1. 数组是在页面定义,不是从api获取:

const arrayData= [{index: 0,is_required: true,name: "vmvdnksl",type: "LONG_TEXT"},{index: 1,is_required: true,name: "dsvnlk",type: "MULTIPLE_SELECTORS"}];

const result = arrayData.map(({type,index,...rest}) => ({...rest}));

console.log(result);

2. 数组格式未知,是从api获取的数据

var arrayData = {
  0: {
       index: 0,
       is_required: true,
       name: "vmvdnksl",
       type: "LONG_TEXT"
     },
  1: {
       index: 1,
       is_required: true,
       name: "dsvnlk",
       type: "MULTIPLE_SELECTORS"
     }
  };
  
  
for (let key in arrayData) {
  delete arrayData[key].index;
  delete arrayData[key].type;
}
  
console.log(arrayData);
