问题 After reading from many different sources, I am very confused about how View and Model should communicate in the MVC pattern. To my understanding, the accepted answer of this post and this article from Apple are saying the communication of the two should be done through controller. While the MVC page in Wikipedia, the ASP.NET MVC page, and this article in MSDN are showing there is a direct association between View and Model. So according to the answer in here, what the article from Apple is

问题 Edited to make the question more clear. I am trying to work with Isolates (or Web Workers) in Dart. The only ways I can find to communicate between the main and isolate threads are send and call & then from the main thread. But that's a nice way for the main thread to pass some data to the isolate. What's if I want the isolate to be the one who generates information? Like a game engine that does all the physics in a worker and then sends an updated world information to the main thread? In

问题 i've an html page (main.html) opening a new tab in the same domain using javascript with window.open("newtab.html") method. In the new tab users do something ending his activity clicking a button. At this point I would like to send a message to the opener window. I tried with postMessage but from new tab I can't have a reference to the opener. From new tab I'd like something like but I've "ko" var w = window.opener; if (w) { w.postMessage("hi", "http://10.150.10.43"); } else { alert("ko"); }

问题 I'm turning a piece of a non-angular web page into an Angular version by angular.bootstrapping it with an Angular module. It works great except for the fact that it needs to communicate with the other parts of the page. Unfortunately I cannot convert the rest of the page to Angular at this time. The best way I've figured to do this so far is by firing vanilla JS events on the bootstrapped element containing the information I need to communicate. Are there established patterns or better ways

问题 I have a broadcast receiver which is listening to the WifiManager.SCAN_RESULTS_AVAILABLE_ACTION. In that receiver I filter all the available networks and return a list of networks with a specific SSID. I nned to pass that list back to the MainActivity of my application. I know I can create an inner class for my Broadcast receiver but I prefer to create a separate class for better organization. I am thinking in creating a static variable in my mainActivity class and then set that value. Is

问题 We all know that there's a big sweet piece o' binary named http.sys kernel-mode driver in our Windows that does HTTP handling for us. That is basically all we know about it. But today I thought: hey, all our networking stuff like TCP/IP and whatnot is here, in userland -- ws2_32.dll's providers (in mswsock.dll) and all its friends. Since there are userland components, there is no way http.sys uses them. The question is: how do they do it? Any informative links will be greatly appreciated. 回答1
