问题 Overnight, my originally working react service was disabled. The reason that it happens is my browser or react server stopped supporting this react component "react-selectize". React-selectize is a react component build on "react-select" and provide some extra feature. The DOM no longer update for the component. A quick fix would be to change component into react-select and abandon some features. My question is, we didn't update our browser or any npm package, why would this change occurs

问题 As a sub-question to this, I want to know, since Qt5 is distributed with full source code, is it possible to set up debugger break-points inside Qt itself ? Is there a symbol file shipped with Qt5 for the binary build? Do I have to build my own Qt to do this? What is the fastest way to have breakpoints inside Qt5 working with QtCreator on Ubuntu? 回答1: You need to configure and build qt yourself with debug symbols. ( -debug ) Then in QtCreator you can go to Options > Debugger > General and "

问题 I've created a basic Vue.js app from VS2017 template. Everything is working, but I cannot debug any code. Could You explain why this happens and is there any workaround? debugger 回答1: Vue is a front-end framework, which means it runs inside a browser, not locally (NodeJs). The best way to debug Vue.js application is to install a VueDevtolls from chrome's app store. Install this, it will help you accelerate your development process. On a component you want to debug with, right click inspect,

问题 I am unable to find any tools within QtCreator that would allow me to debug std::function calls and determine what's happening inside. Is it possible to "step into" std::function ? In case it is possible, how do I set it up, because a strait-forward approach (i.e push "step into" button when paused on the corresponding std::function execution call) does not work. 来源： https://stackoverflow.com/questions/51589796/qtcreator-debugger-step-into-stdfunction

问题 I have a javascript code: newDate: function(days) { var newDate = new Date( parseInt(startDate) + 1*1000*3600); var date = newDate .getDate(); return date ; }, Seems like this is the part of the program that produces different results on Android and iOS. All the rest data is the same. How can it produce different results on Android vs iOS? 回答1: The Date constructor is only consistent cross-browser for the following Date formats: "2010" "2010-06" "2010-06-09" "2010-06-09T15:20:00Z" "2010-06

问题 I've been assigned a web app written in VB using VStudio.net 2003. I am trying to configure the source on my localhost (VStudio 2008) so I can explore and learn about the current app (before I begin any real changes) and I cannot get debugging working for the web service project(s). Symptom 1: "Unable to automatically step into the server. The remote procedure could not be debugged. This usually indicates that debugging has not been enabled on the server. See help for more information". This

问题 When I run node --inspect app.js it says "Debugger attached". Then I open up chrome://inspect and I see my app running there so I click either Open dedicated DevTools or Inspect (next to the app's name). No matter how I open Node DevTools though, it just doesn't seem to be connected to anything (I can't see the source code there, the debugger statements are ignored, nothing logs to the console etc). I also tried opening it by opening regular DevTools and clicking the green Node icon. It's

问题 I've a simple table with an integer column: # setup table: create table t(x int); insert t select 1; The query select round(1.234, 1) from t returns 1.2 as expected. However, select round(1.234, x) from t returns 1.2000 . (It should return 1.2 , as per the docs.) Is this a bug? (Tested on version 5.5.10 and latest 5.6.24.) Or, is there any particular technical reason why columns cannot be used in the second argument of round ? How can we get round to work even while there are columns used in

问题 The question speaks for itself but I will try to clarify more. after make my http request through the app to connect a local databse JSONObject json = jsonParser.makeHttpRequest(urlCreate, "POST", params); the return of json is being null; this throws a fatal error, crashs my app and it doesnt feeds me back about where or what exactly is the error through the request. I think the error is inside the php file being called with the "urlCreate" parameter, so how can I track and debug the php
