问题 Is there a way to determine a line and filename from which XHR was issued in Firebug or Web Inspector (maybe Opera Dragonfly/IE Developers Toolbar)? If there isn't, what is the best way to find that out? Just searching the codebase for the URI called?

Script Tab XHR Breakpoints(on right hand side) Click the + and press return A new item will be added saying "Any XHR"

Can Firebug or any tool inspect the element and actually tell which font is being used? (instead of a list)

阅读更多关于 Can Firebug or any tool inspect the element and actually tell which font is being used? (instead of a list)

问题 Usually on Firebug, when inspecting an element, I get a list of fonts, and will actually need to go to the system's Fonts folder and check the names one by one to see if that's the one being used. Is there a way to show the font being used directly using Firebug? Or if Firebug doesn't have this feature, can any other add-on do that? 回答1: You can edit the list of fonts on the font declaration in firebug. Starting from the first font, I stick an 'x' in the name. If the font on the page changes,

How to access line numbers when wrapping Firebug (or similar) Console api

阅读更多关于 How to access line numbers when wrapping Firebug (or similar) Console api

问题 I have wrapped the console API to provide granular logging levels as well as few other sugar features. This works fine, the only problem is that firebug (or whatever other console) will always report the line number the log came from as the line the console API itself is invoked. How would you suggest I make the console log the line number at which I call my wrapper function? I would prefer a cross browser solution but failing that a firebug plugin could be a good start. fyi I call my loging

文件上传漏洞的原理、危害及防御

阅读更多关于文件上传漏洞的原理、危害及防御

一. 什么是文件上传漏洞 Web应用程序通常会有文件上传的功能, 例如在 BBS 发布图片 , 在个人网站发布ZIP 压缩包, 在办公平台发布DOC 文件等 , 只要 Web应用程序允许上传文件, 就有可能存在文件上传漏洞. 什么样的网站会有文件上传漏洞? 大部分文件上传漏洞的产生是因为Web应用程序没有对上传文件的格式进行严格过滤 , 还有一部分是攻击者通过 Web服务器的解析漏洞来突破Web应用程序的防护, 后面我们会讲到一些常见的解析漏洞 , 最后还有一些不常见的其他漏洞, 如 IIS PUT 漏洞等 . 二. 文件上传漏洞的危害上传漏洞与SQL 注入或 XSS 相比 , 其风险更大 , 如果 Web应用程序存在上传漏洞 , 攻击者甚至可以直接上传一个 webshell到服务器上 . 三. 常见的解析漏洞 1.IIS 解析漏洞 IIS6.0 在解析文件时存在以下两个解析漏洞 . ①当建立 *.asa 、*.asp 格式的文件夹时 , 其目录下的任意文件豆浆被 IIS 当作 asp 文件来解析 . ② 在 IIS6.0 下 , 分号后面的扩展名不会被解析 , 也就是说当文件为 *.asp;.jpg 时,IIS6.0 同样会以 ASP脚本来执行 . 2.Apache 解析漏洞在 Apache 1.x 和 Apache 2.x

“this” keyword in jQuery.map()

阅读更多关于 “this” keyword in jQuery.map()

问题 I want to know the differences between: $('a').map(function(){return this}) $.map($('a'), function(){return this}) They behave differently when I test them in firebug console. 回答1: Having just briefly tested, they do perform differently. 'this' in the context of the latter references the window object. However you do have access the current element when looping through the object/array passed in: $('a').map(function(){ return this }); $.map($('a'), function(el){ return el; }); The latter is

Facebook和新的Twitter URL中的shebang / hashbang（＃！）是什么？

阅读更多关于 Facebook和新的Twitter URL中的shebang / hashbang（＃！）是什么？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我刚刚注意到，我们现在习惯的长而复杂的Facebook URL看起来像这样： http://www.facebook.com/example.profile#!/pages/Another-Page/123456789012345 据我所知，今年早些时候，它只是一个类似于URL片段的普通字符串（以 # 开头），没有感叹号。但是现在是shebang或hashbang（ #! ），我以前只在shell脚本和Perl脚本中看到过。新的Twitter URL现在也带有 #! 符号。例如，Twitter个人资料URL现在如下所示： http://twitter.com/#!/BoltClock 做 #! 现在在URL中扮演某些特殊角色，例如对于某个Ajax框架或某些东西，因为新的Facebook和Twitter界面现在基本上已被Ajax化？在URL中使用它会以任何方式使我的Web应用程序受益吗？ #1楼为了对所有这些问题进行良好的跟进，Twitter是hashbang URL和单页面界面的先驱者之一，他承认hashbang系统从长远来看很慢，实际上他们已经开始撤消决策并返回到老派的链接。有关此的文章在这里。 #2楼现在不推荐使用此技术。这曾经告诉Google如何索引页面。 https:/

Is this correct? Should firebug see SSL-protected AJAX?

阅读更多关于 Is this correct? Should firebug see SSL-protected AJAX?

问题 I have enabled SSL and I am doing a jQuery AJAX post request and sending some fields to the server. When I look at the AJAX post request through firebug under the post parameters I see all the fields in clear text. So this means I can see the passwords in clear text. Is this normal? I am also looking at it with fiddler and it does not even log this AJAX request(so its like the request was never made). So is it just because firebug is installed in the browser and can capture it or what? 回答1:

gzip working but YSlow indicates it's not

阅读更多关于 gzip working but YSlow indicates it's not

问题 I'm getting used to Firebug and YSlow in particular. One of the things I'm looking at is the gzip compression. YSlow still gives my site an "F" and indicates that my CSS and JavaScript files are not being compressed. However, if I run an external gzip test against my site (such as http://www.gidnetwork.com/tools/gzip-test.php ) it tells me that gzip is working and gives me my savings, although I think this may just be the HTML. This is the relevant section of my .htaccess file: <IfModule mod
