Angular js convert string property to boolean inside json object

Question

i'm working with angular js and i have the following array that contains many json object , each objects has the property "isSingle" which contains "true" or "false" , my issue is how to convert this property to boolean true or false :

[
    {
      "noFolder": "AW343",
      "type": "T7",
      "creationDate": "22/05/2017",
      "isSingle": "true"
    },
    {
      "noFolder": "AW35",
      "type": "T34",
      "creationDate": "09/05/2017",
      "isSingle": "false"
    },
    {
      "noFolder": "ASW3",
      "type": "T3",
      "creationDate": "05/07/2017",
      "isSingle": "true"
    },
    {
      "noFolder": "BG5",
      "type": "T1",
      "creationDate": "22/12/2018",
      "isSingle": "false"
    }

]

my desired result is to have objects like :

  {
      "noFolder": "ASW3",
      "type": "T3",
      "creationDate": "05/07/2017",
      "isSingle": true
    }

Answer 1

通过对象的简单循环将字符串转换为bool：

yourArray.forEach(x => x.isSingle = x.isSingle === 'true');

Answer 2

Just Iterate over the array and replace the value as per your requirement like this -

var obj = [
    {
      "noFolder": "AW343",
      "type": "T7",
      "creationDate": "22/05/2017",
      "isSingle": "true"
    },
    {
      "noFolder": "AW35",
      "type": "T34",
      "creationDate": "09/05/2017",
      "isSingle": "false"
    },
    {
      "noFolder": "ASW3",
      "type": "T3",
      "creationDate": "05/07/2017",
      "isSingle": "true"
    },
    {
      "noFolder": "BG5",
      "type": "T1",
      "creationDate": "22/12/2018",
      "isSingle": "false"
    }

]

obj.map((e) => {
    e.isSingle == "true" ? e.isSingle = true : e.isSingle = false
});

Using reduce method.

let updated_array = array.reduce(function(acc, elem) {
    acc.push(Object.assign({}, elem, { isSingle: (elem['isSingle'] == true ? true : false) }));
    return acc;
}, []);
