Firebug: How to inspect elements changing with mouse movements?

由 不羁岁月 提交于 2019-11-26 19:05:10
问题 Sometimes I need to inspect elements that are only showing up on a page if you put mouse over some area. The problem is that if you start moving mouse towards firebug console in order to see the changes, mouse-out event is triggered and all changes I am trying to inspect disappear. How to deal with such cases? Basically I am looking for something that would either: Switch to firebug console without moving a mouse (using keyboard shortcuts maybe? But I can't figure out how to use firebug with

How to debug the http response headers from a HTTP call

由 佐手、 提交于 2019-11-26 16:59:48
问题 I've installed FireBug, but I am not sure how to find out if a certain http header is present in my HTTP response. Where should I look for this information? 回答1: Use the Net tab in Firebug to monitor network traffic. There you can see the complete headers as well as the timing and content of any network/HTTP queries. Looks like this: 回答2: Fiddler is the best tool I know of to do this and much more, including inspecting the entire request/response in many formats including a nice XML browser.

How to revert Firebug to old version?

由 自作多情 提交于 2019-11-26 16:50:21
问题 I've opened a Firefox today, hit the Firebug button and it showed me that in the new version it is integrated into the developer tools. I hit ok and realized that it doesn't work at all (everytime using Inspect Element the <body> element is selected). So I would like to revert that setup back, but I cannot find where to switch it. I tried to reinstall Firebug, but that setup is stored somewhere so it automatically starts the DevTools instead of Firebug. Any help how to revert back to the

Firebug toolbar button is always shown deactivated since Firefox 51.0.1

问题 Recently my Firefox got updated to version 51.0.1. Initially it was showing some reminder check (I'm not clear with that) related to Firebug, but I ignored it. Now, the Firebug toolbar button is always shown deactivated. I've reinstalled Firebug several times, but the result is always the same. Is there any compatibility issue? How do I activate Firebug? 回答1: There is a solution to use firebug [version 2.0.18] in latest version of firefox [this time 51.0.1] To enable old Firebug In address

Why does Firebug show a “206 Partial Content” response on a video loading request?

由 删除回忆录丶 提交于 2019-11-26 16:25:49
问题 I have a bunch of html5 video elements, with their preload attribute set to "auto". They start loading just fine, but I think there might be a problem with their caching, because each time I reload the page (without clearing the cache), they start all over again. When I checked the Network panel in firebug, I noticed everything else (images and files) was giving me a "304 not modified" message as espected, while the videos (and audio) files were giving me a "206 partial content" message, in

How do I dump JavaScript vars in IE8?

由 て烟熏妆下的殇ゞ 提交于 2019-11-26 15:19:10
问题 I have an object I need to examine in IE8. I tried the developer tools and console.log , their Firebug equivalent. However, when I output the object to the log: console.log("Element: ", element); console.log(element); I only get the string LOG: Element: [object Object] instead of a clickable, examinable dump. Is it possible to dump an object to the Log and examine its members, like in Firebug? I can't use a homemade dump() function because the element I want to examine is so huge the browser

Finding memory leaks in JavaScript using firebug?

由 ⅰ亾dé卋堺 提交于 2019-11-26 14:15:52
问题 Are there any add-ons for Firefox that I can use to find out with part of the JavaScript causes memory leaks? 回答1: I've got nothing for firefox, but the webkit inspector in Chrome has a profiler built in that is great for that kind of thing. As an added bonus it also shows you all browser events such as repaints, so you can engineer your code to have the least impact on the browser. 回答2: Use Drip.exe / IEleak, I used it a lot to search for memory leaks! Other hits: jQuery itself prevents a

Differences between socket.io and websockets

由 与世无争的帅哥 提交于 2019-11-26 13:52:35
What are the differences between socket.io and websockets in node.js? Are they both server push technologies? The only differences I felt was, socket.io allowed me to send/emit messages by specifying an event name. In the case of socket.io a message from server will reach on all clients, but for the same in websockets I was forced to keep an array of all connections and loop through it to send messages to all clients. Also, I wonder why web inspectors (like Chrome/firebug/fiddler) are unable to catch these messages (from socket.io/websocket) from server? Please clarify this. Timothy Strimple

setting innerHTML with a script inside

由 耗尽温柔 提交于 2019-11-26 12:31:39
问题 If I run the following line in Firebug on any page: document.documentElement.innerHTML=\"<script>alert(1)</script>\"; why isn\'t the alert command executed? 回答1: It looks like that your <script> tag is being added as you expect, but the code within it is not being executed. The same failure happens if you try using document.head (or any other DOM element, it seems). For whatever reason (possibly standards compliance, possible security), inline code inside of <script> blocks that are added via
