由 六眼飞鱼酱① 提交于 2019-12-04 22:08:16
问题 I want to apply an ActionFilter in ASP.NET MVC to EVERY action I have in my application - on every controller. Is there a way to do this without applying it to every single ActionResult method ? 回答1: Yes, you can do this but it's not the way it works out of the box. I did the following: Create a base controller class and have all of your controllers inherit from it Create an action filter attribute and have it inherit from FilterAttribute and IActionFilter Decorate your base controller class

We've just bought the Wrox book but it's more than a week away from delivery and I'd like to read up on this well before then. Can you also roll your own and is that documented somewhere? 回答1: If you open System.Web.Mvc using Reflector, you

问题 I would like to take an existing action method, render its return value to a string and ship it as a JSON for a response to an AJAX request.

由 心不动则不痛 提交于 2019-12-03 17:09:41
I am trying to use the Struts2 jquery plugin for ajax requests on some of my forms, but I am having an issue with the response to the page. The struts action is validated and executed properly, but when jquery gets a response, it sets the response as the HTML of the entire page... It is putting the response in the correct place, but it is not responding with the right thing at all... Here is the jsp form: <%@ tag language="java" pageEncoding="UTF-8"%> <%@ taglib uri='http://java.sun.com/jsp/jstl/core' prefix='c'%> <%@ taglib prefix="s" uri="/struts-tags" %> <%@ taglib prefix="sj" uri="/struts

What's the point of ActionResult return type?

问题 What is the point of an action returning ActionResult? 回答1: Returning an ActionResult instead of "just doing whatever the ActionResult is doing" (i.e. using Response.Redirect directly or trying to render out a View through the Response OutputStream directly) gives you one really nice advantage: Unit Testing is really easy on that, especially since you normally do not need a web server to unit test MVC Projects. Addendum: As an example for a redirect: If you do return Redirect(newUrl); in your

Define your link as an Ajax action link and specify the ID of a spinning GIF somewhere on your page. <div id=
