Question

我已经以angular6 / 7的反应形式实现了日期时间选择器。而且，我什至避免对该数据时间选择器应用表单控件。我的是angular2 datetimepicker-从'angular2-datetimepicker'导入{AngularDateTimePickerModule};

但是，我遇到错误-

   ERROR TypeError: Cannot read property 'getMonth' of undefined

请帮助解决该错误。


<form (ngSubmit) = "addTask(addTaskForm.value)" [formGroup] = "addTaskForm">

                    <div class= "form-group">
                      <label>Task Id : </label>
                      <input type= "text" maxlength = "100" class= "form-control" placeholder = "Enter Task Id " 
                      [formControl] = "addTaskForm.controls['addTaskId']" required>
                      <p style = "color:red" *ngIf= "addTaskForm.get('addTaskId').hasError('required')">*TaskId is required</p>

谢谢。我解决了查询。

app.component.ts-

date: Date = new Date();
  settings = {
    bigBanner: true,
    timePicker: true,
    format: 'dd-MM-yyyy hh:mm',
    defaultOpen: false,
    closeOnSelect: true
  }


 constructor(private fb: FormBuilder) {

    this.addTaskForm = this.fb.group({

      'addTaskId': new FormControl ('',[ Validators.required]),
      'addTaskName':new FormControl ( '', [Validators.required, Validators.pattern("[A-Za-z0-9 @)(_-]{1,2500}")]),
      'addDescriptionName':new FormControl (  ['', Validators.required, Validators.pattern("[A-Za-z0-9 @)(_-]{1,2500}")]),

      'date': new Date(),

      'addStatusName':new FormControl ( '',[ Validators.required, Validators.pattern("[A-Za-z0-9 @)(_-]{1,2500}")])

app.component.html

<div class= "form-group">



                            <label>Start Date-Time : </label>

                            <angular2-date-picker (onDateSelect)="onDateSelect($event)"  [formControl] = "addTaskForm.controls['date']" [settings]="settings"  required></angular2-date-picker>


                          </div>

    })
  }
