阅读更多关于 Communicating between Chrome DevTools and content script in extension

问题 (I have already read this and it didn't work, and I've done a lot of searching and experimentation to no avail.) I am writing a Chrome extension (BigConsole) with the goal of building a better Console tab for the Chrome developer tools. This means I would like to execute user-inputted code in the context of the page with access to the DOM and other variables on the page. To do this, the communication is structured as follows: devtools creates a panel where the user writes code When the user

Google Chrome Extension Crashes When Installed From Webstore - Need To Identify Cause of Crash

阅读更多关于 Google Chrome Extension Crashes When Installed From Webstore - Need To Identify Cause of Crash

I have a google chrome extension that crashes after you install it from the webstore. When installed from a local copy the extension does not crash. The crash happens when you click the tool bar icon that is added once it has been installed. The icon is supposed to load a table with URLs. Once restarted all you get is the option to recover tabs. I was hoping someone could help identify the issue of the crash or tell me how to access a crash report to see what is causing the problem. The extension is located here: Chrome Store App Any help or direction will be very appreciated. Thank you I've

Chrome inspector console does not work with version 54.0.2840.99

阅读更多关于 Chrome inspector console does not work with version 54.0.2840.99

I use node-inspector to debug JS with Chrome version 54.0.2840.99. I enter "node-inspector" in one windows cmd console and "node --debug-brk l:\dev\debug\test.js" in another windows cmd console. Open "http://127.0.0.1:8080/?ws=127.0.0.1:8080&port=5858" in Chrome. It's able to debug as usual. But I input "1 + 2" in Chrome console, press "Enter" , nothing happen. I would expect "3" is output to Chrome console. It did work with Chrome version 48.0.2564.116. I did not test with other Chrome versions. Is it a defect of the new Chrome versions? How to resolve the problem? I captured the pictures as

How to dock chrome developer console on the LEFT?

阅读更多关于 How to dock chrome developer console on the LEFT?

问题 I'm aware you can click the vertical ellipsis button ( ⋮ ) and then choose to dock on the bottom, right or detach. But does anyone know how to dock on the left? Currently I have to detach and then manually resize and adjust, which is annoying. Edit: I'll just leave this question open until someone either convinces Google to add left docking, or someone figures out a hack/finds or builds an extension to get it to work. Edit 2: Issue solved. Google just added this in latest standard Chrome

Chrome: this extension loaded itself too frequently

阅读更多关于 Chrome: this extension loaded itself too frequently

I’m building a custom Chrome extension. Sporadically my extension shows this message. This extension loaded itself too frequently What does this mean? Maybe I’m exceeding some threshold which disables the extension? You've called chrome.runtime.reload too often. Chrome considers a reload a "fast reload" when you call chrome.runtime.reload within ten seconds after loading the extension. When your extension triggers more than five "fast reloads", then the following warning will be shown in the UI: This extension reloaded itself too frequently. 来源： https://stackoverflow.com/questions/29086691
