I need to select two fields out of three fields from Json data using Linq.js

Required output should be 

[{ "A": -27, C: "country 1" } , { "A": 28 , C: "country 2"} ]

using "linq.js" from following path: [ https://raw.github.com/gist/1175460/fb7404d46cab20e31601740ab8b35d99a584f941/linq.js ]

Sample data

var Data = [{ "A": -27, "B": -39, C: "country 1" }, { "A": 28, "B": 0 , C: "country 2"}]

var filter = "  x =>    x['A'], x['C']  ";
var findItem = Enumerable.From(Data)
.Select(filter)
.ToArray();

console.log(findItem);

Solution

  • Your "lambda" function must return a valid java object.

    Your query should be more like this:

    var query = Enumerable.From(data)
    .Select("x => { A: x['A'], X: x['C'] }") // object initializer
    .ToArray();
