Show FPS meter Chrome 33

北战南征 提交于 2019-11-28 02:29:55
问题 I think I'm going mad. I use the FPS meter in Chrome all the time, but I can no longer find it. If I go into settings in the dev tools it is not there. Can anyone guide me as to what I am doing wrong? I am using a Windows PC and Chrome 33.0.1750.117 回答1: Go to about:flags and enable the the FPS counter there. You might also need to enable GPU composition on all pages. I can't enable this on my current machine, so I'm afraid I can't test it myself. See this article for more information 回答2:

element.style in chrome element inspector?

好久不见. 提交于 2019-11-28 02:24:23
问题 When I inspect elements in Chrome, under my styles I have element.style {} , What does this refer to? It contains styles I am not including in my code source. 回答1: Those are inline styles.

Highlight node with chrome devtools extension [closed]

一笑奈何 提交于 2019-11-28 00:53:24
问题 I would like to highlight a dom element from my chrome dev-tools extension in the same way as Element inspector (in dev tools) does. Is there some special API for this? Thanks 回答1: Whenever you evaluate some code in the inspected page using DevTools console, DevTools expose a bunch of helper calls known as command line API. This API includes inspect() call that has the same effect as if user invoked "Inspect Element" from the context menu, i.e. brings up the Elements panel and highlights the

is there a way to save css/js changes of remote resource between page reloads or map remote resource to local in devtools?

瘦欲@ 提交于 2019-11-27 23:31:34
I know about Workspaces recently introduced in DevTools but that is not that i need. For example: page uses jquery that is loaded from CDN, i modify jquery library code, press ctrl-s, reload page -> modifications are lost. Or i want to debug some site i don't have an ability to change files of. I don't want only save changes as in save CSS - while browsing, how can I save the css files from inside chrome dev or firebug to local directory , i want them to persist between page reloads. You got most of it, but here's the slight change: Make a change in the Styles pane (or in Sources), then click

Auto-scrolling Chrome's DevTools console

痞子三分冷 提交于 2019-11-27 21:06:39
问题 Since its inception few years back, Chrome has become a de-facto IDE for web development. I've been using it's Canary(Version 28.0.1464.0) channel for quite a bit and been happy as a clam. Only issue that keeps bothering me is the lack of ability to have the DevTools console pane, auto scroll to the last message added. I understand that many folks would prefer to have the current behavior. However I was wondering: Does anyone knows how (if even possible with the current release) to flip the

Debugging Chrome extension with access to chrome.devtools api

别说谁变了你拦得住时间么 提交于 2019-11-27 20:11:01
I am beginner in Chrome extensions development. I need to extend existing extension ( angularjs-batarang ), but I have some problems with debugging. manifest.json has entries: "background": { "page": "background.html" }, "devtools_page": "devtoolsBackground.html" The question is: how to debug devtools_page ? I added to manifest.json additional entry "options_page": "devtoolsBackground.html" and when I add this extension to Chrome I have possibility to run options page from chrome://extensions . It works because application stops at breakpoints. But unfortunatelly I have no access to chrome

customize chrome developer tool javascript debugger keyboard shortcuts?

久未见 提交于 2019-11-27 19:35:45
I can't believe that neither a Google or SO search has turned up a definitive answer or even much discussion for this, but: Is it possible to edit/customize keyboard shortcuts in the Google Chrome JavaScript debugger? if so, how? I'm used to Eclipse's F5 / F6 / F7 / F8 debugger step into/over/out of/resume keys, and want the same bindings in Google Chrome. F10 / F11 are default Expose keys for OSX and therefore not ideal for debugger control. I'm open to unorthodox solutions, e.g. Quicksilver/AppleScript.
