Although your questions is very poorly written, I believe it is more important that you get the answer you're looking for.

Do the following:

1. Add event listener to the window/document(in your case, keydown)
2. Get the ascii code of backspace(0x08 or 8 in decimal)
3. Prevent the default functionality of keydown
4. Refresh the page if it is backspace

Here it is in code.

window.addEventListener('keydown', function(e)
{
    if( e.keyCode == '8' )
    {
        e.preventDefault();  // prevent backspace from going to browser
                          // history
        // add reload code
        location.reload();
    }
}, false);
