如何将一种 object 格式转换为另一种 object 格式

Question

This is the data I am receiving from the database based on the input values by the user. Like REX,JC2.

Main Data = [
  { 'SerNoPfx1': 'REX', 'SerNoPfx2': 'REX', 'Percentage': 100 },
  { 'SerNoPfx1': 'JC2', 'SerNoPfx2': 'JC2', 'Percentage': 100 },
  { 'SerNoPfx1': 'JC2', 'SerNoPfx2': 'REX', 'Percentage': 52.93 },
  { 'SerNoPfx1': 'REX', 'SerNoPfx2': 'JC2', 'Percentage': 52.93 },
];

needs to be converted to

data = [
  { "REX": "100", "JC2": "52" }, 
  { "REX": "0", "JC2": "100" },
];

{ 'SerNoPfx1': 'JC2', 'SerNoPfx2': 'REX', 'Percentage': 52.93 },{ 'SerNoPfx1': 'REX', 'SerNoPfx2': 'JC2', 'Percentage': 52.93 },

I have to take only one line because this is the matching percentage of REX and JC2.

REX,JC2 are the input values by the user. It is always dynamic. I need to convert this using JavaScript.

It looks like you want to get a filtered subset of the original array of objects. I. e. the objects matching both given strings in their SerNoPfx1 and SerNoPfx2 properties (regardless of the order).

 const data = [ { 'SerNoPfx1': 'REX', 'SerNoPfx2': 'REX', 'Percentage': 100 }, { 'SerNoPfx1': 'JC2', 'SerNoPfx2': 'JC2', 'Percentage': 100 }, { 'SerNoPfx1': 'JC2', 'SerNoPfx2': 'REX', 'Percentage': 52.93 }, { 'SerNoPfx1': 'REX', 'SerNoPfx2': 'JC2', 'Percentage': 52.93 } ]; const str="REX,JC2"; const fltStr=str.split(",").sort().join(","); const res=data.filter(d=>[d.SerNoPfx1,d.SerNoPfx2].sort().join(",")===fltStr); console.log(res);
