引导日期时间选择器不适用于角度6或7

我从角度6创建一个普通的反应

<div class="input-group date">
    <input type="text" class="form-control m-input m_datetimepicker"  placeholder="Select auction start date & time" 
        formControlName="addStartDate" [ngClass]="{ 'is-invalid': addForm.get('addStartDate').touched && addForm.get('addStartDate').invalid }" />
    <div class="input-group-append">
        <span class="input-group-text"><i class="la la-calendar-check-o glyphicon-th"></i></span>
    </div>
    <div class="invalid-feedback">
        <div>* Time start date & time is required</div>
    </div>
</div>

因此,我使用基本jquery初始化日期时间选择器

$("body").on("focus", ".m_datetimepicker", function () {
    $(".m_datetimepicker").datetimepicker({
        autoclose: true,
        todayBtn: true,
        keepOpen: false,
        startDate: today,
        dateFormat: 'dd/mm/yy',
    });
});

this.addForm.value 该列表示日期时间选择器值未与该值绑定 formControlName , 它给了我 null
