JS realizes the method of dynamically adding attributes to objects

In my work, I have to use the requirement of dynamically adding attributes to jd objects. I found a solution on the Internet. The example is as follows:

1, demo

var aa="maker";
var bb=123;
var lists={};
eval("lists."+aa+"="+bb);
eval('('+"lists."+aa+"="+bb+')');
console.log(lists);

This method has been tried and it works

2. In the project,

$("#saveform").on("click",function(){
  var param={};
  //bz订单号
  var bzorderid=$("#bzorderid").val();
  //获取所有产品
  $("#allsk .sk td input").each(function(){
   var id=this.id;
   var name=this.name;
   var val=$("#"+id).val();
   //动态添加属性、赋值
   eval("param."+name+"="+val)
  });
}

is used to traverse the input to obtain the value, and the js object dynamically adds attributes and attribute value.

I hope this article will be helpful to everyone in JavaScript programming.
