JSON

Overview

JSON means JavaScript Object Notation. Kinx Object is just a JSON object and you can use it easily.

Parsing JSON

Kinx provides a utility function of JSON.parse(). You can use it to parse a JSON string and construct an actual Kinx Object.

Here is an example.

var x = JSON.parse(%{
    {
        "aaa": 10,
        "bbb": 20
    }
});
System.println(x);  // => {"aaa":10,"bbb":20}

JSON.parse() can also handle the key without quotation.

var x = JSON.parse(%{
    {
        aaa: 10,
        bbb: 20
    }
});
System.println(x);  // => {"aaa":10,"bbb":20}

Stringify

You can use JSON.stringify() to make it stringify from a JSON object, and also you can apply toJsonString() to an object directly.

var x = {
    aaa: 10,
    bbb: 20
};
System.println(JSON.stringify(x)); // => {"aaa":10,"bbb":20}

The second parameter of JSON.stringify() is a flag and it is true if using indentation.

var x = {
    aaa: 10,
    bbb: 20
};
System.println(JSON.stringify(x, true));
// {
//     "aaa": 10,
//     "bbb": 20
// }

Here is the toJsonString version.

var x = {
    aaa: 10,
    bbb: 20
};
System.println(x.toJsonString(true));
// {
//     "aaa": 10,
//     "bbb": 20
// }

Examples

Example 1. Parsing JSON

Code

var x = JSON.parse(%{
    {
        aaa: 10,
        bbb: 20
    }
});
System.println(x);

Result

{"aaa":10,"bbb":20}

Example 2. JSON.stringify

Code

var x = {
    aaa: 10,
    bbb: 20
};
System.println(JSON.stringify(x));

Result

{"aaa":10,"bbb":20}

Example 1. toJsonString

Code

var x = {
    aaa: 10,
    bbb: 20
};
System.println(x.toJsonString(true));

Result

{
    "aaa": 10,
    "bbb": 20
}
