How to load data when scrolling all the way down?

Question

Python

Hello! I have a middleware that sends a photo request (below)

function getPhotos() {
    return dispatch => {
        dispatch(getPhotosBegin());
        return unsplash.photos.listPhotos(1, 15, "latest")  //Первый параметр -  страница, второй количество элементов на странице
            .then(toJson)
            .then(json => {
                dispatch(getPhotosSuccess(json));
            })
            .catch(error => dispatch(getPhotosFailure(error)));
    };
}

The task is to send a new request when the user has scrolled all the way down, show him the next batch of photos. I can't figure out how to do this, please help

Answer 1

There is no python error here. This is your personal mistake. Accept it and once again, with pain in your soul, study at least one page of a python textbook, where they talk about syntax

Answer 2

Quotes inside quotes. Use different quotes inside and outside:"text'quoted'text"

Answer 3

intersectionObserver or catch the position of the "trigger" object relative to the viewport.
The first one does not have support in IE, well, and it doesn’t matter, but there is a polyfill.

Answer 4

fit ?
