Change href file but not query string with jQuery

Question

I'd like users with JavaScript enabled to see page results.php. Users with JavaScript disabled should see results_d.php.

To do this I'm initially displaying my links with results_d.php. Then by using JavaScript to change the destination in the links, only the users with JavaScript enabled will see the rich content.

There are a few questions on here about using jQuery to change the whole href destination, but how can I just change the file name and keep the query string as it is?

I was thinking something like this, but it's not working...

$(document).ready(function()
{
    $('a').attr('href').replace('results_d', 'results');
});

Answer 1

$(document).ready(function() { 
    $('a').attr('href', function(index, href) {
        return 'results?'+(href.split('?')[1])
    });
});

Answer 2

$(document).ready(function() { 
  $('a').each(function() {
    $(this).attr('href',$(this).attr('href').replace('results_d', 'results'));
  });
});

Answer 3

Thanks for the replied guys. I got a few errors with that logic though in my file. I've added my errors to the comments.

In the end, what did work for me was:

$('a').each(function()
{ 
    this.href = this.href.replace('results_d', 'results');
});
