Daterangepicker.js预定义日期范围的OnChange事件

Question

我正在尝试找出如何使用onChange库在此选择器中使用daterangerpicker.js事件，我已经在DateRangePicker中进行了搜索，但是关于预定义的问题没有问题日期范围。

请帮助我，为此选择器使用onChange事件的其他方法是什么？

$(function() {

    var start = moment().subtract(29, '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);

});

Answer 1

如documentation中所述，您可以使用apply.daterangepicker事件来检测用户是否更改了日期范围。

$(function() {

    var start = moment().subtract(29, '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);
    
    // The event listener here.
    $('#reportrange').on('apply.daterangepicker', (e, picker) => {
      console.log('The value has changed.');
    });

    cb(start, end);

});
