How to find the top 5 JavaScript obfuscation practices and tools? Are there tools able to combine multiple .js source files into one combined wholly obfuscated and hopefully compressed .js output file? Is it wise to obfuscate twice? and The top 5 CAPTCHA evaluation tools (don't necessary need to be javascript).
View 1 RepliesI am now seeking tools on javascript obfuscation. I have searched for
several like stunnix, . But the interface is not really neat and sounds
complicated. Is there any open source project doing this ? I need to encrypt
several js and jsp files using javascript. If not an open source, which
other obfuscator you will recommend?
If obfuscation isn't all that good, why does Google obfuscate its
search results' code? Okay, I realize they're a commercial entity and
need to do it. How do they do it?
Could anyone out there decipher and normalize code for a Google search
result page? And despite the obfuscation, why is Google so fast?
I also get the feeling sites like Google and Facebook manage to create
better thumbnails on the fly. Any idea how?
What is the evaluation context of the setTimeout args below? I have a separate Timer instance for each sprite in my program. As coded, "this.Clock" doesn't work.
/*================================================= ===
Timer.js
================================================== ==*/
function Timer(_sprite, _interval) {
var sprite = _sprite;
var interval = _interval;
var isRunning = false;
var timeoutID = false;
this.Clock = function() { // called after setTimout interval
if (isRunning) {
isRunning = sprite.OnClockTick();
if (isRunning)
timeoutID = window.setTimeout("this.Clock()", interval);
else
this.Stop();
}
}
this.Stop = function() {
if (timeoutID) {
window.clearTimeout(timeoutID);
timeoutID = false;
};
isRunning = false;
}
this.SetInterval = function(_interval) {
this.Stop();
interval = _interval;
isRunning = true;
timeoutID = window.setTimeout("this.Clock()",interval);
}
this.Continue = function() {
if (!isRunning) {
isRunning = true;
timeoutID = window.setTimeout("this.Clock()",interval);
}
}
}

Here is an answer for those who are looking for a keystroke evaluation
script that works in Internet Explorer (IE 5.5, 6.0, 7.0 for PC--IE
4.0, 5.2 for Mac), Mozilla Firefox (Windows, Linux, and Apple
Macintosh), Safari, Opera, and other off-brand web browsers.
I have gone through many groups trying to find code that didn't break
in Firefox--yet still worked in other browsers. Although many people
give input on this topic, few are correct in their handling of the
events to give the correct results across the board.
I am a Webmaster, and although I have worked with much JavaScript, I do
not claim to be an expert on this topic--so feel free to post any
improvements that you can make.
Here's the test code, this snippet designed to force numeric-only input
in any browser, with the exception of a couple keys that are still
needed for form navigation (such as Tab--although this can be tailored
to your needs by adding more exceptions):
---SNIP_01---
<script language="JavaScript">
function CheckNumericKeyInfo($char, $mozChar) {
if($mozChar != null) {// Look for a Mozilla-compatible browser
if(($mozChar >= 48 && $mozChar <= 57) || $mozChar == 0 || $char ==
8 || $mozChar == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
else {// Must be an IE-compatible Browser
if(($char >= 48 && $char <= 57) || $char == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
return $RetVal;
}
</script>
---END_01---
This function would then be called as follows:
---SNIP_02---
<input type="text" name="over_figure" id="over_figure" size="5"
onKeyPress="return CheckNumericKeyInfo(event.keyCode, event.which);"
value="">
---END_02---
I have personally tested this on PC, Mac, and Linux systems in every
Web browser that I can get my hands on. It's far easier than the other
scripts that I've found, and you can just add "alert('keyCode: ' +
$char)" to find any other keycodes you might want to allow if you don't
know them off-hand. Obviously there is room to add a larger exception
list if you have need of it, and it might be better to just set $RetVal
to TRUE in the else and add an else if for IE, but my use didn't
require it.
I hope it saves someone some time!
I am a visiting researcher at a laboratory this summer and my
current task is investigating javascript obfuscation techniques. I am
trying to get a relatively large sample of website containing
javascript code so I can analyze it and determine if it is:
1) obfuscated
2) malicious
I have a fairly decent inference what the result will be, but it would
be nice to have statistics on my side. Having said that, I believe it
will be necessary to have a very large sample size to perform my
analysis.
Now for my question, does anyone know if there are any ways to utilize
a web browser or other component to automatically find javascript
samples? Google has not yielded any results, and the code search
merely searches repositories; not exactly what I need.
Short of rolling my own crawler, can anyone offer any suggestions that
will aid me in my task?
I am using metadata plugin. I want to use validation where I have a hidden field that contains hash5 value of captcha text and I have to validate it with what user enters in captcha field, convert that value to hash5 and then compare with the hidden field. How can I do that? I have other fields in the form too and I want this to be added in the script.

