如何根据在Angular中选择的下拉值自动填充输入字段？

<select [(ngModel)]="selectedValue">
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

<input [(ngModel)]="inputValue" [disabled]="!selectedValue" />

selectedValue: string;
inputValue: string;

// 根据选择的下拉值更新输入字段的值
updateInputValue() {
  if (this.selectedValue === 'option1') {
    this.inputValue = '填充的值1';
  } else if (this.selectedValue === 'option2') {
    this.inputValue = '填充的值2';
  } else if (this.selectedValue === 'option3') {
    this.inputValue = '填充的值3';
  }
}

<select [(ngModel)]="selectedValue" (ngModelChange)="updateInputValue()">
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

<input [(ngModel)]="inputValue" [disabled]="!selectedValue" />
