我在项目中使用ngx bootstrap datepicker

仅需要像上面的图像一样选择月份和年份

<input type="text"
         class="form-control"
          (bsValueChange)="modelChanged($event)"
          #dp="bsDatepicker"
          bsDatepicker [(bsValue)]="bsValue"
          [bsConfig]="{ dateInputFormat: 'YYYY-MM-DD' }"
          >

有没有办法像这样配置日期选择器？或建议任何允许此功能的替代日期选择器

我试图以角度2上传图像,我没有列出错误但是文件添加的位置没有变化详细代码在下面给出

**.ts**
............
  onFileChange(event) {
    if(event.target.files.length > 0) {
      let file = event.target.files[0];
      this.fileName = file.name;
      this.imageUpload['upload'] = this.fileName;
      this.form.get('upload').setValue(file);
      console.log(file);
      console.log('filename',this.fileName);


    }
  }

 private prepareSave(): any {
    let inputVal = new FormData();
    inputVal.append('upload', this.form.get('upload').value,this.imageUpload['upload']);
    console.log(inputVal);
    return inputVal;
  }

  onSubmit() {
    this.imageUpload['upload'] = this.fileName;
    const formModel = this.prepareSave();
    this.loading = true;

    var body = formModel;
    let url = this.ImageUploadURL;
    let headers = new Headers({ 'Content-Type': 'multipart/form-data' ,'Authorization': 'Bearer ' + this.accountsService.accessToken });
    let options = new RequestOptions({ headers: headers }); …
