Revealing Module Pattern in JavaScript


Revealing Module Pattern makes the code to read better and more structured way, This really useful when we had to repeat the name of the main object when we wanted to call one public method from another or access public variables. This is done by adding a return statement at the end of the function that exposes the public members.

The benefits of this approach are. The Revealing Module Pattern allows the syntax of your script to be fairly consistent - it also makes it very clear at the end which of our functions and variables may be accessed publicly, something that is quite useful. In addition, we also able to reveal private functions with more specific names if we wish.

The following code demonstrates how the module can be revealed.
var myModule = (function () {
 
    var name = 'Mohamed Rafeeq';
    var age = 28;
 
    function updatePerson() {
        name = 'Mohamed Rafeeq Updated';
    }
    function setPerson() {
        name = 'Mohamed Rafeeq Set';
    }
    function getPerson() {
        return name;
    }
    return {
        set: setPerson,
        get: getPerson
    };
} ());
() –> Indicate the self invoking, this act as singleton call to myModule.
This can be called as below

myModule.get();

DD4TFormRouteHandler (posting a form as tridion page url)

ASP.NET routing enables us to use URLs that are not physical files, In DD4T we have the default page route definition. In which all page request redirct to Page controller and process the page. DD4TFormRouteHandler is a custom route handler responsible for mapping incoming browser requests to particular MVC controller actions, this works along with  DD4TFormHelper  (that generate the route information for the form) Posting a form in DD4T is not complicated, you can create the mvc form as a normal controller and action, then post it via AJAX. But, when we need to do post the form as normal page, It would need a tweak as the controller/action is not a page existed in tridion. This can be achieved by implementing a custom Mvc RoutHandler and reroute the posted form to the encrypted action and controller. It works as below daigram. So, how to do this. to render out the form we have BeginDD4TForm html helper as below that generate the form with encrypted route values....

Why not to have a static const in c#

This is just a thought, that I was thinking why can't we have a constant with static in C#, and the answer is 'NO'; That we cannot have a static constant; e.g: I created a class as below: public class Constants1 { public const string Const1 = "Hello"; public const string Const2 = "World"; public static string Static1 = "Hello Static"; } When we compile the program into IL, the C# compiler does a magic in IL, that the constants converts into static literals, of course it has to, that's why we are able to access the constants as Constants1.Const1
