Finding Bugs In Minimized Code?
Mar 7, 2011
We have a js heavy web-ui. In the production environment it runs minimized, composed from 10 or so js files. When we have a js-error of some sort (we have about 100 users and growing) we write the window.onerror information to a database. Only, it is not very helpful since linenumbers mean nothing in the intelligeble code.
Is there a minifier that tags the result that would allow translation of linenumbers? Is there some other method people use to solve this problem?

I have a iframe element which currently has a small amount of javascript that handles the scrolltop and I am trying to add a variable to that which controls the height of the iframe based on the source height. I do not want to set the height of the iframe in CSS because if I use this same method for other iframes and the source height is not the same it will not work.The page with the iframe is here (click on the link on the top of the page to load the iframe):
[URL]
The page I want to load into the iframe is here:
[URL]
The javascript and html for the parent page is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
[code]...
Again, what I need is for the iframe to get the document height from the page that will load into the iframe and then have the iframe height be that exact size. As you can see once you click on the link it is much shorter than the page I am using to load into the iframe.I do not know javascript enough to figure it out and have spent a couple days looking all over the internet and have yet to find something I can incorporate into the javascript I already have.

I have some extensive animation going on in this script. I have all the behavior I want out of this script. A 3D carousel interface, each window in the carousel is a separate UI window. It uses active scrolling for navs and content...like (iphone).The problem is that I have optimized to my best and still cant gain any performance out of IE. It runs pretty fast in FF, and in Safari. I have reversed loops, I have vared all my Math, I have stripped equations, could do more I guess, and I have made attempts at preventing even bubbling. I have minimized the use of <img> tags as well. I have even cached most methods and use a constructor method to create new HTML elements.At this point I am starting to feel like I am getting into techniques and areas of JS I just don't understand well.Here is example of a method I would like to optimize:
this.anim = function () {
var s = Math.sin(s3D.A * .01);
var c = Math.cos(s3D.A * .01);[code]....

getElementById Bugs
There are two getElementById bugs up for discussion:
1. getElementById is case-insensitive but it should be case-sensitive.
2. getElementById searches NAME attributes as well as ID attributes but it should not.
My tests show that IE 6 and down have both bugs, Opera 9.02 has bug #2, Opera 7.54 has neither bug, and FireFox 1.5.0.7 has neither bug.
My proposed solution relies on something I noticed while testing in IE: "document.all" is case-sensitive altho it too searches NAME as well as ID attributes.
I would really appreciate if some different people could help me verify these findings in different browsers and on different platforms.
There has been another proposed solution - but I really don't like removing the ID attribute.

I'm trying to implement getElementsByClass() for the document object
and the Element interface, that supposed to work for HTML, XHTML, SVG
and MathML class attributes (including mixed namespace documents) and I
have it working perfectly in Gecko (tested in Firefox 1.0.6 and Deer
Park Alpha 2). I'm just having some serious problems with IE and a bug
in Opera.
The test [1] is supposed to get a NodeList (an Array() with an item()
method added) of elements by class name and then output an alert()
containing the tagNames of the selected elements.
After a fair bit of testing, I believe the problem is occuring with the
way I'm trying to attach the getElementsByClassName() and hasClassName()
functions to elements in IE using an HTC. It seems to be breaking at
the point within document.getElementsByClassName() where I call
element.hasClassName (line 34 of the script [2]) but my understanding of
this workaround using HTCs [3]] that I'm trying to use is very limited
and I don't understand why it's breaking. Code:

When users manually minimize the website window I need the window to minimize up to a certain point and go no further. for example I need the minimum window size to stop at 800 x 600 and get stuck there even if a user tries to minimize it further.
The code that I am trying to play around with is the following with onresize function but I am not sure how to make it give me what I need.
Code:
<head>
<script>
function OnResizeDocument () {
alert ("The size of the window has changed.");

go to the "Jupiter" graphic on the top left, you'll see that I have a little tab at the bottom of that labeled "Physical". When you click on it, it slides out of the way, exposing a tab labeled "Orbital" and when you click on that one it slides out of the way and exposes a third tab labeled "Atmosphere". These all drive the little spec sheets above- though that's not where the problem lies.The problem is when instead of clicking on the exposed label, you click on the little sliver of the one right behind it, causing the other two tabs to do unintended things. Here's the code:
$(document).ready(function(){
$(".badgeTab-A").click(function() {
$(this).animate({'left':'+=80px'}, 'fast', 'linear');

I have a very simple PHP script that is reading a plain-text CSV file
and parses it out into into a HTML table to display the data. No
biggie.
What I want to do is while keeping the browser window for that page
open and minimized, i want to be able to maximize the window when the
text file has been update. This is a small script that is being used
for some dispatchers at a taxi company and the popup window is
supposed to be their list of customers to pickup. The company has
several dispatchers who are constantly updating a proprietary system,
and this system has a special program that spits out the data for
customers who need to be picked up. Every dispatcher has a link to
this PHP webpage to display the next available pickups. The only
problem is that they want to be able to minimize the browser window
and have it open automatically when a name has either been added or
removed from the pickup list.
Is is possible to integrate a javascript function to do this with PHP?

I have a div which wraps a table. Initially, the div's display attribute is "none", basically I need to find the height of the table in the div, and use that information to render the div to the user. The div is rendered only on the users request.

This is just some functionality missing in the Array object that I'd find very useful...
Array.prototype.inArray=function(oObject){
for(var i in this){
if(this[i]===oObject){
return true;
}
}
return false;
}
to use:
var oObj=new Object();
var aArray=[1,oObj,"string"];
aArray.inArray(1); // returns true
aArray.inArray(oObj); // returns true
aArray.inArray("string"); // returns true
aArray.inArray(2); // returns false

I want to be able to find the height of a div in pixels without defining it in JavaScript. The Div needs to be able to have whatever content in it is required, and it will change without a refresh. I have no idea what could possibly do this, I was hoping somebody with more experience with JavaScript could help me :D
It also really needs to be at least Internet Explorer, Firefox and Opera proof.

Title doesn't really give this thread justice ... I have a content div with an image and text included into it. This same div class is being used multiple times. What I want is to be able to click the image, and have the <p> in that div toggle to show or hide. Here is the XHTML code for the front-end:
<div class="content">
<img src="image_big.gif" alt="image" class="toggle_font" />
<p> Caption for the next image. </p>

I'm trying to make some changes to the Javascript portion of our
corporate intranet site and I'm trying to find if theres a way to find
the User's login id from a Javascript function?
If not, is there a way to run a 'echo %USERNAME%' from DOS command
window and obtain the output. I realize there's an inherent security
risk if Javascript were to allow that.
Am I barking on a completely wrong tree, is NTLM authentication what I
should be looking at?
Basically, I need to get the user id without the user having to supply
it on the page manually. Can this be automated?

How would I access the source of a webpage? I would like to get the source,
then use a regexp to find text on a webpage. For example, retrieving a
counter, or some other text that dynamically changes. I'm implementing this
for firefox.
right now, i have a web page opening that contains that info, but i would
rather have a pop up alert() that shows that info.

Say I have some CSS, which is several hundred lines long, with the
contents in this format:
..foo {
blah
color:#000;
blah
}
..bar {
blah
color:#FFF;
}
where the selectors and their opening braces, their closing braces, and
declarations are each on their own lines (always), how can I replace a
specific declaration (line) given a unique selector and a declaration
property. For example, if I wanted the 'color' declaration property line
in the 'bar' class changed.
At the moment I'm iterating through the CSS one line at a time looking
for the selector and then looking for the declaration property (before I
hit the closing brace).
