Convert json string value to number

Question

I have a JSON string that reads:

[{
    \"id\": \"id2\",
    \"index\": \"2\",
    \"str\": \"str2\",
    \"cent\": \"200\",
    \"triplet\": \"222\"
},
{
           


        

Answer 1

You don't need to check if the value is a number:

var temp = [{
  "id": "id2",
  "index": "2",
  "str": "str2",
  "cent": "200",
  "triplet": "222"
}, {
  "id": "id3",
  "index": "3",
  "str": "str3",
  "cent": "300",
  "triplet": "333"
}, {
  "id": "id4",
  "index": "4",
  "str": "str4",
  "cent": "400",
  "triplet": "444"
}, {
  "id": "id5",
  "index": "5",
  "str": "str5",
  "cent": "500",
  "triplet": "555"
}];

var jsonForChart = jQuery.extend(true, {}, temp);
$.each(temp, function(key, value) {
  $.each(value, function(k, v) {
    // if the value can be parsed to int, it will be OR the value remains untouched
    jsonForChart[key][k] = +v || jsonForChart[key][k];
  });
});

document.write("
" + JSON.stringify(jsonForChart, null, 3) + "
");

You get one big object but it's what you expect seeing the line var jsonForChart = jQuery.extend(true, {}, temp);.
