【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我需要调试一个使用jQuery进行一些相当复杂和混乱的 DOM 操作的Web应用程序。 某一时刻，某些与特定元素绑定的事件并未触发，只是停止工作。 如果我有能力编辑应用程序源代码，那么我将向下钻取并添加一堆 Firebug console.log() 语句和注释/取消注释代码段以尝试找出问题所在。 但是，假设我无法编辑应用程序代码，并且需要使用Firebug或类似工具完全在Firefox中工作。 Firebug非常擅长让我浏览和操作DOM。 不过，到目前为止，我还无法弄清楚如何使用Firebug进行事件调试。 具体来说，我只想查看在给定时间绑定到特定元素的事件处理程序的列表（使用Firebug JavaScript断点来跟踪更改）。 但是Firebug无法查看绑定事件，或者我太笨了，找不到它。 :-) 有什么建议或想法吗？ 理想情况下，我只想查看和编辑绑定到元素的事件，就像今天编辑DOM一样。 #1楼 我还在Chrome存储区中找到了 jQuery Debugger 。 您可以单击一个dom项目，它将显示绑定到它的所有事件以及回调函数。 我正在调试无法正确删除事件的应用程序，这帮助我在几分钟内找到了问题。 显然，这是针对Chrome的，不是针对Firefox的。 #2楼 在jQuery 1.7+中使用 $.

Result of 4.08-1.36 in console [duplicate]

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Is JavaScript’s Math broken? I noticed a weird behavior when I try to run 4.08-1.36 in the Chrome console or Firebug. The console returns 2.7199999999999998 as a result when the result should be 2.72. I was wondering how is this possible. Any ideas? 回答1: Computers store numbers in binary instead of decimal. Just as you cannot represent the fraction 1/3 exactly in decimal form, you cannot represent the fraction 1

How to use Firefox Firebug on Sub-Menus

问题 How to use Firefox Firebug on Superfish v1.4.8 Vertical Menu sample but on the sub-menus not the top menu. Superfish Menu I basically want to be able to freeze Firebug on a sub-menu selection to process but unsure how to. Thanks. 回答1: You can set a breakpoint within the menu's javascript handling code to abort processing before any of the mouse-out or "hide the menu" type code is executed, which would leave the menu in the open state for you to inspect. You do that via the 'Script' tab in

How can i hide my json requests from showing in firebug

问题 how can i hide my json request URL from firebug console? It appears full as anyone can take it and retrieve our data to their website note i am talking to a third party and i can't do restricted calling domains on it 回答1: In principle, you can't, and you must design your system so that you don't need to. You can try to obfuscate the request itself, but only if you control the protocol (which it sounds like you may not). But even then you're going to send all the javascript required to

问题 I have set up a custom firefox profile and load it when selenium RC starts. The profile has firebug installed, and when I manually launch firefox with that profile, firebug is active. However, when selenium launches that profile, firebug is in the lower right, but it is not enabled. How can I ensure it is enabled at launch? OR, how can I enable it (javascript or ?) - I am using the Java API. 回答1: The way to do that is to open Firefox using your custom profile. Right-click on the Firebug icon

问题 This is an extension of a question I have posted here. I'm having trouble manipulating js Objects, and I think it has something to do with scope or how the Objects are populated. I'm trying to use Firebug to get to the bottom of the issue, and did find one discrepancy that I can't explain. Does anyone know why sometimes Console will show an object like this : Where it shows the contents of the Object And sometimes like this: Where it looks as if the Object is empty However, the object isn't

问题 is there any way to start automatically the Inspector after starting Chrome? is there any way to start automatically the Firebug after starting Firefox? Regards Javi 回答1: In Firefox you can set Firebug to be always on by opening about:config and setting extensions.firebug.allPagesActivation to on . Note that this will have Firebug always active and recording -- which you can see by the Firebug icon being colored -- but the panel may be minimized. Show it by clicking the icon or using the
