firebug

问题 I noticed that the source code shown in Firefox appears to be incomplete. I have the latest version. When using the Firebug plugin to look at a webpage, I am able to find elements which are simply not recognized by Firefox. This is for a automated script I am working on. I am wondering several things: Why is a firefox plugin able to recognize elements Firefox is not? Is there a way to pass the source from Firebug engine to Firefox, or any other viable workaround which would enable Firefox to

问题 I'm wondering how the sequence shown below could possibly occur. Here is the function in question: WebSocketConnector.prototype.sendMessage = function(message) { if (socket !== null) { socket.send(message); console.log('Sent: ' + message); } else { alert('Failed to send message. WebSocket connection not established.'); } }; And here is what happens when I debug a call to this function: 1. Start at line 32. 2. Step In, advances to line 33. 3. Step In again, advances to line 34. 4. Step in one

问题 I am using firebug to profile our webapp. I am trying to make changes to speed it up. I want to make sure that each change that I make increases the efficiency of the app. What I would like to do is save or print the Net tab and the Javascript profile of the site I am viewing. How can I do this? (I would just take a screenshot but the output spans several pages so taking a screenshot is not practical) 回答1: Here you go: http://www.softwareishard.com/blog/consoleexport/ 回答2: Jan Odvarko at

问题 Does Firebug have something built-in to disable all javascript for a site/page? 回答1: Not that I know of. But you can use the web developer toolbar or noscript addons to do that. 回答2: In firefox 4 you can just disable javascript in the content tab of the options dialog. Just uncheck "Enable Javascript". 回答3: I would look at noscript. Also the firebug folks (john barton I think is the guy's name) are very responsive so if you want a feature post it on the google group or bug/enhancement tracker

问题 I am behind a proxy at work (using NTLM authentication). Whenever I load up a page, my Firebug console gets flooded with messages like this: "NetworkError: 407 Proxy Authentication Required - http://somewebsite/Scripts/jquery-1.8.2.min.js" It does that for all URLs referenced on that page: JS, CSS, Image, whatnot. The annoying thing is that the file is actually successfully loaded. It seems that Firefox hits the 407 Error, spams the log and then loads it anyway with the NTLM credentials. Is

问题 Firebug shows some requests in Gray(screenshot attached and marked in Red) with status code 200 and some requests shows black with status code 200. What is the difference between two requests? 回答1: The gray requests are the ones loaded from the cache, as described in a feature-promo here: http://getfirebug.com/network Cached or not cached Not all network requests are equal - some of them are loaded from the browser cache instead of the network. Firebug provides status codes for every request

问题 I think i might be going mad. I use console.log() to see the state of an object and then on the next line do a console.log() on a particular property of the same object and get different values for each. The code i'm using is: console.log(this.pictures.Items[pic].val); for(var i in this.pictures.Items[pic].val) { console.log("property: %s, value: %s", i, this.pictures.Items[pic].val[i] ); } and firebug outputs: Picture { isLoaded=true, isSelected=false, img_src="imgs/image1.jpg", more...}

问题 I am struggling with a reluctant a:hover css style which I cannot override. I tried to inspect the element in Firebug, but I cannot see why it won't work. I don't even see how to properly inspect a:hover css event in Firebug. I have seen: Hover Inspection in Firebug http://blog.borngeek.com/2010/04/16/hover-inspection-in-firebug/ but I have not figured out how to reproduce the steps mentioned there. Also: Pseudo-Phantoms http://meyerweb.com/eric/thoughts/2009/11/03/pseudo-phantoms/ How do I

问题 So we have reached that stage in a web dev project where we need to see how things look in IE. Sigh. So the fabulous Firebug is not available for IE. But a lite version is - as a bookmarklet, and is apparently compatible with IE6+. But how the how the hell do I add a bookmarklet to IE8? I am unable to drag and drop to the Favourites bar (is this the same as bookmarks?). I can't add it through the Favourites add option as it contains "illegal" characters. So how do I do this? All I want to do

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . What is the best way to develop a website for mobile devices? I can't seem to find a simulator/emulator for the mobile devices.
