I have a question about how to send data to websites

Hello, so I want to make on a website (A) a button where you insert a number and on another website (B) a div is created with the number you input. My question is what should I look into/learn to do that? I know HTML, CSS, JS. The websites will be hosted online. Thank you.

More context:

I wanna make a website for a restaurant's menu and include a "call a waiter" button, and my idea is to have a tablet in the waiter's area where when a customer clicks and inputs their table a

is created on the waiter's website with the table number.

How can I check if an image in a local folder exists with plain JavaScript?

Basically my question is how can I do this? Anywhere I looked I couldn't find answers.

for(var i = 0; i < 4; i++){
var img = document.createElement("img");
img.style.src = img/${i}.png;

if(img exists)
     document.body.appendChild(img);

}
Also is this possible somehow?
for( i = 0; i < how many images are inside folder; i++)
