Chrome 访问 https://z.cn/myk，按 F12（Mac右键“检查元素”），选择 Console 并将下面的脚本复制粘贴然后按回车。脚本是从上面的链接生成的，并且选择的是每 30 秒下载一个文件。

(function() {
    if (!window.location.hash.startsWith('#/home/content/booksAll/dateDsc/')) {
        alert('Need to visit: https://z.cn/myk');
        return;
    };
    const w = ms => new Promise(r => setTimeout(r, ms)),
        n = z => parseInt($('.contentCount_myx').text().match(/(\d+)/g)[z]),
        a = n(0),
        p = x => console.log(x);
    let c = 0,
        v = 0;
    (async function g() {
        let ls = $('.contentTableListRow_myx li'),
            l = ls.length,
            s = n(2);
        if (l < 200 && s < a) {
            window.scrollTo(0, $('body').outerHeight());
        } else {
            for (const j of ls.get()) {
                p('Downloading: ' + $(j).find('div[bo-text="tab.title"]').text());
                $(j).find('button[aria-label="actions"]').click();
                $('#contentAction_download_myx').click();
                $('a[id="dialogButton_ok_myx "').click();
                v += 1;
                p('Total: ' + a + ' Done: ' + v);
                await w(30000);
            }
            c += l;
            if (s == a) {
                p('Done.');
                return;
            } else {

            }
        }
        await w(2000);
        await g();
    })()
