firebug

问题 Firebug looks not capable to check js syntax error... Is there any good way to do that? Currently I just wrote a js but the firebug didn't show any error but the functionality is totally broken. 回答1: Firebug does do it. Make sure that you have JavaScript Console enabled, you can do so by clicking the Console dropdown and from their select Enabled . You need to press F12 key to open firebug and once you refresh the page, you will see any errors you have in your script in the firebug js console

问题 If a disabled drop-down list is dynamically rendered to the page, it is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute. This code: protected override void OnLoad(EventArgs e) { var ddlTest = new DropDownList() {ID="ddlTest", Enabled = false}; ddlTest.Items.AddRange(new [] { new ListItem("Please select", ""), new ListItem("test 1", "1"), new ListItem("test 2", "2") }); Controls.Add(ddlTest); } results in this HTML

问题 Using ColorZilla I found an interesting feature. If I pick a color from firefox (bars,tabs or anything else of the browser) and then go to: ColorZilla > Inspect Last Element > In Firebug Then I can see the markup,css,js that firefox uses in the firebug panel just like a website. Is there any solution to view this code without use Colorzilla? 回答1: It sounds like you're after Chromebug. Chromebug is the Firebug code adapted for XUL applications. It is the debugger that Firebug developers use to

问题 I'm working on a project, and my task is to get an external html table identified by #s_table_0 using the php function file_get_contents($url) . and then manually get CSS and JS related with that Tag. I just can't find any trick in 'google chrome developer tools' to do the magic for me, instead of get all the css file and delete what have no relation with that table, and then hardly try to find the related JS. So,i would like to know if there is any tool or some trick to get only CSS and

问题 Most jQuery code uses anonymous functions, such as: jQuery('someelements').someEvent(function() { // code here }); This works well, but doesn't do so well for debugging. I tried to find the source of some anonymous functions using both Firefox Firebug and Chrome's inspector, with the pause javascript functionality, but the actual code it calls is in the jQuery js file, and stepping through the code never tells what line, or even what .js file added that event. How can I see where the action

问题 Like firefox has firebug as a efficient tool for web application developer, I am wondering is there any similar tool in opera which is for web developers? 回答1: In Opera you can use DragonFly Opera Dragonfly 1.0 is included by default with the Opera browser. Launch Opera Dragonfly with Ctrl + Shift + I on Windows and Linux, or ⌘ + ⌥ + I on Mac. Alternatively, target a specific element by right clicking in the page and selecting "Inspect Element". http://www.opera.com/dragonfly/ A video on

问题 So in my website, I use jquery to fetch data through ajax. AS part of the ajax response, some of the javascript code comes as well which is executed. The problem is how to debug this javascript in firebug or other tools. This is my experience so far: putting debugger; doesn't work For some javascript, can't set the breakpoint as that script is not yet loaded. even if this new javascript calls some other function thats already loaded (i.e. i can see it in firebug and set a breakpoint), that

问题 Using firebug for Firefox, I can set a breakpoint in my JS code, refresh the page and the code will automatically pause at my breakpoint (my code runs on page load). When I do the same in Chrome Developer Tools (Ctrl + Shift + J), it does not stop at the breakpoints. How do I get the code to stop at the breakpoints? Also, my console.logs appear in firebug for Firefox, but not in the Chrome console. How do I get the Chrome console to display my console logs? 回答1: Breakpoints work for me; Press

问题 console.log(a()); function a(){ console.log("hello"); } From above code, i will expect "hello" (and some undefined s) to be logged on console. But firebug gives ReferenceError: a is not defined So firebug does not do hoisting? 回答1: The reason for the issue is that functions do not hoist when declared inside a child block. by MDN (Much covered here is not standard ECMAScript). Compare the following snippets: alert(c()); function c(){return 42;} and { alert(c()); function c(){return 42;} } The

问题 I want to try some different options with some javascript (jQuery) to see which is the fastest, however I can't get profiling working properly. Here is the code I want to test. $this.keypress(function(e) { console.profile("test"); //retrieve the charcode if possible, otherwise get the keycode k = e.which ? e.which : e.CharCode; if (blockKeyCodes.indexOf("|" + k + "|") != -1 || e.ctrlKey && k == 86) e.preventDefault(); console.profileEnd(); }); However, when I run this the console states "no
