Spam messages to WhatsApp counting from 0

whatsapp_sendMSG.js

// Are you new to Javascript?
//Just copy, open firefox (did not work on Google Chrome for me)
//press f12, go console tab, paste, change according to instructions and press enter
//Thank you rafaelxavierborges  for providing the message sending code
//I have just turned it into a spammer that counts from 0 and send the next number every second
var t=0; //what is the first number you want to send
var i=1; //delay in seconds
setInterval(function(){ 
	window.InputEvent = window.Event || window.InputEvent; 
	var d = new Date(); 
	var event = new InputEvent('input', {bubbles: true}); 
	var textbox = $('div._2S1VP'); 
	textbox.textContent = t; //if you want to send something else change it in here
	textbox.dispatchEvent(event); $("button._35EW6").click();
	t++; //want to get fancy and send multiples of 2? change to t=t*2; for example (must start counting at one then duh)
  i=i*1000;
}, i);

@vbrodrigo pra fazer isso só se a pessoa tiver o Tamppermonkey (extensão pro Chrome) instalada no Pc dela.

Sim, mas mesmo usando o Tamppermonkey ou console mesmo. Vejo diversos scripts, mas aparentemente nenhum deles permite iniciar uma conversa com um número que não esteja na lista de contatos.

como fazer para ir selecionando outros usuários ?

a little improvement from above, just more specifically take the textbox.

var delay = 0;
var message = prompt("Send Message : ");
setInterval(function () {
    window.InputEvent = window.Event || window.InputEvent;
    var event = new InputEvent('input', {
        bubbles: true
    });
    var textbox = $('div._2S1VP[data-tab="1"]');
    textbox.textContent = message;
    textbox.dispatchEvent(event);
    $("button._35EW6").click();
}, delay * 1000);

Funcionando em 28/04/2020

var delay = 0;
var message = prompt("Send Message : ");
setInterval(function () {
window.InputEvent = window.Event || window.InputEvent;
var event = new InputEvent('input', {
bubbles: true
});
var textbox = document.querySelector('div._2S1VP[data-tab="1"]');
textbox.textContent = message;
textbox.dispatchEvent(event);
document.querySelector("button._35EW6").click();
// $("button._35EW6").click();
}, delay * 1000);

Work in 11-02-2021

`
var delay = 3000; //delay in seconds
var message = prompt("Insira a mensagem: ");
textbox = $('._1hRBM').querySelectorAll('._1awRl')[0];

setInterval(function(){
window.InputEvent = window.Event || window.InputEvent;
var event = new InputEvent('input', {
bubbles: true
});
textbox.textContent = message;
textbox.dispatchEvent(event);
document.getElementsByClassName('_2Ujuu')[0].click();
}, delay);
`

How do you recognize the classes of the textbox and the button?
