How can I watch (i.e. debug) xmlHttpRequest() actions in IE8 ? (using Firebug Lite)

偶尔善良 提交于 2019-12-03 10:01:10
I normally do my web dev using Firefox - I periodically test for cross browser compatability of my pages by using FF and IE. I have just found that one of my AJAX pages stopped working in IE - although it works fine in FF. With FF, I always use FireBug to debug my Ajax interactions. I am looking for a similar tool to use with IE - to see what it is causing it to fail, even though it is a straightforward AJAX process on the page. I downloaded Firebug Lite and that was very helpful, as it brought a familiar dev environment into IE. Unfortunately, I have not been able to debug my AJAX

Telling Firebug to Break as Soon as any Javascript is Executed

人盡茶涼 提交于 2019-12-03 09:19:50
问题 I've inherited a pile of code that's doing unexpected things when I click on some <button> elements. The page has a lot of Javascript, and it's unclear what, if any, events have been setup on the button or its parent elements. I'm trying to find where execution starts so I can debug what's going on. Is there a way to have Firebug (or any Javascript debugger) break whenever any javascript code is executed? Maybe someway to setup a break point on each line programmatically? Or is there some

Does the “Set next statement” feature exist in Chrome's Dev Tools or in Firebug?

IE's development tools, more specifically its JavaScript debugger, offer a "Set next statement" command, which enables you to specify which statement should be executed next. That way, you can effectively skip certain parts of functions or even (again, effectively) return from a function early. So, for this function... function test () { alert(1); alert(2); alert(3); } If we set a break-point on the first alert, and then invoke the function, we can execute the first alert (F10), and then right-click on the third alert and choose "Set next statement". Now, if we press F10, the third alert will

What do the FireBug DOM colors mean?

丶灬走出姿态 提交于 2019-12-03 09:06:23
I'm confused with these colors. I noticed there are 4 colors showing in the left hand column of FireBug DOM tree: Bold black Black Bold green Green In the right hand column: Blue Red Bold green Green Multiple color elements representing object structures. What do this colors represent? And why, e.g, I can access window.document.URL and I can't access window.document.body in Console even though they are both in the "not-bold black" category in the DOM tree? Thanks a lot Fatih Here is the correct answer. Bold Black Objects Black DOM objects get in gray "Getter" functions Bold green User

How do I turn off the console logging in App Engine Channel API?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I've implemented the Channel API w/ persistence. When I make a channel and connect the socket (this is on the real app, not the local dev_appserver), Firebug goes nuts with log messages. I want to turn these off so I can see my OWN logs but cant find any documentation on how to disable the Channel API console logging. one thing I'm probably doing differently than most is that I'm connecting cross-domain... which the Channel API supports (note the first message in the stream... if you can view that pic) Does anyone know? UPDATE I finally

Can Firebug set breakpoints in external JavaScript files?

(I suspect I've found a bug in jQuery and I want to be able to step through jQuery as it's handling events to see what it's doing.) 回答1: Not sure if I understand the question, but I don't think Firebug treats external javascript any differently than internal one. Just go to the "script" tab, select the .js file in the drop down list and set your breakpoint. 转载请标明出处: Can Firebug set breakpoints in external

Firebug 2.0 with FF 30 can't set breakpoints

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 described on the first aid page for

jQuery select list removes all options

孤者浪人 提交于 2019-12-03 08:14:53
问题 I have a <select> list, which has been populated with several options, but want to remove those options to start again. I am using jQuery and have tried the following: $("#selectId").length = 0; But this seems to have no effect. Part of my problem is that I am using Firebug to debug the JavaScript, but the debugger does not break at the breakpoint, so I cannot see what is going on. Should it break when the JavaScript is within the <head> of my HTML file? 回答1: this would do: $('#selectId')

Bug with combination of: jQuery 1.4, ajax/json, Firebug Lite and IE 8

我们两清 提交于 2019-12-03 07:43:51
I had just about concluded that jQuery's ajax calls wouldn't work with JSON data in IE 8, no matter what I tried. I found that I could use the jQuery 1.3.2 library and this fixed the problem, but 1.4 simply would not play ball with JSON ajax requests. Even when the JSON data returned was so simple that there was no question of it being in an invalid format. For example: {"x":"a"} This was regardless of whether I used a Java servlet to return the JSON data, or a simple, canned text file. Regardless of dataType or contentType. Regardless of GET vs POST. Regardless of whether I used $.ajax or $

Running jQuery call in Firebug Console

橙三吉。 提交于 2019-12-03 07:27:31
Sorry, new to Firebug. I really find being able to run javascript in the Firebug console window helpful. However, I don't seem to be able to run jQuery calls in the console. For example, in my executing javascript in my page, I may make the call to get a value: jQuery('#an_element_value').text() However, I cannot execute this in the console. In order to retrieve this value from the page in the console I have to execute: document.getElementById('an_element_value').innerHTML Is there a way to execute jQuery calls and reference page elements through jQuery in the Firebug console? Like others have
