JavaScript Code for Adding a Website Uptime Timer
7,163 0
This site was established about twenty days ago. That is not a very long time, after all, it has only just begun, so I thought I would write an online timer to record how long the website has been running. Enough talk—let's get started.
First, I thought of using JavaScript to define the time and then using HTML to output it. The most troublesome part is mainly the time calculation. Here is the code:
HTML Code
This site has been running steadily: <span id="htmer_time"></span>
JavaScript Code
JavaScript 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);
Usage Instructions
- Create a
time.jsfile and write the JavaScript code into it. - Place the
time.jsfile in the website root directory (or any accessible directory—as long as you remember where it is). - Reference this JavaScript file in the website header.
- Write the HTML code wherever you need to display the running time.
