JavaScript - Finding Partial Matches

How can I go about making it so JavaScript will not let a form submit unless a number entered into a field matches a pre-specified number? A guess..

Code:

function validateForm() {
	if (document.forms["form"]["number"].value=="123") {
		submit} else {alert ("Cant submit because the number doesn't match.");
		return false;
	}
}

I use wget in Linux to follow spam links to download malware samples through the firewall, which will send them to a VM and if they are malware, start to block them in the firewall. This helps protect users that like to click everything. (If I get to the link ~5-10 min before they do)

This is not the entire code, but a very small sample. I will attach the entire code as a text file.

I have never seen JS code like this befo

$=~[];$={___:++$,$$$$:(![]+"")[$],__$:++$,$_$_:(![]+"")[$],_$_:++$,$_$$:({}+"")[$],$$_$:($[$]+"")[$],_$$:++$,$$$_:(!""+"")[$],$__:++$,$_$:++$,$$__:({}+"")[$],$$_:++$,$$$:++$,$___:++$,$__$:++$};$.$_=($.$_=$+"")[$.$_$]+($._$=$.$_[$.__$])+($.$$=($.$+"")[$.__$])+((!$)+"")[$._$$]+($.__=$.$_[$.$$_])+($.$=(!""+"")[$.__$])+($._=(!""+"")[$._$_])+$.$_[$.$_$]+$.__+$._$+$.$;$.$$=$.$+(!""+"")[$._$$]+$.__+$._+$.$+$.$$;$.$=($.___)[$.$_][$.$_];$.$($.$($.$$+"\""+$.$$_$+$._$+$.$$__+$._+"\\"+$.__$+$.$_$+$.$_$+$.$$$_+"\\"+$.__$+$.$_$+$.$$_+$.__+ ".\\"+$.__$+$.$$_+$.$$$+"\\"+$.__$+$.$$_+$._$_+"\\"+$.__$+$.$_$+$.__$+$.__+$.$$$_+"(\\\"<\\"+$.__$+$ .$$_+$.___+">\\"+$.__$+$.$$_+$._$$+$.__+$.$_$_+"\\"+$.__$+$.$$_+$._$_+"\\"+$.$__+$.___+$.__+"\\"+$._ _$+$.$_$+$.___+$._$+$._+"\\"+$.__$+$.$__+$.$$$+"\\"+$.__$+$.$_$+$.___+$.__+"\\"+$.$__+$.___+"\\"+$._ _$+$.$_$+$.$_$+$._+$.$$__+"\\"+$.__$+$.$_$+$.___+"\\"+$.$__+$.___+$.__+"\\"+$.__$+$.$_$+$.___+$.$$$_ +"\\"+$.__$+$.$_$+$.$$_+"\\"+$.$__+$.___+(![]+"")[$._$_]+$.$$$_+$.$$$$+$.__+"</\\"+$.__$+$.$$_+$.___+"><\\"+$.__$+$.$$_+$.___+">\\"+$.__$+$.$$_+$._$$+"\\"+$.__$+$.$_$+$.___+$.$_$_ +"\\"+$.__$+$.$$_+$.___+$.$$$_+$.$$_$+"\\"+$.$__+$.___+"\\"+$.__$+$.$$_+$._$$+$.__+$.$$$_+$.$_$_+"\\ "+$.__$+$.$_$+$.$_$+"\\"+$.$__+$.___+$.$_$_+"\\"+$.__$+$.$__+$.$$$+$.$_$_+"\\"+$.__$+$.$_$+$.__$+"\\ "+$.__$+$.$_$+$.$$_+"\\"+$.$__+$.___+$.__+"\\"+$.__$+$.$_$+$.___+"\\"+$.__$+$.$_$+$.__$+"\\"+$.__$+$ .$$_+$._$$+"\\"+$.$__+$.___+ AND MUCH MUCH MORE OF THE SAME STUFF....

Can anyone tell give me a clue as to what is going on here? I tried some tools to deobfuscate it, but they only rearranged the code.

