随机漫游文档加入渐进的想法实现

前文：添加顶栏按钮，随机打开文档（随机漫游） - 链滴 (ld246.com)

增加了个后台文件存储已查看的文档 id，初步条件是 7 天内不会刷到重复的文档，我想法是基于随机文档，通过 dn 进一步将文档简练和记忆使用，实现较粗糙，慢慢优化吧

使用该代码块，需要先创建 /data/assets/extConfig/randomList.json 文件，初始文件内容 [] 即可

// 请求函数
function request(url, data = null, method = "POST") {
    return new Promise((resolve, reject) => {
        if (method.toUpperCase() == "POST") {
            fetch(url, {
                method: "POST",
                headers: { "Content-Type": "application/json" },
                body: JSON.stringify(data),
            })
                .then(
                    (data) => resolve(data.json()),
                    (error) => {
                        reject(error);
                    }
                )
                .catch((err) => {
                    console.error("请求失败:", err);
                });
        }
    });
}

function 获取数组里指定元素(id, arr) {
  for (let r in arr) {
    // console.log(12111,r,arr[r])
    if (arr[r].id == id) {
      return arr[r];
    }
  }
}

// 打开随机文档，编辑sql选定范围
async function randomNote() {

    let sql =
    "select distinct root_id from blocks where type='d' and path like '/20211209181026-i3s9wiq%' and fcontent not in ('2021','2022','2023','01','02','03','04','05','06','07','08','09','10','11','12','收集箱【inbox】','Index') order by random()";
  // 查出SQL结果
  let queryRes = await request("/api/query/sql", { stmt: sql });

  //   获取当天日期
  let nowDate = new Date();
  let today =nowDate.getFullYear() +"-" +(nowDate.getMonth() + 1) +"-" +nowDate.getDate();

  let 所有待查看id = [];
  if (queryRes) {
    // let index = Math.floor(Math.random() * queryRes.data.length);
    // console.log(0,queryRes.data[0].root_id)
    for (let r in queryRes.data) {
      // console.log(r)
      所有待查看id.push(queryRes.data[r].root_id);
    }
    console.log(所有待查看id);
    // window.open("siyuan://blocks/" + res.data[index].root_id);
  }

  // 获取已查看ID
  let 已查看数据 = await fetch(`/assets/extConfig/randomList.json`)
    .then(async (res) => {
      if (res.status == 404) {
        alert("需创建/assets/extConfig/randomList.json文件");
      } else {
        return await res.json();
      }
    })
    .then(async (e) => {
      return e;
    });

  //   1. 查出的列表为随机排序的所有id，对比已查看的，无则在已查看里新增ID和日期
  //   2. 如果有，判断时间值，暂定，如果在7天以上的，还是打开
  let 所有已查看id = 已查看数据.map((e) => {
    return e.id;
  });

//   console.log("所有已查看id", 所有已查看id, 所有已查看id.indexOf("111") == -1);

  for (let index in 所有待查看id) {
    let 待查看id = 所有待查看id[index]
    if (所有已查看id.indexOf(待查看id) == -1) {
      // =-1表示不包含
      // 打开文档，添加id
      已查看数据.push({ id: 待查看id, rq: today });
      window.open("siyuan://blocks/" + 待查看id);
      break;
    } else if (
      (new Date(today) -new Date(获取数组里指定元素(待查看id, 已查看数据).rq)) /(1000 * 60 * 60 * 24) >=7 ) {
      // 打开文档，修改id
      for (let r in 已查看数据) {
        if (已查看数据[r].id == 待查看id) {
          已查看数据[r].rq = today;
        }
      }
      window.open("siyuan://blocks/" + 待查看id);
      break;
    }
  }
  console.log("修改过后", 已查看数据);

  //   将已查看数据写入到文件中

  let saveDataBlob = new Blob([JSON.stringify(已查看数据),],{ type: "application/json" });
  let 数据文件 = new File([saveDataBlob], "randomList.json", {lastModified: Date.now(),});
