在对象的嵌套数组angular2中搜索值

function searchValue(obj: any, value: any): boolean {
  if (Array.isArray(obj)) {
    for (let i = 0; i < obj.length; i++) {
      if (searchValue(obj[i], value)) {
        return true;
      }
    }
  } else if (typeof obj === 'object') {
    for (let key in obj) {
      if (searchValue(obj[key], value)) {
        return true;
      }
    }
  } else if (obj === value) {
    return true;
  }
  
  return false;
}
