Question

我下面有一个有效的代码，请帮助我修复下面的第二个脚本，我想做的是一旦您在取货日期时间选择器中选择了任何日期并在选择字段中选择了持续时间，它将自动根据您从持续时间选择和开始日期中选择的持续时间填写返回日期

第一个代码js代码：（由于默认日期为我们的当前日期，因此可以正常工作）

$(document).ready(function() {

$('#datetimepicker8').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date(), defaultDate : Date.now() });
$('#datetimepicker9').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date()});

$('select[name = sas]').on('change', function() {

    var futureDate = new Date(Date.now());
    futureDate.setMonth(futureDate.getMonth() + parseInt(this.value));
    $('#datetimepicker9').data("DateTimePicker").date(futureDate);

});
})

第二个JS代码不起作用

$(document).ready(function() {

    $('#datetimepicker8').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date()});
    $('#datetimepicker9').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date()});

    $('select[name = sas]').on('change', function() {

        //start date
        $('#datetimepicker8').data("DateTimePicker").date(Date.now());

        //future date
        var futureDate = new Date(Date.now());
        futureDate.setMonth(futureDate.getMonth() + parseInt(this.value));
        $('#datetimepicker9').data("DateTimePicker").date(futureDate);

    });

})

$（document）.ready（function（）{

$('#datetimepicker8').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date() }); 
$('#datetimepicker9').datetimepicker({ sideBySide: true, toolbarPlacement: "bottom", showClose: true, stepping: 30, minDate: new Date()});                                    

$('select[name = sas]').on('change', function() {

    //start date
   var objs = $('#datetimepicker8').data('DateTimePicker').date()


    //future date

     var futureDate = new Date(objs);
    futureDate.setMonth(futureDate.getMonth() + parseInt(this.value));
    $('#datetimepicker9').data("DateTimePicker").date(futureDate);

});

}）
