I have a DIV on a page that I want to update with information from an MS SQL Server every five seconds. Would it be better to create my countdown timer on the JavaScript or C# side?

问题 I am an amateur ASP.net developer working on my first job (a friends website). ASP.net v4.0, using VS2010. His company makes 3D models (using a 3D printer). The website is currently in development but can be found here. I would be the first to admit that the code has been a bit rushed and hacked in, but my friend is quite happy with what he has so far.

WebMethod vs ScriptMethod

由 家住魔仙堡 提交于 2019-12-17 15:29:36
问题 I have a .NET 3.5 aspx place with a method marked with the [WebMethod] attribute. I'm calling this with jQuery, sending JSON in both directions. This all works great.
