如何获取FormBuilder angular的值并与属性NgStyle一起使用

import { FormBuilder, FormGroup } from '@angular/forms';

export class YourComponent {
  form: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.form = this.formBuilder.group({
      // 在这里定义表单控件
    });
  }
}

<form [formGroup]="form">
  <input type="text" formControlName="yourControlName" [ngStyle]="yourStyleObject">
</form>

export class YourComponent {
  form: FormGroup;
  yourStyleObject: any;

  constructor(private formBuilder: FormBuilder) {
    this.form = this.formBuilder.group({
      yourControlName: [''] // 在这里定义表单控件
    });
  }

  getFormValue() {
    const value = this.form.get('yourControlName').value;
    // 在这里处理获取到的表单值

    // 可以根据表单值来设置NgStyle属性
    this.yourStyleObject = {
      'background-color': value === 'someValue' ? 'red' : 'blue'
    };
  }
}
