我有波斯日期的数组,希望按周分组日期。 例如,我有以下数组:
[
"1396-10-11 09:07:21",
"1396-10-10 10:03:51",
"1396-10-07 02:07:02",
"1396-11-27 08:02:45",
"1396-11-19 01:02:32",
"1396-12-01 22:13:21",
"1396-02-12 09:07:21",
"1396-05-18 04:02:29",
"1396-05-21 14:01:42",
"1396-07-11 01:16:29"
]
我希望按周分组日期。
我写了下面的代码,但效果不好:
Array.prototype.groupBy = function(prop) {
return this.reduce(function(groups, item) {
var val = item[prop];
groups[val] = groups[val] || [];
groups[val].push(item);
return groups;
}, {});
}
const formatted = dates.map(elem => {
return {
numberOfWeek: moment(elem.date, 'jYYYY-jMM-jDD').startOf('jMonth').jWeek(),
date: moment(elem.date, 'jYYYY-jMM-jDD').format('jYYYY-jMM-jDD'),
score: elem.score
};
});
