问题 I've created a tool in JavaScript that determines the current UTC time and checks if another predetermined date has passed yet. I'd like to change my browser to another timezone and see if the tests still pass but I'm having trouble finding a way to do this. Is there a way to do this in Chrome dev tools? If not, do any other suggestions come to mind? 回答1: To do this in Chrome Dev tools you can use the Geolocation sensor emulation. Go to the 3 dotted menu, More Tools and Sensors. There's a

问题 I have a service worker going fine in Chrome desktop and Chrome mobile, and I can tell exactly what is happening via the amazing DevTools in Chrome desktop (monitoring Chrome mobile remotely via USB). My service worker is based very closely on this example. The page reloads fine without a network connection, and from the Network tab of DevTools I can confirm that resources are being cached and served by the service worker as expected. But I am also loading the same page in a WebView and I'm

问题 I have low FPS when start scrolling. I use DevTool Timeline to find out the reasons for this. But I can't find what means dashed chart. Help me please! 回答1: It means the work is done by a background thread, rather than by the main thread. Take this screenshot as an example. A small amount of code runs on the main thread, followed by most of the rendering happening on other threads. 来源： https://stackoverflow.com/questions/37181979/what-means-dashed-chart-in-chrome-devtool-timeline

问题 In the below image (from chrome performance profiling tab for a API call), what is resource loading which costs 719 ms ? If I visit the network tab, for the same API call, I see only 10.05 seconds. What is resource loading mean here ? Is there any specific activity the browser does after receiving the data ? 来源： https://stackoverflow.com/questions/60972176/chrome-developer-tools-performance-profiling

问题 Let's say I have this function: function test () { // statements 1 statement_X; // statements 2 } I'm stepping trough the statements with the browser's dev tools. Now, when I'm paused at "statement_X", I would like to terminate the function execution (I don't want the "statements 2" part of the function to be executed), as if the "statement_X" is immediately followed by a return; statement. I know that Chrome has inline script editing, so I could manually add the return statement after the

问题 I'm making a local web page (.html) that loads a few .js files and am having trouble using Google Chrome's Developer Tools. Definition The problem I'm having has to do with the Source Panel: I have one source tab open with a specific file and when I open this file by clicking the console or the source file at the left, randomly a duplicate is created instead of just redirecting it to the one already open. Both will have the same file-path: Both will allow me to write and save the file (even

问题 I was testing a website with the Developer Tool of Firefox and I was facing a weird bug. Then I checked the window width with a simple console log console.log($(window).width) and I saw that the reported width in developer tools wasn't the same that javascript was detecting. I tried than with the Google DevTools and showed width was consistent with the console log width. Is this a Firefox bug or am I doing something wrong? Actually on a real mobile device and on Google DevTools the website
