我想在 resultLog 中为我的对象添加键和值，我尝试了几种不同的方法，但没有让它起作用。（进一步了解我想要实现的目标）。

到目前为止，这是我的输出：

我已经将我的数组推入对象并添加了键......但现在我卡住了。

let result = [5, 4, 1, 1];
let resultLog = [];

for (let i = 0; i < result.length - 1; i += 2) {
  resultLog.push({ pageViews: result[i], visitors: result[i + 1] });
}
console.log(resultLog);
// output [{pageViews: 5, visitors: 4},{ pageViews: 1, visitors: 1}]

我需要为每个对象添加键和值，但我该怎么做呢？我已经看过.splice或.unshift但无法让它工作。

这就是我希望它看起来的样子：

let result = [
  { url: "/contac.html", pageViews: 5, visitors: 4 },
  { url: "/home.html", pageViews: 1, visitors: 1 }
];

console.log(result)
console.table(result);

这是我提取每个 url 的唯一用户数和 pageView 数的数组。

const filtered =[
"|2019-03-01 09:00:00UTC |/contact.html |12345 |", 
"|2019-03-01 09:00:00UTC |/contact.html |12346 |",
"|2019-03-01 10:00:00UTC |/contact.html |12345 |", 
"|2019-03-01 10:30:00UTC |/home.html    |12347 |", 
"|2019-03-01 11:00:00UTC |/contact.html |12347 |", 
"|2019-03-02 11:00:00UTC |/contact.html |12348 |"]

1.statistics页面浏览量和访问者

 const pageDict = filtered.reduce((prev, cur) => {
    // remove first `|` and last `|`
    const record = cur.replace(/(^\|)|(\|$)/g, '');
    const [time, url, userId] = record.split('|').map((v) => v.trim());
    if (url in prev) {
        prev[url].pageViews++;
        prev[url].visitors.add(userId);
    } else {
        // if url not in prev, init 
        prev[url] = {
            pageViews: 1,
            visitors: new Set([userId]),
        }
    }
    return prev;
}, {});

2.格式化数据

  const result = Object.entries(pageDict).map(([key, value]) => {
    const { pageViews, visitors } = value;
    return {
        url: key,
        pageViews: pageViews,
        visitors: visitors.size,
    }
})
console.log(result);

  1. 打印结果是：

       [
 { url: '/contact.html', pageViews: 5, visitors: 4 },
 { url: '/home.html', pageViews: 1, visitors: 1 }]

你可以试试这个

var obj= {array:[]};
for (let i = 0; i < result.length - 1; i += 2) {
  obj.array.push({ pageViews: result[i], visitors: result[i + 1] });
}
