Append String to Page Name when Extension Isn't Necessarily Mandatory?

What  I want to do is append "-confirmation" to the URL of a page (but using output as a string). It will always be before the file extension, if one exists? Since the extension isn't mandatory, the URL can have two different structures. Not sure how to accomplish this?

 Example (==> means returns):    ==>    ==>    ==>   ==>

Any ideas?

The above will add .html in cases where .html is not already present in URL. Please try below -

if(url.indexOf('.html') == -1) 
      url = url+ '-confirmation'; 
       url=url.replace('.html', '-confirmation.html');
