Debugging In Opera

Jun 28, 2006

I really want to make my scripts work in Opera. I really, really do.
But it seems like an uphill struggle. First of all, I can't get ANY
kind of debug output. No error messages in the "javascript console" -
but then, I have never seen ANYTHING in Opera's javascript console. Is
there some kind of voodoo I need to perform in order to make that work?

Then, when Opera doesn't like something about a script (even if it works
fine in Spidermonkey), it will sometimes refuse to load it entirely,
which means I can't even do alert() based debugging. What the hell?

Can anyone give me some insight as to how they go about making their
scripts run properly in Opera? I make a point of sticking to ECMAScript
standards (and then making per-browser exceptions where needed *COUGH
IE*), but Opera just doesn't want to cooperate.

This is in Opera 8, by the way. I haven't upgraded yet, since I don't
use it, and I think more people still use 8 than 9 so that's what I want
to target.

Get IE Debugging Tools?

Mar 5, 2010

Microsoft Script Debugger has been depreciated.

What tools are recommended for debugging JS for IE? I'm only interested in IE7 and 8, but mostly 8.

There are plenty of tools for FF...

Get JS Debugging Messages

Mar 4, 2010

I'm finding (like small syntax errors) in my JS/html which are sometimes hard to spot straight away. For example, when coding python on the web, I usually use try: except: and then use the error function to output what went wrong on the webpage.

Debugging Remote JavaScript

Dec 4, 2006

A newly added, not-quite-wanted function of my job is remotely
debugging JavaScript errors on other people's web applications. I have
tried finding a JavaScript debugger that would allow me to do that, but
other the Microsoft Script Debugger, I couldn't find any other.

Are there such programs? Basically, what I'd like to be able to do is
trace commands step by step and view the values of certain variables.

I was unable to figure out how to get Microsoft Script Debugger to
work. I read the documentation and executed it, but I keep getting
"Syntax error" messages whenever I want to see the value of a variable.
Add to that the fact that I am not a developer and I do not know
JavaScript (other than to read it, which is enough for me to figure out
what the problem is) and you see my problem.

I have read about the option of adding message boxes all over the
place, but this would not work out for me either, since I would need to
make changes to this code on the web server, where I don't have access,
and it would be a lot more tedious.

For those skeptical as to why I still expect to be able to debug
problems:

The problems are caused in most cases by the proxy we add on their web
servers, and they are due to values being changed on the fly. I only
need to find out where the code breaks and read the values of the
variables, which gives me the solution ("do not change this variable").

Debugging Simple Script Under Aptana

Sep 15, 2007

First, is this an appropriate NG for talking about debugging
JavaScript in Aptana?

Assuming it is, I'm trying to get a script to read an external text
file and display the text somehow. The script just dies in the file-
read operation, with no symptom. I tried unsuccessfully to get the
Debugger to run the HTML file.

I put up the following on my personal website:

1. The HTML file: http://home.comcast.net/~CaptQueeg/DemoFileIO.html
2. Some Aptana settings: http://home.comcast.net/~CaptQueeg/...bugSettings.jpg

Did any obvious mistakes jump out at you? Do my Aptana settings
suggest a reason why I can get anything happening under the debugger?

JQuery :: Debugging An Ajax Script?

Dec 23, 2010

I recently changed my commenting system to display comments from newest to oldest (newest first). I also moved my comment form above my comments, like in Youtube.However, I have many JQuery problems when I have 2 or more pages of comments. Here are some of them:

1. If I comment, the last page (oldest) comments are displayed when the comment is submitted.

2. If I "reply" to a comment, the comment form moves below the comments.

Code:

function setup_comment_ajax() {
jQuery(".comment-navigation a").livequery("click", function () {
$link = jQuery(this);

JQuery :: Installing, Using, And Debugging A Plugin (jqPrint)?

Jun 8, 2011

I'm looking for a little help/feedback regarding using a plugin called jqPrint. I haven't used jQuery extensively, and I am new to plugins, so please forgive any novice errors.

First of all, i see on the source page for the plugin [URL].. that it is made for 1.3.x. I assume this does not mean that mean it is incompatible with 1.4.2, which is what my project uses. I have a script with the source code, and I can access a test function. However, I'm running into several problems when trying to to use the primary function of the script.

[Code]...

I'm not quite sure what I'm doing wrong. The script is set up so I can access a test function, but the source function does not work. I would think anyone using the author's script should not need to edit it, but I can't figure out why my project cant' find the jqprint function.

Debugging & Logging A Server Side Script

Aug 28, 2009

I have a couple of server side scripts that keep troubling me. So far I used Visual Studio to debug them, but for some reason I can't put in breakpoints and stuff ... So debugging like I'm used to is not possible. (I'm developing the sites in dreamweaver) I've tried adding a logging function to a flat textfile, but I've been told traditionally writing to a file is not possible in a server side script... how I can best debug such an application? Is it possible to do so in Visual Studio? Another tool?

Debugging Mad Libs, Accessing Text From Input Boxes

May 19, 2011

I've been playing around with a madlibs exercise while trying to learn simple javascript. I have three input boxes and a button display an alert containing the input from the boxes.

Am I right to be assigning variable names to the values from the text boxes and then referencing those variables in my alert?

I've been working on it for hours and can't get past this point.

Debugging A Simple Function - Move The Object - A Paragraph Element Node With Id Message - To The Right

Jan 18, 2010

I'm trying to attempt a simple animation, as indicated by the following code. The intention is to move the object (a paragraph element node with id message) to the right by 200 px and down 100 px, by 1 px a second.

However, there seems to be a bug or my methodology is incomplete as the browser returns the Textvalue of the paragraph without any styling.

