How to shuffle JSON.parse data?

February 16, 2023

Is it possible to shuffle a json parsed result from ajax?

$.ajax({
    method: 'GET',
    url: '/-pathSomething-/--ExampleOnly--',
    data: { sample: sample, sample: sample, sample: sample },
    success: function (result) {
        var ExamDislayQNChoiceML = JSON.parse(result);
    }
});

it is looks like this

i don’t know how to do it so i don’t have much code to show..

expected output.
randomly

{ QuesNo: 3, QuesID: 3, ... }
{ QuesNo: 1, QuesID: 1, ... }
{ QuesNo: 4, QuesID: 4, ... }
{ QuesNo: 2, QuesID: 2, ... }
{ QuesNo: 5, QuesID: 5, ... }

>Solution :

use the Fisher-Yates shuffle algorithm here is a documentation link: https://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle and Here’s an example of how use it to shuffle the array of objects

$.ajax({
    method: 'GET',
    url: '/-pathSomething-/--ExampleOnly--',
    data: { sample: sample, sample: sample, sample: sample },
    success: function (result) {
        var ExamDislayQNChoiceML = JSON.parse(result);
        shuffleArray(ExamDislayQNChoiceML);
        console.log(ExamDislayQNChoiceML); // shuffled array
    }
});

function shuffleArray(array) {
    for (let i = array.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [array[i], array[j]] = [array[j], array[i]];
    }
}
