How to move script from view to application.js in rails

Question

Doing some research this is the code that worked for me but it is in the view and I would like to move to the application.js so I can use in different forms.

The other thing is that I have two scripts doing the same thing. One is for when I click on the checkbox and the other is to check if it is already checked when loading the page. Can I merge them so I don't have to repeat the code?

<script type="text/javascript">
    function hideAddress()
    {
        if($('#same').is(":checked"))
            $("#mailing-address").hide();
        else
            $("#mailing-address").show();
    }
</script>
<script type="text/javascript">
    $( document ).ready(function hideAddress() {
        {
            if ($('#same').is(":checked"))
                $("#mailing-address").hide();
            else
                $("#mailing-address").show();
        }
    });
</script>

Edit

I tried moving to the application.js without the script tags, but now the .ready function doesn't work unless I reload the page.

$( document ).ready(hideAddress);


    function hideAddress()
    {
        if($('#same').is(":checked"))
            $("#mailing-address").hide();
        else
            $("#mailing-address").show();
    }

So it looks like turbolinks makes document ready not work properly, so instead of (document).ready I had to do $(document).on('turbolinks:load' .

So i ended up setting this code on my application.js

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .


    $(document).on('turbolinks:load', hideAddress );

    function hideAddress()
    {
        if($('#same').is(":checked"))
            $("#mailing-address").hide();
        else
            $("#mailing-address").show();
    }
