Firebug debugging parsing error?

由 旧巷老猫 提交于 2019-12-10 11:05:04
问题 I am getting some wierdness with the Firebug debugger. I have screenshots that explain the problem: http://www.tqis.com/pen/eloquency/images/tmp/before.png As this screenshot demonstrates, the line numbers after 885 are not colored green, which means Firebug does not recognize these statements as executable code. After a confounding hour or so, I got these results http://www.tqis.com/pen/eloquency/images/tmp/after.png The only difference between the files in the editor is the commented blank

四种常见请求头设置

由 限于喜欢 提交于 2019-12-10 08:39:21
在post请求中，根据请求设置的不同，有以下几种设置，介绍如下： application/x-www-form-urlencoded multipart/form-data application/json text/xml application/x-www-form-urlencoded 这应该是最常见的POST提交数据的方式了。浏览器的原生form表单，如果不设置enctype属性，那么最终会以application/x-www-form-urlencoded方式提交数据。请求类似于下面这样（无关的请求头在本文中都省略掉了）： POST http://www.example.com HTTP/1.1 Content-Type: application/x-www-form-urlencoded;charset=utf-8 title=test&sub%5B%5D=1&sub%5B%5D=2&sub%5B%5D=3 首先，Content-Type被指定为application/x-www-form-urlencoded；其次，提交的数据按照key1=val1&key2=val2的方式进行编码，key和val都进行了URL转码。大部分服务端语言都对这种方式有很好的支持。 很多时候，我们用Ajax提交数据时，也是使用这种方式。例如JQuery和QWrap的Ajax，Content

问题 How to debug Greasemonkey scripts in Firebug? I can't debug any Greasemonkey scripts in Firebug because they don't appear in the list under the Script tab (anymore).

Way to get Chrome to always re-download styles and images on every visit to the page during development/testing?

由 ℡╲_俬逩灬. 提交于 2019-12-10 03:29:14
问题 As brilliant as Firebug is, I would consider switching my JavaScript debugging to Chrome if I could figure out how to get it to always re-download styles and images on every visit to the page? When I'm testing a page in Firefox, it always gets the latest version. But in Chrome I often end up scratching my head over something that turns out to be a simple issue of the browser caching some earlier styles or images. Is there a way to configure Chrome to cache less while you're developing? 回答1: I

Fiddler vs Firefox w/ Firebug

由 吃可爱长大的小学妹 提交于 2019-12-10 02:30:14
问题 Fiddler does look interesting and I've seen people recommending it as a good debugging tool but a quick runthrough I don't see anything all that great that we dont already have in Firebug. What can Fiddler do that Firebug cannot? Conversly what can Firebug do that Fiddler cannot? 回答1: Yes it can - it is capable of showing HTTP messages from any program, not only web browsers. 回答2: Fiddler is an extensible web-debugging platform which can be extended with any .NET language. It allows you to

Firebug 2.0 with FF 30 can't set breakpoints

由 ∥☆過路亽．° 提交于 2019-12-10 01:54:33
问题 When I set a breakpoint with Firebug 2.0 in Firefox 30, I can't seem to set breakpoints using the line numbers column. It just throws up a spinner instead of the red circle. Is there some new configuration option or something else that I am missing? Do I have to execute my code for the breakpoint to take effect? 回答1: This sounds like a bug in Firebug 2.0, which you should report in the Firebug issue tracker, so the team behind Firebug can fix it. Before you do this you should follow the steps

Can I copy the list of HTTP requests made by a web page out of Firebug’s Net panel?

由 旧城冷巷雨未停 提交于 2019-12-10 01:52:56
问题 In the Firebug Net panel, you can get a list of all HTTP requests made for the current page. http://getfirebug.com/wiki/index.php/Net_Panel Is there a way copy this list as text, so that I can paste it somewhere else for my own records? I’m doing some optimisation work, and it’d be really handy to save the requests made for pages before I optimise, so that I can check what effect my optimisation has. Alternatively, are there any other tools that would give me the same file information (i.e.

Is it possible to stop a javascript with Firebug without using breakpoints?

由 别等时光非礼了梦想. 提交于 2019-12-10 00:50:28
问题 Is it possible with Firebug to stop a javascript with a press of a button or a keyboard shortcut instead of stopping it by setting a breakpoint? Why would I like to do this? We have a very dynamic website with lots of animations. It would be a great help if I could just stop the scripts at the moment the animation is doing something I want to inspect. That would be a lot faster than fiddling with the breakpoints. 回答1: This is how I did it, from the web console (not the scratchpad), run:
