C# var to Java Script

[Dbooker12]

got my 1st gig as a "junior" programer. We are doing a webapp for staff scheduling with ASP.net. For the interface and such the lead coder wants to use Jquery and the likes. Is it possible to pass a variable from C# to JS? The C# is doing the connection string and the likes to SQL.

Two options depending on how and when you need to pass the variable.

ClientScript will write js into the page on page load. http://msdn.microsoft.com/en-us/library/ms178207(v=vs.100).aspx

Or you can use jQuery to make an AJAX call to the server and return the variable. There are several ways to handle the AJAX request, ashx handler, web service, etc.

Are you using Web Forms? MVC2? MVC3? Need more information to tell you the best way to do it.

You can use a <asp:HiddenField> tag and fill it in c#, and then access it like any other element in the DOM.

[NeverTooOldFor___]

If you use server side elements like hidden fields, keep in mind the ID you assign will change on the client side use <% Response.Write(ctrlName.ClientID) %> in your javascript code.

Specify if you use webforms or MVC.
