overriding

问题 A webpage is setting a built-in javascript method to null , and I'm trying to find a way to call the overridden methods in a userscript. Consider the following code: // Overriding the native method to something else document.querySelectorAll = null; Now, if I try to execute document.querySelectorAll('#an-example') , I will get the exception Uncaught TypeError: null is not a function . The reason being the method has been changed to null and is no longer accessible. I'm looking for a way to

问题 I'm trying to override the WebSocket.send() method. My objective is being able to fuzz the sent data to test robustness of the server implementation. I'm adopting this approach: // OVERRIDE WEBSOCKET SEND METHOD WebSocket.prototype.oldSend = WebSocket.prototype.send; WebSocket.prototype.send = function(data) { console.log("ws: sending data"); WebSocket.prototype.oldSend(data); }; This fails when the WebSocket.prototype.oldSend(data) command is called the first time, with the error: Failed to

问题 I have created a 'template' project A which has 10 controllers ( partial class ). All these controllers are packed in a nuget package and are consumed by projects B, C & D. The nuget generates the controllers in the folder controllers/_core so they are nicely stored separately. The nuget package does not have a reference to the dll of project A. Now to get down to the problem; It could be that one of the controllers that are generated need to be modified. By adding a second partial we could

问题 I have one abstract class -let's say myBase. And I want all the classes derived from myBase to have one static field called public static List<string> MyPArameterNames { get {return _myParameterNames;} } So, every child class can tell what parameter names it uses; I want static because I do not want to create an instance just for this. How can I achieve this? 回答1: You can't do that. Interfaces, abstract, etc. cannot apply to static members. If you want to accomplish this, you will have to

问题 I'm trying to get rid of max-width that present in the theme. This is what I see in Chrome (and if I uncheck it, it does what I need): @media (min-width: 1280px) .MuiContainer-maxWidthLg { max-width: 1280px; } How can I do this? I tried something like this: const useStyles = makeStyles(theme => ({ root: { '& .MuiContainer-maxWidthLg' : { maxWidth: //No matter what I put here, it does not work }, but it does not seem to have any effect... How can I override this? Thanks, Alex 回答1: The maxWidth