I downloaded and installed Securimage's Captcha code, and then my jQuery slideshow (by Jon Raasch) stopped working. I'm new to jQuery and am really a javascript noob to begin with, so I don't know where to begin. I looked at slideshow.js and prototype-1.6.0.2,js to try to find some conflict and I can't find anything obvious. I know that the Captcha code is the problem because when I comment out the <script>, the slideshow starts working again. he site I'm working on is here: [URL]

I use ajax submit for my jquery validation form. I NEED a captcha for the form, being I am getting attacked by bots. I cannot figure out how to do it. I will past my code below.
$('#contact_form2').validate({
submitHandler: function(form) {
var str = $("form").serialize();
$.ajax({
type: "POST",
url: "contactpage.php",
data: str,
success: function(){
$('#contact_form2').html("<div id='message'></div>");
$('#message').html("<h2>Contact Form Submitted!</h2>")
.append("<p>We will be in touch soon.</p>")
.hide()
.fadeIn(1500, function() {
$('#message').append("<img id='checkmark' src='images/check.png' />");
});}});
return false;
}
Here's part of the codes I got from our website. Right now, when someone wants to register on our website, they have to put into the Captcha after they finish all the other information. If the captcha is empty, there would be an alert; if it's wrong, the page would be refreshed, and there would be another alert, and at the same time, all the information would be lost and they have to fill them again. Now the question is, how can I stop the page refreshing itself? All I need is an alert and then you could retype the captcha without losing the other information.
<script type="text/javascript">
function ltrim(stringToTrim) {
return stringToTrim.replace(/^s+/,"");
}
function validateForm()
{
var okSoFar=true

I am implementing Captcha security check on the register page and seem that I am unable to find the Captcha image/picture. Does anyone know where can i download such images?

PS: I am currently doing a project on security of the site and i hope that all the threads started by me will benefit people in this forum. ;)
I'm looking for a solution where I can show hidden parts of a page when a person submits a successful captcha. Of course, the parts of the page that are hidden shouldn't be available for viewing via code. Is this possible to do? Are there any scripts available that enable me to do this without reloading the whole page or loading a new one?

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...

If I get the time, I'll build some tools around them, such as methods of getting triad colours, complementary and split complimentary colours, analogous colours, saturation variations, luminance variations (tints and shades) and hue variations (chromatic variations).
Are there any free scripts out there that act like the tools that this forum use when inserting a message, like to make text bold, or insert link.
View 2 Replies View RelatedIn order of priority, I need the following for Safari:
* a debugger (with watch)
* a console (with errors and command line)
* Web Developer toolbar (edit css, validate local)
* DOM inspector (like Firebug or IE's DOM inspector). Firebug is awesome, though...
* Possibly a source editor
* anything else that is useful (like http://www.squarefree.com/jsenv/ or the other bookmarklets on squarefree.com that work for safari).
Does safari support hasOwnProperty now? What about named functions in object literals? syntax example:
Code:

I subcontracted a programmer who replaced my jquery.js with a different version of jquery. This version breaks my function, but my version breaks the layout. I have a function that works with
Code:
jquery.tools.min.js
But not with
Code:
jquery.js?ver=1.4.2
Here's is my function:
Code:
<SCRIPT type="text/javascript">
$(document).ready(function(){
$('.theVideoLink').click(function(e){
e.preventDefault();
$('#VideoContent').load($(this).attr('href'));
});
});
</script>
I need this code to work with
Code:
jquery.js?ver=1.4.2
But it doesn't. It works with
Code:
jquery.tools.min.js
But this jquery.tools.min.js breaks the layout in IE7&8.
Is there any ofline tools for javascript validation.

