我有一个数组，我想用数组中的字段进行排序，但它不起作用
var data = [{tm: "09:00", tr: "30.34", rd: "73.23"},
{tm: "09:10", tr: "30.45", rd: "70.77"},
{tm: "09:50", tr: "29.95", rd: "75.70"},
{tm: "09:40", tr: "29.95", rd: "75.70"},
{tm: "01:50", tr: "29.95", rd: "75.70"},
{tm: "02:30", tr: "29.95", rd: "75.70"},
{tm: "04:50", tr: "29.95", rd: "75.70"},
{tm: "10:00", tr: "30.05", rd: "76.20"}];
我需要使用 tm 字段对其进行排序，以便排序后数据将采用这种格式
0 tm: 01.50
1 tm: 02.30
2 tm: 04.50
3 tm: 09.00
4 tm: 09.10
5 tm: 09.40
6 tm: 09.50
7 tm: 10.00
我试过了
data.sort(function(a, b){return a.tm - b.tm});
它不起作用任何帮助将不胜感激谢谢
最佳答案
HH:MM 本质上是可排序的，因此传递给 localeCompare 将按预期工作。
var data = [{tm: "09:00", tr: "30.34", rd: "73.23"},
{tm: "09:10", tr: "30.45", rd: "70.77"},
{tm: "09:50", tr: "29.95", rd: "75.70"},
{tm: "09:40", tr: "29.95", rd: "75.70"},
{tm: "01:50", tr: "29.95", rd: "75.70"},
{tm: "02:30", tr: "29.95", rd: "75.70"},
{tm: "04:50", tr: "29.95", rd: "75.70"},
{tm: "10:00", tr: "30.05", rd: "76.20"}];
data.sort((a, b) => a.tm.localeCompare(b.tm));
