showed how to use jQuery to select elements in the Document Object Model (DOM) of a web page. In this article, I will show things you can do with those selections.

Calling Methods on Selections

We can call methods on the list of objects returned by a selection simply by appending a dot, followed by the method call and any arguments to the selection syntax. For example, the following jQuery will hide all the anchor tags on a page:

$(“a”).hide();

Binding Functions to Selections

One of the powers of jQuery is the ease with which we can bind a function to the events of an object, so that this function executes whenever the event fires. To do so, simply append a selection with a dot followed by the name of the event; then, pass the function as an argument to the event, as shown below:

$(selection).eventname(function(){
…
}

For example, the click event fires when a user clicks on a page element. The following sample binds a function to the click event of an element with the ID “Div1”:

$(“#Div1”).click(function(){
…
}

The (document).ready event

The document variable is defined within the jQuery script. Selecting this variable with $(document) will return the document as a whole. The most common use for this selector is to bind a function to the document’s ready event. The syntax for this is

$(document).ready(function(){
    …
});

I have omitted the body of the function in this case, but notice the anonymous function declaration. In JavaScript, we don’t need to assign a name to a function if we are binding it to an event – we only need to pass that function to the method name. This is common syntax in JavaScript.

In fact, binding a function to the document ready event is so common, that its syntax can be shortened to simply surrounding a function with parentheses preceded by “$”, as shown in the following snippet, which does the same thing as the previous snippet

$(function(){
    …
});

Putting it All Together

We can nest functions in jQuery and we often do so by binding code to events when the document.ready event fires, as in the following example:
<script type="text/javascript" src="jquery-1.10.2.min.js"></script>
<script type="text/javascript">
   $(function(){
    $(“#HideTextDiv”).click(function(){
     $(“#Div1”).hide();
    });
    $(“#ShowTextDiv”).click(function(){
     $(“#Div1”).show();
    });
   });
</script>

In this article, I showed how to manipulate selected elements and bind events to those elements. This can be done when a page loads by adding code to the document.ready event.