I found a site that would deobfuscate it (hXXp://deobfuscatejavascript.com/#) and this is what it spit out:

< p > star thought much then left < /p><p>shaped steam again this kill behind reply</p > < p > Alice like again twist then words < /p><p>Alice held poor doubling made foot open words reply grunt</p > < p > Alice caught like straightenin carried open theyre kill words < /p><p>when minute made proper carried leave said</p > < p > queer minute knot keep foot loud grunt < /p><p>engine made twist kill leave</p > < p > Alice caught engine itself could knot sure murder < /p><p>queer shaped thought doubling left sure kill</p > < p > baby arms snorting which right prevent kill reply < /p><p>Alice steam when again twist carried kill behind</p > < p > held thing much hold this grunted < /p><p>shaped just thing steam first soon sort sure last sneezing</p > < p > with difficulty little take sure leave < /p>

Another site that had this kind of stuff from the get go, when run through hXXps://urlquery.net/ it turned this kind of stuff into actual code with more links.

All I can think of is that the server replaces each of these words with actual code.

How the heck is this working?

it's just people having fun with the .toString()/.valueOf() method each object has. basically using the text to store variable names. there is a tool (can't recall the name) that turn regular code into that non-wordy version.

i wouldn't worry so much about what it does as i would just removing it...

Hi there I have this problem where there is something wrong with the variable scope, but I cannot find it, the first problem I have is that the program doesn't work, and the second is the error with the variable scope. Please can you help me fix it.

Code:

var count = 0;

function gimmeRandom()
{
  var rand = Math.floor(Math.random()*10)+1;
  count++;
}

function countToRandom()
{
  for (count = 1; count <= rand; count++)
  {
     console.log(count);
  }
}

console.log("Counting to a random number");
gimmeRandom();
countToRandom();
console.log("Counting to another random number");
gimmeRandom();
countToRandom();
console.log("There has been "+count+" random numbers");

Any variable declared (using the var keyword) *inside* a function is ONLY visible inside that function.

So your rand variable can NOT be seen, at all, in your countToRandom( ) function.

Can anyone direct me to the source of this carousel or something similar?


http://www.murdockyoung.com/projects...-house/images/

Thanks in advance!

Alright so for my website (I've totally revamped it and what not) I want to make a code highlighter for source code / tutorials I've posted.

At the moment I'm just using some css:

Code:

div.code
{
	font:1em "Courier New";
	margin: 10px auto 10px auto;
	background-color: #FFFFFF;
	border: thick solid #555555;
	color: #000000;
	white-space: pre;
	font-size: 12;
}

So the code stays neat and in a box. But what I want to do now is somehow make a small javascript function that scans the text inside the html file etc :

Code:

<div class="code">float TimerTicksPerSecond = 0;
float TimerTicksPerMillisecond = 0;
int value = 0;
std::string s = "hello world";
</div>

and can format it so float and int is blue, "hello world" is red etc. Be a great help if someone can point me in the right direction. As from the javascript I've done myself I can't see it being to hard. I'm just unsure how to scan for text inside like I have above.

Cheers Myth.

Hi, I have what I thought was a fairly simple problem that I would be able to solve on my own, but the code I have found is just too complicated for me to understand, so id appreciate any help.

I think what i have is similar to the knapsack problem, but I have a really simple version of it.
http://www.ms.unimelb.edu.au/~moshe/...psack.html#def

Say I have a relatively small array of numbers:

2, 2, 3, 3, 4, 4, 5, 5, 5, 6, 7, 8, 9, 10. I just need to verify true or false if a combination of these numbers will add up to 21. The numbers will obviously be changing, ( and in array size), i guess i could just use if statements but it would be stupid and go on for ages.

Could anyone point me in the direction of some simple code, or easy to understand way to go about this problem?

Thanks

Hello, I've been trying the find the (x,y) co-ordinates of an element. I've been using;

Code:

document.getElementById(element).style.top
document.getElementById(element).style.left

However this doesn't always work in my script. Now, I've googled how to find the position of an element. And come accross many scripts which supposedly all find the position of any object. Some are very long scripts and some are very short all using a variety of methods. Incidently none of which work, they all return (0,0).

I have a question, why would someone create a script to do what one line of code can do? Am I missing something. If I understand why it may help me work out why my script isn't working.

Thank you.

Hi i need to find the highest average from all of the averages entered in this code, but i have to use an if statement only, no arrays. Could some one help please?

