const jumpToUnreadPage = 'Jump to an unread page';

scrapbox.PageMenu.addMenu({

title: jumpToUnreadPage,

onClick: async () => {

const project = scrapbox.Project.name;

const pages = scrapbox.Project.pages.filter(

page => page.exists && page.title !== scrapbox.Page.title

);

const getNextPage = async () => {

const nextPage = await fetch(/api/pages/${project}/${encodeURIComponent(title)});

return await nextPage.json();

}

const menu = scrapbox.PageMenu(jumpToUnreadPage);

menu.removeAllItems();

menu.emitChange();

let count = 0;

while (true) {

const nextPage = await getNextPage();

const msg = ${++count}: /${project}/${nextPage.title};

menu.addItem({ title: msg, onClick: () => {} });

console.log(msg);

const unreadLine = nextPage.lines.find(line => nextPage.lastAccessed < line.updated);

if (unreadLine) {

const a = document.createElement('a');

a.href = ./${encodeURIComponent(nextPage.title)}#${unreadLine.id};

a.rel = 'route';

document.body.appendChild(a);

a.click();

a.remove();

return;

}

});

location hrefの代わりに<a rel="route">を使ってジャンプすることで、SPAを維持できる

元：if (unreadLine) { location.href = /${project}/${encodeURIComponent(nextPage.title)}#${unreadLine.id}; }

全ページ既読だと無限ループする
