获取Bootstrap DateTimePicker的值

Question

我知道还有其他问题，例如我的问题，但是无论我做什么都返回null或undefined。我不知道我要去哪里。

html

<div class="col-sm-6" style="height:130px;">
    <div class="form-group">
        <div class='input-group date' id='datetimepicker10'>
            <input type='text'></input>
            <span class="input-group-addon">
                <span class="glyphicon glyphicon-calendar"></span>
            </span>
        </div>
    </div>
</div>
<div>
    <input type="submit" value="Check" onclick="dateCheck()" />
</div>

javascript

var dates = {};
$(function () {
    $('#datetimepicker10').datetimepicker({
        viewMode: 'years',
        format: 'YYYY-MM-DD'
    });
    //dates.strt = $('#datetimepicker10').datetimepicker().getDate();   //returns UNDEFINED
    //dates.strt = $('#datetimepicker10').find('input').val();          // doesn't display anything
    dates.diffInDays = (new Date($('#datetimepicker10').val()).valueOf()-new Date('2017-04-26').valueOf())/(3600*24*1000);
    dates.str = $('#datetimepicker10').data("DateTimePicker").date();
});
function dateCheck () {
    alert(dates.str);
};

     dates.str = $('#datetimepicker10').val();
      alert(dates.str);
