示例1: return
return ({ getState, dispatch }, { router }) => {
const { ui } = getState();
if (ui.isScrolling || !ui.selectedStreamId) {
return;
}
const elements = document.getElementsByClassName('entry');
const scrollY = window.scrollY + SCROLL_OFFSET;
for (let i = 0; i < elements.length; i++) {
const element = elements[i] as HTMLElement;
if (element.offsetTop > scrollY) {
dispatch(uiActions.scrollTo(0, element.offsetTop - SCROLL_OFFSET));
return;
}
}
const y = document.documentElement.scrollHeight - window.innerHeight;
if (window.scrollY === y) {
const stream = dispatch(getSelectedStream);
if (stream && stream.continuation) {
dispatch(streamActions.fetchMoreEntries(stream.streamId, stream.continuation, stream.fetchOptions));
}
} else {
dispatch(uiActions.scrollTo(0, y));
}
};示例2: dispatch