Problems With Opera

Jul 23, 2005

<script language="JavaScript1.2" style="text/javascript">
<!--
function checkLocation() {
if (navigator.userAgent.indexOf("Opera")!=-1) type="OP"
else if (document.all) type="IE" // ie 4 & up
else type="XX"
if (type=="IE")
moveNav.style.pixelTop=document.documentElement.sc rollTop
setTimeout("checkLocation()",5);
}
//-->
</script>

This is suppose to keep the Nav bar at the top of an IE browser. (Yes, it
wobbles a little bit, but what can I do?)

With most other browsers, the Nav Bar stays nice and stationary at the top,
thanks to a nice CSS solution. However, with Opera (at least Opera 7.54 that
I have) the nav bar wobbles a bit like I would expect it to in IE, but still
it gets hidden under most scrolling situations. What's the cure for Opera?

Opera 7.11 Reloads *.js

Jul 20, 2005

Has any user of Opera 7.11 noticed that it does not reload all files
when the reload button is clicked? I can click on my html file to cause
Opera to load and start and it's OK. But if I then correct an error in
a *.js file and click reload I often get a javascript console with the
same error that I just corrected and line numbers that refer to the old
file. This has got to be something that I am doing wrong, but I can't
see it.

OnKeyPress In Opera 7.11

Jul 20, 2005

I have included a file below that tests onKeyPress in Opera 7.11. I am
getting peculiar behavior. When the file is first loaded, pressing the
keypad + causes the textarea to get physically larger on the screen, and
pressing the keypad - causes the textarea to get physically smaller. I
click on the scrollbar then this behaviour stops and subsequent
keystrokes are displayed appropriately. Is this some kind of bug in
Opera 7.11? Code:

SetAttribute() In Opera 7.54 Win

Mar 27, 2005

I'm in the process of migrating a script to use DOM core methods but I've hit a roadblock in the aforementioned browser. The following code snippet illustrates what I'm basically trying to do, it really is incredibly basic!

var newimg = document.createElement('img');
newimg.setAttribute('id', 'placeholder');
newimg.setAttribute('src', 'images/large/courtyard.jpg');

I'm then positioning the element on the page using appendChild(). Everything works perfectly on Firefox 1, IE5+, Opera 8, Konqueror 3.3.1 (Linux) but not in Opera 7.54. I suspect the element is being created as associated styling on #placeholder is being applied (just some padding and borders) but the image itself is not being displayed. I assume therefore that the problems lies with setAttribute()?

This seems like the sort of problem that others would have encountered, but I haven't been able to find mention of it anywhere.

FF And Opera JS Problem

Nov 6, 2005

I am using this code:

document.getElementById("p").setAttribute("disabled","true");
to disable a button after user clicks it (this is to make sure user clicks it only once). It is needed to prevent multiple clicks on a button since each click calls a servlet.

This code works in IE but does not in FF and Opera.

Js Works Only In Opera?

Jun 24, 2011

I have this code

[URL]

If you'll use Opera browser, it will display lightbox style animation after clicking on marker on the map. Other browsers are not so kind

Chrome give an error Uncaught TypeError: Object [URL] has no method 'click'

To display animation in bumpbox(lightbox alternative) I use this html code

Code:

<div id="neco" style="display: none">
<a href="clouds.swf" class="bump">clouds</a>
</div>

and this javascript

Code:

google.maps.event.addListener(markerName, 'click', function mojafunkcia() {
document.getElementById("neco").getElementsByTagName("a")[0].click();
})

I assume that html element cannot access that javascript function because it ist nested within other function (please see source code on turie.eu), but I'm not very skilled with javascript, so I'm not sure.

Iframe Resizing On Opera

Jul 23, 2005

the problem is, i have this javascript code in my aspx page that i want
it to work on almost all browsers, especially opera and safari :

function resize(){
displayFrm = document.getElementById("ifrmDisplay");

innerDoc = (displayFrame.contentDocument) ?displayFrm.contentDocument :
displayFrm.contentWindow.document;

objToResize = (displayFrm.style) ? displayFrm.style : displayFrm;

objToResize.height = innerDoc.body.scrollHeight;
}

the code above gets called every time a new page is loaded inside the
iframe (ifrmDisplay) what its doing is resizing the iframe so it can
have the same size as the page inside it, so i can eliminate the need
for vertical scroller for the iframe, i assumed that it works on opera
and IE at the same time, when i tried it out, it worked on IE but not on
opera. after lot of time in researching how i can get workaround this
issue with opera, that is the best possible solution i have and yet it
doesnt work. so i gave up and asking you if you can help me out here ,
coz this is jst driving me crazy!

the problem is im not a javascript expert, to be honest i jst started
doing javascripts about two days ago, that is why im in need for help

by the way, here is inner html for the iframe if its any use

<iframe id="ifrmDisplay" style="Z-INDEX: 99; LEFT: 187px; WIDTH: 567px;
POSITION: absolute; TOP: 136px; HEIGHT: 408px" src="" scrolling="no"

AvailHeight/Width In Opera

Jul 23, 2005

I've noticed that screen.availHeight/availWidth don't return
correct results in Opera 8, meaning that what Opera returns are
the pure screen dimensions, no the actual dimensions due to
taskbars or similar. On the other hand other browsers (MSIE,
Netscape, Mozilla) get this correct.

Opera Bug? -- Disappearing <form> ?!

Jul 23, 2005

In Opera 8.01 (Linux; Build 1204) and in Opera 7.54 (Windows XP; Build 3865),
my form disappears from the HTML markup (below). To summarize:

1) In a <script> block in the <head> I create a form element (part of
object/feature/bug detection).
2) There's a <form> element defined in the <body>, with the id 'theForm'.
3) The onload function tries to access that form, and also counts the
total number of forms in the document. It fails to get a reference
to the form; the count is 0. Code:
