Chrome developer tools window dimensions are inconsistent

由 允我心安 提交于 2019-12-08 20:10:44
问题 When you have the Chrome developer tools open, and you resize the window, a small white box appears in the top right corner telling you the dimensions of the window as you resize it. I've marked it with a big green arrow in the screenshot below. This is a very useful tool, but I've noticed that frequently the values are unexpected and inconsistent with the widths of other elements. For example, when I took the screenshot below, Chrome says the window width is 419px. But if I click the html

Removing DOM nodes with proper GC (no leaks)

由 守給你的承諾、 提交于 2019-12-08 19:04:22
问题 The problem Adding nodes, while removing the old ones from the DOM, doesn't discard the old nodes from memory. (not all of them at least, without apparent reason). How to see this happening (you already know this but anyway..) right click the output area and inspect using Chrome developer tools . Click on the Timeline tab and then at the circle (dot) on the upper left side to start recording. now click on the body element, and it will start adding and removing items every 300ms (the removed

How do I restore console.log() function that has been disabled by a website? [duplicate]

由 倖福魔咒の 提交于 2019-12-08 18:37:26
This question already has answers here : Restoring console.log() (8 answers) Closed last year . UPDATED: The reason the console won't log is the site runs this script: // Production mode // Disable console.log console.log = function() {}; I'm guessing there isn't a way to get the function back on the site? Prior issue: I'm running a script in my Chrome console that follows everyone on a site. There are 200 people on the page, and I want to iterate through all the follow buttons and click them all by running this script in the console: javascript:var inputs = document.getElementsByClassName(

Possible to tell if two objects are the same in Chrome debugger?

由 旧城冷巷雨未停 提交于 2019-12-08 17:47:14
问题 In Eclipse, the debugger shows a unique session id next to each object (for Java and AS3, anyway). This makes it simple to identify the same object appearing in multiple contexts. I'm working on a JavaScript project, and would like the same ability to identify objects in the Chrome debugger (e.g. in the "Scope Variables" pane). Is this information tracked by the browser/debugger? Is there a different way to identify an object across contexts, without adding code (a purely IDE way of doing

Get request Initiator stack in Network tab

由 可紊 提交于 2019-12-08 16:41:53
问题 Each request in the "Network" tab of the dev tools has an "Initiator" column. For AJAX requests this is mostly useless since jQuery does all of the actual requesting and ends up in here. I vaguely read something in Google's documentation (https://developers.google.com/chrome-developer-tools/docs/protocol/tot/network) about how the Initiator object actually contains a stack trace ... So: how can I get that? 回答1: Late answer for this, but if you hover over the link for the Initiator the stack

Realtime css/less/scss edition using chrome DevTools in meteor

由 半世苍凉 提交于 2019-12-08 16:25:03
问题 I want to raise this question again. What was suggested in the answer to this question is to use old fashioned approach: Store css in public folder, and incude it via <link href= Add public folder to google chrome devtools workspace Not a rocket science at all. Works, but two things I don't like with this approach: It's still not native and for production I will have to move files from public folder Each time you edit css, meteor notices changes and reloads application.

问题 This question already has answers here : Inspecting WebSocket frames in an undetectable way (2 answers) Closed 4 years ago . I have spent a couple weeks on this issue and I can’t seem to find a resolution. Here is the use case. I am developing a chrome extension, one of the main purposes of this extension is to detect when a WebSocket opens or closes. I have looked at the HTML5 spec for WebSockets, they expose the following related methods/events: WebSocket.prototype.readyState = 0; WebSocket

Prevent manually set cookie from clearing in Chrome Devtools

由 拈花ヽ惹草 提交于 2019-12-08 07:52:47
问题 Chrome Version 73.0.3683.75 I noticed recently that whenever I manually set a cookie in Chrome and I either navigate away or refresh the page, then the value I assigned to the cookie is cleared and no longer persists. For some reason, adding a new cookie manually automatically assigns N/A to its Expires / Max Age property, which didn't happen before. The cookie value would at least persist during the browser session. I also see on the application panel that the row in which I add a cookie is

How to debug the next JavaScript event in Chrome, with scripts running in background?

由 不羁的心 提交于 2019-12-08 07:06:40
问题 In Chrome DevTools, I want to be able to hit F8 (pause script execution), and then interact with the page's elements to see what script it fires. The goal is to pause script execution as soon as I click on a button, for example. However, when hitting F8, I'm brought to a certain script file in the Sources tab. It seems to be constantly running, perhaps on a timer. I hit Shift+F11 to step out of the function, but this brings me to the "unpuased" state again in Chrome. In this case, the script
