Memos API 公告样式滚动效果

Memos - 这篇文章属于一个选集。

效果参考首页

首先需要在网页上合适的位置放置一个 CSS 选择器来展示 Memos，ID 命名为 memos 好了。

核心代码：

<div id="memos" class="memos"></div>

参考： index.debug.html#L124

然后用 JS 把 API 获取到的数据处理成 Json，再展示到 CSS 选择器里：

<!--引入相对时间 Lately 插件-->
<script src="//tokinx.github.io/lately/lately.min.js"></script>

<!--JS 处理 Memos API-->
<script>
    let jsonUrl =
        "https://demo.usememos.com/api/memo?creatorId=101&rowStatus=NORMAL&limit=1&offset=2" +
        "&t=" +
        Date.parse(new Date());

    fetch(jsonUrl)
        .then((res) => res.json())
        .then((resdata) => {
            var result = "",
                resultAll = "",
                data = resdata.data;
            for (var i = 0; i < data.length; i++) {
                var talkTime = new Date(
                    data[i].createdTs * 1000
                ).toLocaleString();
                var talkContent = data[i].content;
                var newtalkContent = talkContent
                    .replace(/```([\s\S]*?)```[\s]*/g, " <code>$1</code> ") //全局匹配代码块
                    .replace(/`([\s\S ]*?)`[\s]*/g, " <code>$1</code> ") //全局匹配内联代码块
                    .replace(/\!\[[\s\S]*?\]\([\s\S]*?\)/g, "🌅") //全局匹配图片
                    .replace(/\[[\s\S]*?\]\([\s\S]*?\)/g, "🔗") //全局匹配连接
                    .replace(
                        /\bhttps?:\/\/(?!\S+(?:jpe?g|png|bmp|gif|webp|jfif|gif))\S+/g,
                        "🔗"
                    ); //全局匹配纯文本连接
                result += `<li class="item"><span class="datetime">${talkTime}</span>： <a href="https://eallion.com/memos/">${newtalkContent}</a></li>`;
            }
            var talkDom = document.querySelector("#memos");
            var talkBefore = `<i class="iconfont icon-line-quote"></i><div class="talk-wrap"><ul class="talk-list">`;
            var talkAfter = `</ul></div>`;
            resultAll = talkBefore + result + talkAfter;
            talkDom.innerHTML = resultAll;

            // 相对时间
            window.Lately && Lately.init({ target: ".datetime" });
        });

    // 滚动效果
    setInterval(function () {
        var talkWrap = document.querySelector(".talk-list");
        var talkItem = talkWrap.querySelectorAll(".item");
        for (i = 0; i < talkItem.length; i++) {
            setTimeout(function () {
                talkWrap.appendChild(talkItem[0]);
            }, 2000);
        }
    }, 2000);
</script>
