Script for choosing a winner on Instagram (JavaScript Instagram comment picker)
Completely reworked the script for choosing winners in contests for instagram (logic and set of functions), which I wrote earlier. Here is the code:
//MOSTLY WRITTEN BY I. Tolstikov of DMTRVK.RU
//THANKS TO GeorgeCrisan from https://forum.freecodecamp.org/t/how-to-make-math-random-not-repeat-same-numbers/417973/3 for the generateUniqueRandom function
// here you can set it up:
let myAccoutName = "dmrtvk.ru"; //your account name to exclude from selection
let howManyToSelect = 5; //number of winners
let numberOfCommentPagesToOpen = 100; // number times to click on the button
let timeToWaitBetweenClicks = 500; // in milliseconds, set this according to your connection speed, so the browser would have time to load the button to expand the comments list.
// end of setup, lets run it.
let haveIt = [];
(function myLoop(i) {
setTimeout(function() {
try {
document.querySelector('.dCJp8.afkep').click();
console.log('>')
} catch(e) {
console.log('Can find any button to click, moving on.')
mainProcess(howManyToSelect); //how many to select
return;
}
console.log('>'); // your code here
if (--i) myLoop(i); // decrement i and call myLoop again if i > 0
}, timeToWaitBetweenClicks)
})(numberOfCommentPagesToOpen); // pass the number of iterations as an argument
function generateUniqueRandom(maxNr) {
//Generate random number
let random = (Math.random() * maxNr).toFixed();
//Coerce to number by boxing
random = Number(random);
if(!haveIt.includes(random)) {
haveIt.push(random);
return random;
} else {
if(haveIt.length < maxNr) {
//Recursively generate number
return generateUniqueRandom(maxNr);
} else {
console.log('No more numbers available.')
return false;
}
}
}
function mainProcess(howManyToSelect){
let userNameList = document.querySelectorAll(".sqdOP.yWX7d._8A5w5.ZIAjV "); // here goes the selector we search for
console.log(userNameList.length);
nameSet = new Set();
for (let i=0; i<userNameList.length; i++) {
nameSet.add(userNameList[i].firstChild.nodeValue);
console.log(userNameList[i].firstChild.nodeValue);
}
console.log(nameSet.size);
let keys = Array.from(nameSet.keys());
console.log("!!!!!!!!!!!!!!!!!!!!!!!!");
console.log("!!!!!!!!!!!!!!!!!!!!!!!!");
console.log("!!!!!!!!!!!!!!!!!!!!!!!!");
console.log("!!!!!!!!!!!!!!!!!!!!!!!!");
console.log("Selected randomly:");
for (i=0; i<howManyToSelect; i++){ //CHANGE THIS TO THE NUMBER OF WINNERS
//console.log(keys[Math.floor(Math.random() * keys.length)]);
randomNumber = generateUniqueRandom(keys.length);
if (keys[randomNumber] == myAccoutName | keys[randomNumber] == undefined){ //CHANGE THIS TO EXCLUDE YOUR ACCOUNT
i--;
} else {
console.log("№",i+1," —", "@", keys[randomNumber]);
}
}
}Just paste into the browser console and hit enter. Pay attention to the comments in the code: there are several variables at the beginning of the program.
myAccoutName = “dmrtvk.ru”; // your account name to be excluded from selection
howManyToSelect = 5; // how many winners do you need to choose
numberOfCommentPagesToOpen = 100; // how many times to press the + button to load comments (depending on how many comments you have under the publication)
timeToWaitBetweenClicks = 500; // in milliseconds, set in accordance with the speed of your connection so that the browser has time to load the + button, which loads the list of comments.
