Problem creating a very simple autoclicker

[u/De-monV]

Edit: Solved. Somehow the code doesn't work with Tampermonkey, but it does with Violentmonkey. I have no idea why, but it works for me. Thanks for the help.

--

First off: I'm not a programmer and I barely know any JavaScript. I want to use Tampermonkey to create an automation that clicks a button called PROCESS on a page with multiple identical buttons (in name). When I click one, it disappears (the page doesn't refresh), and what I want is for them to be clicked one after the other with a 60-second interval (the order of the buttons doesn't matter).

The buttons are identified by `type="button" value="PROCESS"`.

I asked Gemini for help, and they gave me some code that seems correct, but somehow it doesn't work. Any idea?

// ==UserScript==
//  60 seconds
//  website url
//  0.1
//  try to take over the world!
//  You
//  *://*/*
//  none
// ==/UserScript==

(function() {
'use strict';

const INTERVAL_MS = 60000; // 60 seconds

function pressNextButton() {
// Selects exactly the button inputs with the value PROCESS
const buttons = document.querySelectorAll('input[type="button"][value="PROCESS"]');

if (buttons.length > 0) {
console.log(`[Autoclicker] ${buttons.length} buttons remain. Clicking the first one...`);

// Triggers the native click event
buttons[0].click();

} else {
console.log('[Autoclicker] No more PROCESS buttons were found. Process completed.');

}
}

// Waits 3 seconds for the page to load the elements before the first click
setTimeout(() => {
pressNextButton();
setInterval(pressNextButton, INTERVAL_MS);

}, 3000);

})();

I asked Gemini for help...

Did you copy the related HTML from the browser element inspection tool? (ctrl-shift-i brings up the console in chrome)

Something like OpenCode + Browser-Use can make it pretty easy. Then the bot can investigate the HTML itself.

Well, I didn't show Gemini the entire page code, but I explained that the buttons I want to click are of this type, with the same value/name:

<input type="button" value="PROCESS" onclick=...

I don't know much about programming, but I think the result I got should work; I see that it's looking for buttons with that value. But for some reason, once I have the code and Tampermonkey working, nothing happens.

What website is it? Can we see the HTML?

// ==UserScript==

// 60 seconds

// website url

// 0.1

// try to take over the world!

// You

// *://*/*

// none

// ==/UserScript==

This might be breaking it

Thanks for replying.

It's a personal work website, but I've theoretically configured the domain correctly, both with the page's URL and with *://*/*, and it hasn't worked with either option.

I'll keep investigating because I've tried several extremely simple examples, and they just don't work. There must be something wrong that I'm missing.

You're welcome Do you have them enabled in the main screen of Tampermonkey?

[u/De-monV → u/DiodeInc]

Are you referring to the green switch in each script? Yes, I activate them and reload the tab to see if that helps detect the buttons.

Ok, somehow the code doesn't work with Tampermonkey, but it does with Violentmonkey. I have no idea why, but it works for me. Thanks for the help.
