如何 return 当前日期所在的预定义 daterangepicker 范围？

Question

我在 daterangepicker 实例 (http://www.daterangepicker.com/) 中有 52 个预定义的 moment.js 日期范围。在页面加载时，我希望根据当前日期将选择器设置为正确的范围。

例如，今天的日期范围是第 7 周（2/11/2019 - 2/15/2019）。我希望在页面加载时选择该范围。

我已经阅读了 daterangepicker 文档，但无法弄清楚如何访问 isBetween() momentjs 比较的范围。

//Daterange Picker Setup
var today = moment().format('MM/DD/YYYY');
var start = moment();
var end = moment();

function cb(start, end) {
  $("#reportrange span").html(start.format('MMMM D, YYYY') + ' - ' + end.format('MMMM D, YYYY'));
}

$("#reportrange").daterangepicker({
  startDate: start,
  endDate: end,
  ranges: {

Answer 1

如果你想访问已经初始化的 daterangepicker 的范围，你可以使用 $("#reportrange").data('daterangepicker').ranges.

给定一个 ranges 对象 ({'Week 1: [moment('01/01/2019', 'MM/DD/YYYY'), moment('01/04/2019', 'MM/DD/YYYY')], ... }') 你可以使用类似的东西：

Object.values(ranges).filter((item) => moment().isBetween(item[0], item[1]))

获取当前范围。如果今天不包含在任何范围内（例如在您的样本中的周末），这可能不会给出任何结果。

另一种方法是使用momentjs week()获取一年中的周数，然后获取范围对应的索引（如果范围不代表一年中的所有周，这种方法将失败)

var ranges = {
    'Week 1': [moment('01/01/2019', 'MM/DD/YYYY'), moment('01/04/2019', 'MM/DD/YYYY')],
    'Week 2': [moment('01/07/2019', 'MM/DD/YYYY'), moment('01/11/2019', 'MM/DD/YYYY')],
    'Week 3': [moment('01/14/2019', 'MM/DD/YYYY'), moment('01/18/2019', 'MM/DD/YYYY')],
    'Week 4': [moment('01/21/2019', 'MM/DD/YYYY'), moment('01/25/2019', 'MM/DD/YYYY')],
    'Week 5': [moment('01/28/2019', 'MM/DD/YYYY'), moment('02/01/2019', 'MM/DD/YYYY')],
    'Week 6': [moment('02/04/2019', 'MM/DD/YYYY'), moment('02/08/2019', 'MM/DD/YYYY')],
    'Week 7': [moment('02/11/2019', 'MM/DD/YYYY'), moment('02/15/2019', 'MM/DD/YYYY')],
    'Week 8': [moment('02/19/2019', 'MM/DD/YYYY'), moment('02/22/2019', 'MM/DD/YYYY')],
