This is weird, I have this statement in js code:
alert ( "Hello #name , your account will be activated at #date".match(/#{1}[\w_]+/g) );
When I run the code from the file (opening the file using browser)
I get
[hello,name,your,account,be,activated,date]
But when I run it on the chrome developer console
I get:
[#name,#date]
what is happening here? same code d/t result
update:
As #funkwurm tried to mention on the comment there is a change on the code when I inspect the page using chrome developer tool.
match(/#{1}[\w_]+/g) was changed to match(/\[\w_]+/g)
I am using Grails framework so I thought using the slashy syntax (/ /) was causing the problem because Grails also uses that syntax ( due to conflict).
so changed it to
var pattern = new RegExp("#{1}[\\w_]+","g");
alert ( "Hello #name , your account will be activated at #date".match(pattern) );
but still no effect, and when I do alert(pattern) I get /\[\w_]+/g still without the #.
Thanks
As I tried to mention on the update the problem was the # character was missing when inspecting it using chrome developer tool ( Thanks #Lee Kowalkowski for the insight).
I tried escaping it but still did not work.
Here is the solution I came up with:
var pattern = new RegExp(String.fromCharCode(64)+"{1}[\\w_]+","g"); //64 is ascii value of #
Still eager to know why # character was missing

I want to use HtmlUnit (v2.21) to get some search result pages from google. This requires me to click on "people also looked for" link when searching for a person (right side, see example link), which triggers some JavaScript and changes the content of the current page. But this gives me an JavaScript Wrapper Exception (see below).
Clickable example link: https://www.google.de/search?ie=UTF-8&safe=off&q=nicki+minaj
Simple TestCase with errors:
String url = "https://www.google.de/search?ie=UTF-8&safe=off&q=nicki+minaj";
WebClient client = new WebClient(BrowserVersion.BEST_SUPPORTED);
HtmlPage page = client.getPage(url);
HtmlElement link = page.getFirstByXPath("//a[#class='_Zjg']");
HtmlPage newPage = link.click(); //throws exception
this.storeResultFile(newPage.asXml(), "test");
client.close();
Result:
net.sourceforge.htmlunit.corejs.javascript.WrappedException: Wrapped java.lang.NullPointerException

I stored the xml of the "page" object and made sure that the XPath expression is valid and has results.
Anybody got any ideas?
Looks like the JavaScript-Engine (based on Rhino) is very easy to upset and quits on some script-issues, where other browsers are still able to run the script.
I dont know if there is a mistake in the scripts from google, but these two lines solved it for me:
JavaScriptEngine engine = client.getJavaScriptEngine();
engine.holdPosponedActions();
Nevertheless, when running multiple htmlunit-objects in multiple threads it is still possible to get accross this error. This is more a workaround than a solution.
I have this code in JavaScript:
[(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]
In the console, it will return
Array [ "filter" ]
And how can I decode a lot of text that’s similar to the text above? E.g.:
[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]][([][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+
(!![]+[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+
(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+
([][[]]+[])[+!+[]]+(![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[+!+[]]+([][[]]+[])[+[]]+([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[][(![]+[])[+[]]+
([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+
(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]])[+!+[]+[+[]]]+(!![]+[])[+!+[]]]
I want to see the plain script.
I have seen many decoding attempts around, but none that work reliably. The easiest way I have found to decode Non Alphanumeric Javascript is with Chrome.
Open Chrome > Go to jsfuck.com > paste the code you would like to decode in the window > hit Run This.
Then open the Console, in the case of your specific code from PasteBin there will be an error:
Uncaught TypeError: Cannot read property 'innerHTML' of null
To the right of the error, click the line number link, and the code will be revealed. The result is:
(function(){
window.false=document.getElementById('sc').innerHTML;
})
Which explains why you get the error trying to just decode it using JSFuck itself. There is no element with the id sc on their site.
You can use this website to decode jsfuck:
http://codertab.com/jsunfuck
UPDATED
I extracted the decode javascript from the URL above, this is how the decode process work: (javascript)
s = source.slice(0, source.length - 2);
txtResult = eval(s);
Hope it help!
let elem = yourJSFuck
function decode(elem) {
return (/\n(.+)/.exec(eval(elem.replace(/\s+/, "").slice(0, -2)))[1]);
}
console.log(decode(elem))
This should work, the source is from this page
I've the following code to add in userextensions.js file whenever I add the following piece of code it gives me following error
Failed to load user-extensions.js: Syntax Error: Unterminated String Literal
Selenium.prototype.doInsertCKEditor = function(locator,word)
{
this.doWaitForCondition("var x =
Selenium.browserbot.findElementOrNull('//td[#id=\"cke_contents_form
\"]');x != null;", "50000");
this.doRunScript("CKEDITOR.instances['"+locator+"'].setData('"+word
+"');");
the best way to remove this ever I found it to open your script in some javascript editor I did it in Adobe Dreamweaver and it pin pointed the line where actually the problem is and I resolved this
I'm using HTA and in it I have a function that should run a command line with wshell.run , If I'm writing this line in Windows 'Run' util it is working fine, I want it to work also in the HTA with wshell.run.