I am having problem in validating my form using spry tools. The problem is that if I try to include any other validation other than spry along with spry validation the spry validation does not work.
View 1 Replies View RelatedIs there a way to 'activate' an item in the list of items inside Scrollable? The thing I want to accomplish is this: call the api.seekTo() method inside a piece of javascript (this part works) and then visualy show the user what item in the Scrollable list it was that was sought. I know I can influence the appearance of an item clicked but what I do want is tell the scrollable to activate an item (and scroll if neccecary to bring said item into view). So clicking I understand, telling or programaticaly setting the item _without_ clicking and make it stand out (by using the activeClass property).
But I need the scrollable to goto the particular item, in this case my project is a dj timetable for times, so if its currently 2pm, goto that item in the scroller on start - of course, there's PHP involved, so that'll be used, I've already got the item classed as .active, all I need is the scroller to go to that item automatically.
i downloaded a script from jquery tools which is the above: PHP Code:
$(".scrollable").scrollable();
$(".items img").click(function() {
// see if same thumb is being clicked
if ($(this).hasClass("active")) { return; }
// calclulate large image's URL based on the thumbnail URL (flickr specific)
var url = $(this).attr("src").replace("_t", "");
[Code]...
this doesnt works in i.e
if it's possible to nest tabs inside a scrollable from jQuery Tools. Basically, replacing the page content with a set of tabs. I've tried a few times, and with the jQuery native tabs, there must either be some JS or CSS conflicts that prevent things from working properly.
View 1 Replies View RelatedA little difficult to explain, but here goes:I've combined a couple different jquery scrollable functions to a webpage that I'm creating. URL...for my horizontal scrolling.The problem with the vertical scrolling function is that it relies on the mousewheel and mouse clicks for scrolling and I don't feel it's immediately apparent that the text scrolls. But I really like the effect, so I've added arrows and tried to get the functionality from the vertical scrolling example, but it's not working, except for the down arrow in the content in the very last tab. When you click on an arrow, it currently takes you to the previous or next horizontal section.
I know the answer is in there somewhere, but I'm not sure where to look for it. Here's the javascript file that controls the functionality:URL...
Some history: Although I know that it is considered 'old' technology, I have built hundreds of imagemaps over 10 years for a local photographer who uses a panoramic camera (now a spectacular digital one) to photograph weddings, schools etc. I then pop an imagemap area over each face and add a title (and alt text for IE viewers) that shows up on mouseover to identify the person.
I've been using the jQuery tools library recently and tried changing this tooltip demo which turns an image's title into a tooltip from:
$(document).ready(function() {
$("#demo img[title]").tooltip('#demotip');
To:
$(document).ready(function() {
$("#demo area[title]").tooltip('#demotip');
Thus grabbing the title associated with an area rather than an image.
I just built a quick proof of concept using the image map of a family meeting on one of my sites, and viewed it in Firefox. As expected, on hovering over an area the tooltip popped up at top center of the image, with the title text in it. Wow! GREAT! I thought. ;-)
BUT...
In IE: Tooltip pops up, containing the matching title text, but far away from the clicked area and NOT at top center.
In Opera: No tooltip, browser's title box opens by mouse position, but with out title text, instead it contains the a href link that clicking in the area would go to.
In Chrome: No tooltip, no title.
In Safari: No tooltip, no title.
(BTW All tests were done in current browser versions under Win XP)
I just tried Tero's demo at [URL] in all browsers and it worked fine, in every case the tooltip appeared top center of the image, with the title text in it! So it would seem at first thought to be involved with the way browser manufacturers have built their DOM... But further reading indicates that all post v5 browsers use the same DOM model, so I'm stumped. I've Googled quite a few threads where folk have had js/DOM/imagemaps conflicts, but have found no post resolving the issue.
Since libraries such as jQuery claim to isolate us from browser variances, is it just that imagemaps are considered so 'out of date' that browser manufacturers haven't bothered to update their code to integrate them into the standard DOM? (Bravo FF, 'does it right' again!)
