How to restrict paste function after the maxlength

I have got a task to restrict paste function when it comes to maximum. For that I used the code 

 $(document).on('keyup', '.txtStyle', function (e) {
                debugger;
                var charsSoFar = $('#' + container_id).val().length;
                remaining = 500 - charsSoFar;
                $('#rem_' + container_id).text('Characters remaining ' + remaining);
                if (charsSoFar > 500) {
                    alert("Hai");
                }
            });

How can I restrict the Paste function? Please help

As my understanding you want to stop user input once its reach max, so i suggest 

if (textbox.val().length >500 ) 
   textbox.val(textbox.val().substring(0,500));

It will give illusion that after 500 char user can't input or paste in textbox.

    remaining = 500 - charsSoFar;
    $('#rem_' + container_id).text('Characters remaining ' + remaining);
    if (charsSoFar > 500) {
        if (e.keyCode == 86 && e.ctrlKey) {
            alert("Hai");
        }
    }
});

Take look on this..... This will help you.

if (event.ctrlKey==true && (event.which == '118' || event.which == '86')) {
   alert('Paste Restricted!');
   e.preventDefault();
}
