[英]Formatting a (JSON) UNIX timestamp in Jade & node.js
I'm getting data from a JSON file, of which one of the elements is a timestamp (last_seen) which returns integers like this: 我从JSON文件中获取数据,其中一个元素是时间戳记(last_seen),该时间戳记返回如下整数:
"id": 4294901761,
"distance": 45,
"last_seen": 1465397445
Right now I'm using Jade & node.js to create a table (utilizing the jQuery plug-in DataTables) which has a column for this element. 现在,我正在使用Jade&node.js创建一个表(利用jQuery插件DataTables),该表具有此元素的列。 I would like for each row to display the according dates and times for the integers being grabbed from the JSON.
我希望每一行显示从JSON抓取的整数的相应日期和时间。 My table gets generated in the following way:
我的表通过以下方式生成:
table.datatable
thead
tr
th ID
th Distance
th Last Seen
tbody
each item, i in uplinkjson.hubs[t].nodes
tr
td= item.id
td= item.distancejson
td= item.last_seen
I'm new to both JavaScript & Jade. 我是JavaScript和Jade的新手。 My JS file looks like this:
我的JS文件如下所示:
var express = require('express');
var router = express.Router();
//ok
/* GET home page. */
router.get('/', function(req, res, next) {
var json = req.uplinkjson;
res.render('uplink', { 'uplinkjson': json});
});
module.exports = router;
Any guidance would be appreciated, thanks! 任何指导将不胜感激,谢谢!
You can use something like this: 您可以使用如下形式:
td #{ new Date(1000 * item.last_seen) }
Which would render this (for my timezone): 哪一个会呈现这个(针对我的时区):
<td>Wed Jun 08 2016 16:50:45 GMT+0200 (CEST)</td>
If you want more control over how it looks, you can use a library like moment
. 如果您想更好地控制外观,可以使用诸如
moment
的库。 If you pass an instance of that module to res.render()
, you can do the formatting directly in Jade: 如果您将该模块的实例传递给
res.render()
,则可以直接在Jade中进行格式化:
var json = req.uplinkjson;
res.render('uplink', {
moment : require('moment'),
uplinkjson : json
});
And in your template: 在您的模板中:
td #{ moment(1000 * item.last_seen).format('YYYY/MM/DD, HH:MM') }
Output: 输出:
<td>2016/06/08, 16:06</td>