The line is:
C:\xxxx\xxx\xxx.EXE aaa.psl abc
( The names are xxx just in here - not in the real code.. )
In the javascript code I'm using:
function runCmd()
{
wshShell.exec( "C:\xxxx\xxx\xxx.EXE aaa.psl abc" );
}
The error I got is in the xxx.EXE application says "couldn't open aaa.psl File not found".
Thanks,
Rotem
I'm surprised the xxx.EXE program is running at all. You need to escape those backslashes in the command:
wshShell.Exec( "C:\\xxxx\\xxx\\xxx.EXE aaa.psl abc" );
// ^-----^----^--- here
If you're doing the same thing in the aaa.psl filename, that's your problem.
If you're not passing a full path to the aaa.psl file, then most programs (not all) will expect it to be in the current directory, so you'll want to make sure you've set the current directory correctly (although using absolute paths may be a better option).
Here's an example, for instance, of telling Notepad to edit a file:
shell = WScript.CreateObject("WScript.Shell");
shell.Exec("c:\\windows\\system32\\notepad.exe c:\\temp\\temp.txt");
...or via the current directory:
shell = WScript.CreateObject("WScript.Shell");
shell.CurrentDirectory = "c:\\temp";
shell.Exec("c:\\windows\\system32\\notepad.exe temp.txt");
Okkkk T.J. is the man!! :)
I finnaly made it with your help by replacing exec to run:
This is the final (and working) code:
function runCmd()
{
wshShell.CurrentDirectory = "G:\\xxx\\xxx";
wshShell.run( "xxx.EXE xxx.psl abc" );
}
I'm doing a web where I heavily use AJAX requests to
a XML service. In fact, my web is a front-end with almost
no server whatsoever and uses AJAX to communicate with
the back-end.
Everything was going fine (I developed and tested in Ubuntu 9.04
and Firefox 3.0 as a browser).
One day I decided to see how my web did in IE8...
horror!
Nothing was working as it marvelously did in Firefox.
To be more specific, the Request.HTML's were not working.
As I said, my web relied heavily on that, so nothing worked.
I spent a day trying to get something running but I had no luck..
The only conclusion to which I arrived was that the XML was
incorrectly parsed
(I hope I'm in mistake). Let's get to the code:
var req = new Request.HTML({
url: 'service/Catalog.groovy',
onSuccess: function(responseTree, responseElements) {
var catz = responseElements.filter('category');
catz.each(function(cat){
// cat = $(cat);
var cat_id = cat.get('id');
var subcategory = cat.getElement('subcategory');
alert(cat_id);
alert(cat.get('html'));
alert(subcategory.get('html'));
}
},
onFailure: function(){...}
});
for example, that piece of code.
In firefox, it worked perfectly. It alerted an ID (for example, 7),
then it showed the contents of the category element, for example:
<subcategory id='1'>
<category_id>7</category_id>
<code>ACTIO</code>
<name>Action</name>
</subcategory>
and then it showed the contents of some inner element, in this case:
<category_id>7</category_id>
<code>ACTIO</code>
<name>Action</name>
In IE8, the first alert worked OK (alerted 7)
but the next alert (alert(cat.get('html'));) gave an empty string
and the last threw an Exception... it said something about subcategory
beeing null.
What I concluded with this all is that the elements where parsed
correctly
in Firefox, but in IE8 I only got the tags and the attributes OK,
everything else
was completely wrong (in fact, missing). I mean, the inner content of
all the
elements of the response where gone!
Other fact you could use: this code:
alert(cat.get('tag')); resulted in
Firefox: category
IE8: /category <-----------(?)
hmm what else...
oh yeah... the line you see commented above (cat = $(cat);) was
something
I tried to do to fix this. I read in the mootools Docs that IE needed
to explicitly call
the $ function on elements to get all the Element-magic ... but this
didn't fix anything.
I was so desperate... I even fiddled around with mootools.js code
OK, so...
What I want you, dear mootool-pro's is to help me solve this problem,
for I REALLY need the web to function in IE8, and in fact I chose
mootools to forget about compatibility problems...
ps: if something is not clear, please ASK! I'd appreciate any help :D
I had a similar issue like this sometime ago using jQuery. The problem was that, in IE, the incoming response data needed to be handled by the Microsoft.XMLDOM ActiveX object.
The general steps are to:
Instantiate the ActiveX object.
var oXmlDoc = new ActiveXObject("Microsoft.XMLDOM");
Pass it the incoming response data and load it.
oXmlDoc.loadXML(sXmlResponseData);
Parse it as needed.
