NodeJ如何在对象中创建动态值

Question

我希望它能够动态变化多次。 我该怎么办？？

wherequery = {
  [columnname[1]] : {
      [Op.like]: '%'+columnvalue[1] +'%'
    },
    [columnname[2]] : {
      [Op.like]: '%'+columnvalue[2] +'%'
    },
    [columnname[3]] : {
      [Op.like]: '%'+columnvalue[3] +'%'
    }
};

exports.searchAll = (req,res,next) =>{

 var columnname =  Object.keys(req.body);
 var columnvalue =  Object.values(req.body);

// var count = Object.keys(req.body).length;

var wherequery =[];

console.log(req.body);
// console.log(wherequery);
var includeRelation=[];
    if (req.body.tableName =='applications' || req.body.tableName =='producers' || req.body.tableName == 'recyclers' ){

      //For Closed Producers
if (columnname.includes('producerId')){
  console.log("In closed producer");
  wherequery = {
    status: 1, [columnname[4]]:[columnvalue[4]] ,
    [columnname[1]] : {
      [Op.like]: '%'+columnvalue[1] +'%'
    },
    [columnname[2]] : {
      [Op.like]: '%'+columnvalue[2] +'%'
    },'$recycler.name$':{
          [Op.like]: '%'+columnvalue[3]+'%'
        }
      }
     includeRelation =   [{
        model: db.producers,
        required: true,
        as: 'producer',
        all: true

    ]
}


if (!columnname.includes('producerId')){

      // }
      console.log("ProducerNamee:after if:::" + req.body.columnname);

    let pageSize = 10;
