How to force Chrome debugging tools to debug in pretty code?

由 两盒软妹~` 提交于 2019-12-03 06:32:46
问题 Although I used pretty code and had set up the breakpoints in "Pretty code" tab, debugger keeps working in minified code. (I can't see exactly where I am and need to continuously switch between source and "pretty code"). On same pages with same script it sometimes work and sometimes don't. I can't find the cause or any difference in the way I activate it. Is there any way to force debugger to use "pretty code"? Any Ideas or additional questions? Should this be reported as a bug? EDIT: I still

Chrome developer tools - Network - how to filter only POST and PATCH requests?

问题 In Chrome browser - Chrome developer tools - Network - I can show only POST requests by putting "method:POST" in the Filter editbox. What filter should I use in order to see both PATCH and POST requests? Thanks 回答1: Filter option is quite powerful but it's limited to only using AND (conjunction). So simple workaround would be to use negatives... For instance in your case you could create filter like this: -method:GET -method:OPTIONS -method:PUT This should filter out most of the requests. If

问题 I'm building a web application which uses CORS to communicate with it's server. This means that every request is preceded by one with OPTIONS method. Is it possible to filter those out in inspector? It makes a lot of unnecessary clutter on network tab. 回答1: Yes, you can use -method:OPTIONS in the filter of the Network panel to show all methods apart from ones with type OPTIONS . If you omit the preceeding - , it will only show methods of type OPTIONS . Example Before: After: You can read more

Can you inspect a webapp's filesystem from the chrome dev tools?

由 自闭症网瘾萝莉.ら 提交于 2019-12-03 06:09:10
I am working on a website that is using HTML5's Filesystem API to write some files to a temporary file system. Is there any way I can use the Chrome Developer tools to inspect the files I have written? If you go to chrome://flags and enable "Enable Developer Tools experiments", then go to the Experiments tab in the Dev Tools settings, there's one named "FileSystem Inspection" that might work. I haven't tried it, though. Filesystem inspection is no longer available . I couldn't find an official announcement, but it looks this filesystem API is going to be soon deprecated by Chrome as it was

What do the colours mean for detached DOM nodes in the Chrome Heap Profiler?

由 天大地大妈咪最大 提交于 2019-12-03 05:41:41
When analyzing heap snapshots using Chrome devtools, I can't seem to figure out what the colours mean when viewing Detached DOM Trees. What is the difference between red & yellow? ŁukaszBachman There is a good explanation available here . From the article: Red nodes do not have direct references from JavaScript to them, but are alive because they’re part of a detached DOM tree. There may be a node in the tree referenced from JavaScript (maybe as a closure or variable) but is coincidentally preventing the entire DOM tree from being garbage collected. Yellow nodes however do have direct

问题 Reference: Using the new code snippets feature in google chrome I am using the code snippets in google chrome, so say I have a snippet file. check_consistency.js Is there an api or a global object through which we can run the snippet directly from the command line, something like: window.runSnippet('check_consistency.js') or maybe call methods defined in the snippet directly. 回答1: Workflow Tip 1 I also want to see this functionality added. Meanwhile, perhaps try opening the Sources where (as

Where has the Google Chrome Console Filter [_] Regex checkbox gone?

由 别来无恙 提交于 2019-12-03 05:35:52
All of the Google Chrome Console documentation pages (and numerous SO answers) show a checkbox labeled "Regex" next to the filter when the filter bar is expanded, e.g., from the Command Line API Reference : I use it so much that I have macros set up to paste various Regexes into it, so I'm positive I am not crazy and that it existed until very recently. I am using Google Chrome Version 57.0.2987.21 beta (64-bit) on Mac OS X, and it's no longer there: Is it gone, have I done something inadvertent to hide it, or what? Update: This might be a bug in the Beta channel: DevTools: [regression]

How to get the output from console.timeEnd() in JS Console?

由 Deadly 提交于 2019-12-03 05:26:07
问题 I'd like to be able to get the string returned from console.timeEnd('t') in my Google Chrome Javascript Console. In this example below, I'd like one variable which would contain "t: 0.276ms" > console.time('t'); console.timeEnd('t'); t: 0.276ms < undefined Is this something doable? 回答1: In Google Chrome 23.0.1262.2 (Official Build 155904) dev, it looks like it's impossible. The only way I found to be able to calculate time with accuracy is to use window.performance.webkitNow() Here's a simple

Chrome DOM breakpoint keeps enabling itself

由 我只是一个虾纸丫 提交于 2019-12-03 05:25:56
问题 Yes, in the console, I made the horrible mistake of setting a DOM breakpoint on an element that wasn't getting the content injected into it that I expected it to. Well, now whenever I load that page, the breakpoint triggers. I uncheck the box next to it. It comes back. I right click on it and click "Remove Breakpoint." It disappears from the list, and seems to work fine until the next hard refresh, then BAM breakpoint. I click the disable all breakpoints button. It once again works until the

Chrome Dev Tools Issue With ES6 String Literals/Typescript

由 [亡魂溺海] 提交于 2019-12-03 05:25:22
问题 I am working on a project using Typescript and some of the ES6 features exposed by Typescript like ES6 String Literals e.g. `Something ${variable} Something else` . Whilst debugging a problem I dropped a breakpoint into my typescript file to step through it in the source panel, which usually works fine. But Chrome Dev Tools has an issue with ES6 String literals and doesn't seem to recognise the end of an ES6 String literal. Instead all code following the string literal is marked red (string
