问题 I want to clear the console suggestion because I entered some data in it and dont want it to been seen by others. Just want to know if there is way or do I just go to %appdata% and clear off things. 回答1: [EDIT] As of Chrome 50, you can use "Clear console history" from the console context menu. The situation seems to be a bit unlikely to happen (confident information in the devtools console?), but I've found the problem of clearing command history interesting. Especially, when it turned out

What is the Chrome Dev Tools “Hit Test” timeline entry?

问题 When looking at a Chrome Dev Tools timeline I noticed that there was a "Hit Test" entry every time somethings happens: Does anyone know what it is? I've done my googling, but am still at a loss. Thanks! 回答1: A hit test is how a contact (mouse/touch) event is checked to see what it "hit" in the DOM. https://www.chromium.org/developers/design-documents/compositor-hit-testing describes some of this. 来源： https://stackoverflow.com/questions/33174286/what-is-the-chrome-dev-tools-hit-test-timeline

How can I measure pixels in Chrome without an extension?

由 99封情书 提交于 2019-12-09 08:01:07
问题 Due to security limitations at work, I am not allowed to install Chrome extensions. Chrome has a ruler built in to the developer tools, but I can't figure out how to define start and end points like a ruler would permit. Are there any tools or techniques for measuring pixels that don't require installing a Chrome extension? 回答1: You could create your own ruler functionality and paste it into the console. Here's a basic example: var fromX, fromY; var svg = document.createElementNS ('http://www

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

由 可紊 提交于 2019-12-09 06:53:24
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 running in the background is Plupload jQuery plugin. Can I deactive or ignore those scripts running

chrome.browserAction.setIcon not doing anything

由 ￡可爱￡侵袭症＋ 提交于 2019-12-08 21:53:00
问题 I am making a chrome extension, and the extension has two modes: always on ( alwaysOn ), or only when the user clicks it ( onClick ). I want to change the icon to be blue or red depending on the user's mode, so they can see it at a glance. However, after adding the chrome.browserAction.setIcon() line, the icon still doesn't change when it needs to. It just stays on the default logo. Here is my background.js: // Get the behavior of the plugin; the default is set to "onClick", the other option
