vue通过单项值拿到树形数据的整条值

 let niu = [];
    for (let i = 0; i < afted.value.length; i++) {
      niu.push(afted.value[i].children);
    }
    newGrade.value = niu;
    console.log(newGrade.value);
  });

 let money = [];
  for (let i = 0; i < newGrade.value.length; i++) {
    for (let u = 0; u < newGrade.value[i].length; u++) {
      if (form.grade == newGrade.value[i][u].id) {
        money.push(newGrade.value[i][u]);
      }
    }
  }
