无论如何要改变这个:

<div>Some text here</div>

至:

<tr>Some text here</tr>

动态地将标签DIV标签更改为TR标签？基本上替换标签？

我有一个这样的表单组:

 this.form = fb.group({
  'teacher': [''],
  'schools': fb.array([
      fb.group({
        'school_name': [''],
        'school_description': [''],
        'events': fb.array([
          fb.group({
            'event_name': ['']
          })
        ])
      })
  ])
});
const control = (<FormArray>this.form.controls['schools']).controls[0]['events'];

如何获得嵌套数组控件'事件'？

const control = (<FormArray>this.form.controls['schools']).controls[0]['events'];
