在ASP.NET WebForms中将服务器变量传递给客户端的正确方法

Question

In the past, I usually have just embedded the values I need passed into html data elements and then read them from there via JavaScript. However, I know there's a more proper way to do so. In particular, I'd like to learn how implement the first method mentioned in this blog post . However, I'd also like to know what the best way to pass data from server-side to client side is when you're not using ajax.

EDIT: Since I'm still pretty unsure, let me explain what I'm trying do to. I'm creating a page with a lot of dynamic content on it that is dependent on reading from a database. I want to be able to load the page's static content first. Then, using jQuery, I want to make an ayschronous HTTP get request to the server to read from the database and retrieve the information I need. Finally, if I need more information from the database, I want to be able to request the server for more information without having to reload the page.

Answer 1

"When you're not using ajax"!?!? - Start!

If you're dead set on not making a service request to the server, there are the following ways:

Hidden form fields - so <input type=hidden value=xyz >

PageMethods - ok this is ajax, but it's simple, see here http://aspalliance.com/1922_PageMethods_In_ASPNET_AJAX.2> http://aspalliance.com/1922_PageMethods_In_ASPNET_AJAX.2

Best way.... is to do it properly, implement webapi and send down JSON then on the client end interpret that with Javascript.

Edit: your edit paints a different picture. I thought you just wanted a single piece of data, but it sounds like you need a proper api, so go with webapi, and use jQuery to make the calls, then populate through code, or jQuery templates(the best option).
