How I call a function like this in Javascript/jquery?

It show you just how much a clue I have about javascript, I'm not actually sure if this is vanilla or jquery?

Anyway the code I have is

JavaScript:

  $(document).on('ready',prepare() {
    $(document).on('change',prepare() {

    })

    function prepare {
        const checkbox = document.querySelector('input[name="timescale_radio_buttons"]:checked').value;
        document.getElementById('output-2').innerHTML = "Time: " + checkbox;
        }

    })

I need the function to run on ready, and then when there is a change, can anyone tell me how I do that here?


Cheers

Click to expand...

 $(document).on('ready',function() {
        prepare();
    $("#24Hours").on('click',function() {
        prepare();
    });
    
    $("#3Days").on('click',function() {
        prepare();
    });
                                        
});
