Viewcomponent alternative for ajax refresh
On beta7 it is now possible to return a ViewComponent directly from a controller. Check the MVC/Razor section of the announcement
The new ViewComponentResult in MVC makes it easy to return the result of a ViewComponent from an action. This allows you to easily expose the logic of a ViewComponent as a standalone endpoint.
So you could have a simple view component like this:
[ViewComponent(Name = "MyViewComponent")]public class MyViewComponent : ViewComponent{ public IViewComponentResult Invoke() { var time = DateTime.Now.ToString("h:mm:ss"); return Content($"The current time is {time}"); }}
Create a method in a controller like:
public IActionResult MyViewComponent(){ return ViewComponent("MyViewComponent");}
And do a better job than my quick and dirty ajax refresh:
var container = $("#myComponentContainer");var refreshComponent = function () { $.get("/Home/MyViewComponent", function (data) { container.html(data); });};$(function () { window.setInterval(refreshComponent, 1000); });
Of course, prior to beta7 you could create a view as the workaround suggested by @eedam or use the approach described in these answers
