change input values randomly

Question

I have 3 text inputs, and also have one hidden input with some numbers as its value: <input type="hidden" name="" value="100,101,105,106,109,2">. Now I'd like to do this - when you click on 'Go' button it will randomly show one of those numbers as input values so all inputs will have value after clicking Go button. How can I do this ?

**1** array of numbers **2** setInterval **3.** Random number generation in bounds of array.length **4.** Update value of textbox. — Tushar, Oct 15 '15 at 11:42

@Sherali Turdiyev it is a bit like to what I want. Just now with your code same value can appear twice in 2 or 3 input fields, can we fix this ? — aiddev, Oct 15 '15 at 11:48

Just use following code: Demo

$("#goBtn").click(function () {
    var arr = $("#values").val().split(",");
    var random = arr.splice(parseInt(Math.random()*arr.length), 1)[0];
    $("#num1").val(random);

     random = arr.splice(parseInt(Math.random()*arr.length), 1)[0];
    $("#num2").val(random);

     random = arr.splice(parseInt(Math.random()*arr.length), 1)[0];
    $("#num3").val(random);

    return false;
});
