怎么替换成红色的值 对象可能有多个

Answer 1

const assessingOfficer = [
  {
    AssessingStatus: 2,
  },
  {
    AssessingStatus: 2,
  },
  {
    AssessingStatus: 1,
  },
  {
    AssessingStatus: 1,
  },
  {
    AssessingStatus: 2,
  },
  {
    AssessingStatus: 2,
  },
  {
    AssessingStatus: 2,
  },
];

var assessingOfficerArr = assessingOfficer.map((el) => el.AssessingStatus);

var deepAssessingOfficerArr = JSON.parse(JSON.stringify(assessingOfficerArr));

for (let i = 0; i < deepAssessingOfficerArr.length; i++) {
  if (i === 0)
    assessingOfficerArr[0] = deepAssessingOfficerArr[0] === 1 ? 3 : deepAssessingOfficerArr[0];
  if (i > 0)
    assessingOfficerArr[i] =
      deepAssessingOfficerArr[i] === 1
        ? 3
        : deepAssessingOfficerArr[i - 1] === 1
        ? 1
        : deepAssessingOfficerArr[i];
}

console.log('assessingOfficerArr', assessingOfficerArr);

Answer 2

就是写一个 .map() 循环一下咯。

但是不知道你的转换规则是什么，所以只能简单写一个伪代码给你看

const assessingOfficer = [...] // 你的数组数据
const newAssessingOfficer = assessingOfficer.map(item => {
    return {
        ...item,
        AssessingStatus: AssessingStatusTransfer(item.AssessingStatus)
    }
})
// 状态转换函数
function AssessingStatusTransfer(val){
    // 这里是你的转换规则
    const newVal = ....
    return newVal
}
