Net control to send data from server to client side.
A single-page application (or just a few-pages application) downloads from the web server as an empty DIV element.
All the remaining content is inserted dynamically after placing additional HTTP requests for JSON data.
When you click “Get session value” button, the session value is got and placed in textbox.
Of course, users can view this data to viewing the source of the page.
Ajax technology and JSON makes this partial-rendering easy. NET's own partial-rendering techniques, returning HTML. It requires less client-logic and is quicker to implement. By ‘classic web sites’ mean web sites where the vast majority of pages are being served entirely from the web server and fully refreshed after each postback.
In the real-world, or at least in the section of the real world that I see every day, there are still plenty of classic ASP. The full refresh of the page after a postback can be significantly slow and cumbersome for users, especially when the use of graphics of these sites is quite heavy.
Such data is then incorporated in the current DOM via HTML templates and libraries such as Knockout or Angular JS.
You can also use j Query to place a POST request and receive back a plain ack message or some JSON data.
In this context, posting a form is merely a Java Script-driven request.
