How to convert array of objects into array of arrays

Question

The array of objects looks like this:

[
    {\"Number\":64,\"Earning\":160000},{\"Number\":64,\"Earning\":160000},
    {\"Number\":64,\"Earning\":160000},{\"         


        

Answer 1

Iterate over the array and construct a new array. Most javascript libraries have a map function where you only need to supply a mapping function to achieve this.

Answer 2

This Way (Works only in modern browsers):

var a = [
    {"Number":64,"Earning":160000},{"Number":64,"Earning":160000},
    {"Number":64,"Earning":160000},{"Number":64,"Earning":160000},
    {"Number":64,"Earning":160000},{"Number":64,"Earning":160000},
    {"Number":64,"Earning":160000},{"Number":64,"Earning":160000}
];

var b = a.map(function(i) {  return [i.Earning,i.Number];  });   // New Array

Answer 3

If you're using this exact structure, you can do something like this. Where inputData is the first JSON structure, and outputData will be the data outputted.

var outputData = [];

for(var i = 0; i < inputData.length; i++) {
    var input = inputData[i];

    outputData.push([input.Earning, input.Number]);
}