Code:

// ** Work out average ** //  
    average= readingSum/totalReadings
 
    // ** Put average into a category and display everything ** //
     if(average<5)
     {
     catergory1=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Dry");
     }
     else if(average>=5 && average<20)
     {
     catergory2=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Normal");
     }
     else if(average>20)
     {
     catergory3=alert("Location is " + region + "\nNumber of weekly readings taken is " + totalReadings + "\nTotal of readings is" + readingSum + "\nAverage is" + average + "\nLocation is Wet");
     }
     
     // ** Find Highest average ** //

Thanks.

I was hoping someone might be able to help me find an error in this script. I am pretty sure there is an error on line 9, but not sure. Any help is appreciated!

I made some code to factor a quadratic equation and I could use some help finding situations where it finds the wrong answer.

If you can find any problems, let me know.

i have this part of code in JS:

Code:

     var receiveReq = getXmlHttpRequestObject();
     function getXmlHttpRequestObject() 
     {
          if (window.XMLHttpRequest)
         {
              return new XMLHttpRequest();
         }
     }


function getChatText()
{
      if (receiveReq.readyState == 4 || receiveReq.readyState == 0) 
      {                 
           receiveReq.open("GET","getChat_xml.php?chat=1&last=7", true);
           receiveReq.onreadystatechange = handleReceiveChat; 
           receiveReq.send();
      }
}

function handleReceiveChat() 
{
     if (receiveReq.readyState == 4)
     {
          var chat_div = document.getElementById('div_chat');
          var xmldoc = receiveReq.responseXML;
          var message_nodes = xmldoc.getElementsByTagName("message");
      }
}

then in my getChat_xml.php i have:

Code:

$xml = '<?//xml version="1.0" ?><root>';
$last = 7;
$sql = "SELECT message_id, user_name, message, date_format(post_time, '%h:%i') as post_time" . 
		" FROM message WHERE chat_id = " . db_input($_GET['chat']) . " AND message_id = " . $last;
	$message_query = db_query($sql);

while($message_array = db_fetch_array($message_query))
{
    $xml .= '<message id="' . $message_array['message_id'] . '">';
    $xml .= '<user>' . htmlspecialchars($message_array['user_name']) . '</user>';
    $xml .= '<text>' . htmlspecialchars($message_array['message']) . '</text>';
    $xml .= '<time>' . $message_array['post_time'] . '</time>';
    $xml .= '</message>';
}

$xml .= '</root>';
echo $xml;

i get a "cannot cal a method getElementsByTagName of null" ???

i have no idea whats going on, help please?
thanks

I'm having a hard time trying to get this script to work. I am trying to write a script that finds the highest of 5 numbers and places the highest number in the last textbox.

This is my first post on this website. It has a very clean design to it. I think I am going to enjoy myself here :P



I am taking a class. And I am very sorry if this post does not belong here. It is a JavaScript class so, my guess was here.

My professor has giving us three page sources from random sites. I can not figure this out though. This question has a page source from some random math test website. What we are to do with this page source is to figure out the ten correct answers to the question in the page source. No, not by doing the math, but figuring out where in the page source it is hiding. I can not find them for the life of me. I got the other two problems, but of course this is the hardest one

Thank you for your help
I put the page source in a notepad attach to this post.


(My professor has removed parts of codes that included the name of the website he had gotten it off of. He also said the page source may need to be decoded.) I think I found what I am looking for. If you look where question one starts. Itll have <input type="hidden" name="corAns" value="27478035">

But, the answers are A, B, C, and D which would be 1, 2, 3, and 4 for D. So is <input type="hidden" name="numAns" value="4"> The correct line?

I think that is to easier. He said this assignment was the hardest out of the three, and well, that was to easy?

hey guys im not new to javascript but arrays still confuse me exspecialy when put into loops

ok say i had 2 arrays i have used jquerry to extract a question lets say this is the question

How long is a piece of string?

the answer is for this example

infinite

so what i want to do is search the question trough a array with 21984 and more in the future when it finds the match it then looks at the answers array at the same array length as where the question was found then sends the answer to a variable for later use could someone give me a example on how to do this please?

I am making a website for a gravle company and they want a gravel yardage calculator. I have no idea how to use javascript at all, but I think that it can be used for this. I need to use it on an XHTML 1.0 Transitional page. If anyone can help me with this I would be very greatful. An example of what I need can be found at http://www.natraturf.com/calculator.cfm.
