# **网页添加累计运行时间 JavaScript 代码**

2017.06.07 7,274  0

本站成立差不多二十天了，时间不算太长，毕竟才是刚刚开始，于是我就想着写个在线计时器来给网站记录已运行的时间。废话少说，直接开始吧。

首先我想到了用 **JavaScript** 来定义时间，然后再用 **HTML** 输出。最麻烦的主要还是时间计算问题。下面是代码分享：

## HTML 代码

本站已稳定运行：`<span id="htmer_time"></span>`

## JavaScript 代码

 JavaScript

```
function secondToDate(second) {
    if (!second) {
        return 0;
    }
    var time = new Array(0, 0, 0, 0, 0);
    if (second >= 365 * 24 * 3600) {
        time[0] = parseInt(second / (365 * 24 * 3600));
        second %= 365 * 24 * 3600;
    }
    if (second >= 24 * 3600) {
        time[1] = parseInt(second / (24 * 3600));
        second %= 24 * 3600;
    }
    if (second >= 3600) {
        time[2] = parseInt(second / 3600);
        second %= 3600;
    }
    if (second >= 60) {
        time[3] = parseInt(second / 60);
        second %= 60;
    }
    if (second > 0) {
        time[4] = second;
    }
    return time;
}

function setTime() {
    var create_time = Math.round(new Date(Date.UTC(2017, 04, 18, 2, 0, 0)).getTime() / 1000);
    var timestamp = Math.round((new Date().getTime() + 8 * 60 * 60 * 1000) / 1000);
    currentTime = secondToDate((timestamp - create_time));
    currentTimeHtml = currentTime[0] + '年 ' + currentTime[1] + '天 ' + currentTime[2] + '时 ' + currentTime[3] + '分 ' + currentTime[4] + '秒 ';
    document.getElementById("htmer_time").innerHTML = currentTimeHtml;
}
setInterval(setTime, 1000);
```

## 使用教程

1. 新建 `time.js` 文件，将 JavaScript 代码写入该文件。
2. 将该 `time.js` 文件放到网站根目录（或者是能访问的目录，你自己记住就行）。
3. 在网站头部引用这个 JavaScript 文件。
4. 在需要显示运行时间的地方写上 HTML 代码。
