How to disable chrome extensions JS when debugging in devtools?

阅读更多关于 How to disable chrome extensions JS when debugging in devtools?

问题 When I add mouse event breakpoint, devtools always jump into extension's JS. Is there any way to point to my mouse event code directly? 回答1: I think the simplest way is to open an incognito window ( Ctrl-Shift-N ) (or Cmd-Shift-N for mac) and debug in there, because then there will be no extensions loaded (by default). I know what you mean by this question: when debugging, and doing something simple like pausing execution, you always find it breaks into one of the extension's codes instead of

How to highlight elements in a Chrome Extension similar to how DevTools does it?

阅读更多关于 How to highlight elements in a Chrome Extension similar to how DevTools does it?

I'm interested in creating a Chrome Extension which lists all the elements on the webpage that have an 'id' attribute in a menu. Then, when the user clicks on the element in the menu, the corresponding element on the webpage is highlighted. I saw Chrome devtools highlights an element when you right click and inspect on it. I'm curious if there is some highlighting API accessible from DevTools? If not, how does one highlight elements similar to how devtools does it? Chrome API does not provide access to such highlighting; you'll need to implement it yourself with an overlay. Chrome API does

How to show mouse pointer in responsive mode?

阅读更多关于 How to show mouse pointer in responsive mode?

问题 I used to be able to uncheck a checkbox that said Emulate touch screen in the Emulation/Sensors -panel so that I could see a mouse pointer when using responsive mode. This panel is now gone, and the new sensors-panel doesn't have this setting. This makes it impossible to use the responsive mode, as I have no pointer and no control where I touch/click (who designed this feature?!). How can I see a pointer/mouse when I use responsive mode in newer Chrome? 回答1: Apparently, you're supposed to see

阅读更多关于 What does “connecting” mean in Chrome Developer Tools in the Network Tab, and why does it show up only for some sites?

I've been trying to look for an explanation online but I can't seem to find one. If you go to a site like youtube.com on Chrome and hover over the blue bar corresponding to the file name "http://www.youtube.com/", you'll see four different things: -Blocking -Sending -Waiting -Receiving While viewing a different site's page in the network tab, I see -DNS Lookup -Connecting -Sending -Waiting -Receiving It takes a long time to do all these things, even though the page is so simple. What makes my server display different statistical keys for a page load, and what can I do to optimize? In general,

Chrome DevTools save CSS changes directly to SASS file

阅读更多关于 Chrome DevTools save CSS changes directly to SASS file

问题 Is it possible to have style changes done directly in the "Styles" panel not only persisted to the .css but also to the corresponding .scss file? I have CSS source maps for every file and that works fine - I can jump right into the .scss file when I Ctrl-Click a property. I can edit the .scss file then and it reloads correctly (compass task in the background), but unfortunately everything I change directly in the Styles panel is persisted only to the compiled .css file. As soon as I change a

Debugging with chrome with es6

问题 I am trying to use Ecmascript 2015 for my project and I am finding it hard to add breakpoints at specific places (places I thought was logical to have a breakpoint). I have #enable-javascript-harmony flag in chrome set to true (if that helps), but I am using babeljs to transpile and have sourcemaps to directly set breakpoints in the file that I want to debug. I am most certain that I am doing something wrong but can somebody point me where I am making mistake. For reference I have added a GIF
