DaterangePicker如何获取预定义日期范围的值

Question

我想获取我的预定义日期范围的值 daterangepicker

我尝试用.val()和.text()，但不工作，请参见下面的代码

$(document).ready(function() {

  console.log($('#reportrange').find(":selected").val());

});

$(function() {

  var start = moment().subtract(6, 'days');

  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: {

      'Today': [moment(), moment()],

      'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],

      'Last 7 Days': [moment().subtract(6, 'days'), moment()],

      'Last 30 Days': [moment().subtract(29, 'days'), moment()],

      'This Month': [moment().startOf('month'), moment().endOf('month')],

      'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]

    }

  }, cb);

  cb(start, end);

});
