我有一个表格,在标题中,生成12个单元格从当前日期开始,然后减去一个月,所以:
22 Oct 2014 | 22 Sep 2014 | 22 Aug 2014 etc etc
然后我有一个带有日期列表的JSON文件。我有一个ANgular服务,它检索日期然后,我正在尝试做什么,比较标题中的日期范围,然后计算我的JSON中的项目数,落在日期之间。
这是一个Plunker:http://plnkr.co/edit/8nCKlxRAdtosc0EN2swG?p=preview
HTML:
<table>
<thead>
<tr>
<th></th>
<th ng-repeat="months in getMonths track by $index">{{ months }}</th>
</tr>
</thead>
<tbody>
<tr>
<td></td>
<td ng-repeat="months in getMonths track by $index">
<span ng-repeat="item in filtered = (DateMapping(months))"></span>
<p>{{filtered.length}}</p>
</td>
</tr>
</tbody>
</table>
JS:
因此,输出看起来像:
22 Oct 2014 | 22 Sep 2014 | 22 Aug 2014 etc etc
2 | 5 | 0 etc etc
更新:
$scope.DateMapping = function(months) {
var curDate = new Date(months);
var prevDate = new Date(months);
prevDate = new Date(new Date(prevDate.setMonth(prevDate.getMonth() - 1)).setDate(prevDate.getDate() - 1));
//console.log("curDate: " + curDate);
//console.log("prevDate: " + prevDate);
var jsonEntries = $scope.Dates;
for (var i = 0; i < jsonEntries.length; i++) {
var jsonDate = jsonEntries[i].Date.substring(6, jsonEntries[i].Date.length - 2);
if (jsonDate >= curDate && jsonDate <= prevDate ) {
//PERFORM .push
}
else {
}
}
};
