问题 I have a puppeteer script I run to reboot my modem. It has worked for I guess about a year with no problem. 5 days ago it stopped working. I was looking into it and realized that I am getting errors I didn't used to get when running it and the script fails. The thing is I didn't change anything. As far as I can see, the HTML hasn't changed either yet it is failing. So I wonder if there is a bug in chromium or puppeteer or if it handles things differently somehow? Here's a codepen with https:/

问题 I am experimenting with the V8 engine. In V8 (full-codegen-x64.cc) exists this function for comparing types: void FullCodeGenerator::EmitLiteralCompareTypeof(Expression* expr, Expression* sub_expr, Handle<String> check) So, if for example: typeof Obj == "object" Then sub_expr is an Expression object with "typeof Obj" and check is an "object" . How can I get a JSObject from an Expression object, if possible? - not possible (You can't. An Expression is a piece of syntax Andreas Rossberg) In

问题 We have integrated Chromium Embedded Framework into our Windows game to allow us to render web pages from within our application, and everything works fine, except MP4 videos. I understand Chromium does not include this codec due to licensing issues, but can anyone provide details on how we can add support, even if we have to license a codec for it. All the information we can find seems to be old, and the functions referred to appear to be deprecated... so we are at a bit of a loss. All the

问题 I am using the remote debugger inspector by visiting for example: http://localhost:9222/devtools/inspector.html?ws=localhost:9222/devtools/page/33767d5c-6abf-4c79-b8e7-d3b0c251fcaa The inspector works other than not being able to copy within the element, for copying xpath/sizzle selectors for instance which is really important . But on copy I am getting: Clipboard is not enabled in hosted mode. Please inspect using chrome://inspect I am remote debugging using an "external" inspector in google

问题 I'm trying to get a list in JavaScript (not using jQuery) of all the elements on the page with a specific class name. I therefore employ the getElementsByClassName() function as follows: var expand_buttons = document.getElementsByClassName('expand'); console.log(expand_buttons, expand_buttons.length, expand_buttons[0]); Note that I have three anchor elements on my page with the class 'expand'. This console.log() outputs [] 0 undefined Next, for kicks, I threw expand_buttons into its own array

问题 I'm trying to use SKIA for drawing on Windows. Is there anyway to initiate SkCanvas from HDC ? 回答1: There are several approaches "to use" skia on Windows. These approaches described in the SkOSWindow_win.cpp at the skia\src\views\win in your skia folder. For example: You can attach OpenGL viewport to your window as it has been done in function SkOSWindow::attachGL HDC dc = GetDC((HWND)fHWND); if (NULL == fHGLRC) { fHGLRC = SkCreateWGLContext(dc, msaaSampleCount, kGLPreferCompatibilityProfile

问题 I am working on an Electron app and need to enable the following Chromium flag GuestViewCrossProcessFrames to make scaling work with webview. I tried calling the following line in my main.js but it doesn't seem to work. Also tried enabling plugins for the BrowserWindow as well as webview. app.commandLine.appendSwitch('--enable-features=GuestViewCrossProcessFrames'); Can someone help me setting up this flag? Thank you. 回答1: you can set by calling const { app } = require('electron'); app

问题 I want a standalone JavaScript library for embedding. I already build V8 and its working correctly, but binary needs two "external data" files. I don want this files. I was trying to build V8 without "external startup data". I tried to set v8_use_external_startup_data : 0, in build.common.gypi and build/standalone.gypi, but then make is reporting failure at some point. I'm using following code to build v8: git clone https://chromium.googlesource.com/chromium/tool/depot_tools.git export PATH=
