问题 When I call this line: Object.getOwnPropertyDescriptor(HTMLElement.prototype,"innerHTML") For FireBug it returns : >>> Object.getOwnPropertyDescriptor(HTMLElement.prototype,"innerHTML") where for IE, Developer Tools it returns : >> Object.getOwnPropertyDescriptor(HTMLElement.prototype,"innerHTML") { get : function innerHTML() { [native code] } , set : function innerHTML() { [native code] } , enumerable : true, configurable : true } Do you know why it is different?

问题 My Chrome console returns Invalid CSS property name to a transform-origin CCS attribute as the site loads even though it works and I have a -webkit- prefixed version. The target CSS looks like this: -webkit-transform-origin: 0% 50%; -moz-transform-origin: 0% 50%; transform-origin: 0% 50%; Is it really an issue? 回答1: I've found the origin of my issue. The problem is that -webkit- browsers don't accept the transform-origin attribute when it is isolated from a supporting attribute (an attribute

问题 Is it possible to hide all console output from some scripts in Chrome's developer tools? Sometimes third-party libraries or APIs provide some information in console. That's OK, but can be very annoying when you want to debug your own code. More simply, can I ask developer tools to hide console output from https://www.google-analytics.com/analytics.js (just dummy example). Or even better, to show only error level for this source? Yes, there are some ways. I can add a string marker to text

问题 I created a new App at http://developers.facebook.com and I am trying to add friends as "Developers", but I get the following Error Message: param must be non-empty. 回答1: Normally, you could only add a developer if they are your friend. However, if the account is a business account, you cannot add people as your friends to the account causing you to not be able to add them as developers to your app. The only reason for this is because it auto-populates names when you start typing into the box

问题 I was modifying a theme for a WordPress based site, the Anew theme to be specific. Although I changed the theme options - style.css file and custom.css file, I couldn't change the color of the links. Then I used Chrome's Developer Tools to check where my rules were overridden. The overriding rule was on an (index) file, with parenthesis. With no relevant information on the internet, I decided to take a look at it later. After some hours, all my changes were committed and now it shows the new

问题 I'm looking for a fast way to download all of the images that i can see in the network tab on developer tools? they come through as data:image/png;base64 links. You can open them into a new tab individually and save them manually from there but that seems to be the only way. Saving the whole webpage or a .har file dosent seem to capture them. Neither dose any addon i have tried. :/ is there a fast way to save them all? since manually doing this would take a lifetime. Best regards, Matt 回答1:

问题 When I view my extension with the developer tools, I only see the generated background file, background.js; my content script doesn't appear under the content scripts tab. Any ideas why? The relevant part of the manifest looks like this: "content_scripts": [{ "run_at": "document_end", "js": ["postMsg.js"], "matches": ["https://groups.google.com/forum/*"] }], postMsg.js gets injected into the page, but never appears in the developer tool window, so I'm unable to debug it. 回答1: As long as you
