问题 How can I test that a web app successfully falls back from one faulty back-end API to a secondary legacy API service? Could Firebug or Chrome, or Fiddler do it? How can I setup my client to return error responses for ajax calls to a certain URL pattern? Using HTTPS. I don't have control over the server-side. I want to err just certain ajax calls the remaining should work the same (pulling the network plug is not an option). 回答1: Yes, Fiddler can do this easily. In Fiddler, click the

问题 Firebug doesn't show me the Cookies panel anymore. Somebody knows why? 回答1: You got automatically switched to the Firefox DevTools (with Firebug theme), because Firebug is discontinued and doesn't work anymore in multi-process Firefox. See the related Mozilla Hacks blog post for more info. The equivalent to the Cookies panel in Firebug is the Storage Inspector, which not only allows you to inspect cookies but also the local and session storage, the cache and IndexedDB entries. This tool needs

问题 I know this has been discussed in this topic: In Firebug 1.6.0, how do you tell what url triggered a 404 error?, but I'm thinking my situation is a little bit different. When I look at the net tab it shows the GET is referring to the 404 Not Found page. Here's a screenshot: http://www.fsclive.com/images/FirebugGrab.jpg The odd thing is if you go to this page, it works just fine and there is no issue accessing this page. I'm wondering if it's pointing to the 404 Not Found page only after it

问题 FireBug always shows warning messages from jQuery eg reference to undefined property o.cache[H][E] (function(){var l=this,g,y=l.jQuery,p=...ch(function(){o.dequeue(this,E)})}}); jquery.min.js (string 12) Can I set up FireBug not to show certain warnings for certain scripts? 回答1: I guess that warning will go away if you use: Firebug > Console Panel > Mini-menu on tab > Strict Warnings OFF 回答2: I doubt this is an issue with either jQuery or Firebug. Debug your code and find out what's leading

问题 I'm wondering what's the best way to combine multiple .html files (spread across many folders) into one single html file. If someone could create a simple bash command that would be fantastic. (This is a workaround so I can use firebug's command line API to effectively search an entire site for html selector combinations. As far as I know, firebug can only search on one page.) Any help is greatly appreciated for this stymied front-end designer. 回答1: cat file1.html file2.html file3.html >

问题 I am working on a site, when I look at it with firebug in firefox various elements seem to have heights like 133.8 pixels, whereas firebug lite in chrome reports the height as 133px for the same method. Is this a difference in the browser rendering, or is it just a curiousity brought on by firebug? I thought pixels had to be measured in integers... 回答1: You can have decimal values in units other than px . Like em, in, etc. 回答2: Funny thing. I just tried today and booth Chrome 25 and Firefox

问题 I'm optimizing the loading times in a web app and I don't know what's the problem. Firebug's Net panel is showing time holes between requests. Can someone explain me this chart? 回答1: The gap between the requests can have two reasons: Time needed to parse the requested page When you request a URL, the browser needs to parse the returned contents to check whether they contain URLs to other ressources like JavaScripts, CSS files, images, etc. Subsequently requested ressources need to be parsed,

问题 I have to use an external js file in order to load jquery. The code from my js file is below: document.write('<script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script>'); (function($) { $(document).ready(function() { alert('it works!!'); }); })(jQuery); In the firefox firebug console I see this error: "jQuery is not defined" and I think it is because the jQuery library is loaded after the $ function from my js file. Do you have any idea

问题 I want to use some IDE which allows me to change the javaScript code on the fly and run it in browser. I don't think I can do this in Firebug. Which IDE/software should I use for JavaScript development? 回答1: Yes you can do this in firebug console. Click on console and you can start typing. You can click on the bottom right red icon to expand the typing area. 回答2: The Sublime Web Inspector looks like it could do what your after. It supports: Breakpoints Console Interactivity Debugger

问题 I am trying to use sessionStorage on a page but it is giving me an error. Here is the code: <script type="text/JavaScript"> sessionStorage.setItem("classname", "value1"); sessionStorage.setItem("classdesc", "value2"); </script> The error I get from firebug console is: Operation is not supported" code: "9 When I try to use localStorage it works fine, so why does sessionStorage cause an error? 回答1: The only thing I can think of is that "the page isn't ready", try placing this code at the end of
