在Angular中修改json

import { HttpClient } from '@angular/common/http';

export class MyComponent {
  jsonData: any;

  constructor(private http: HttpClient) {
    this.http.get('path/to/json/file.json').subscribe(data => {
      this.jsonData = data;
    });
  }
}

// 修改JSON对象的属性值
this.jsonData.property = 'new value';

// 修改嵌套JSON对象的属性值
this.jsonData.nestedObject.property = 'new value';

// 修改JSON数组中的元素
this.jsonData.array[0] = 'new value';

this.http.put('path/to/save/json', this.jsonData).subscribe(response => {
  console.log('JSON data saved successfully');
});
