[Javascript]filter for extension (.pdf)

Hello , all this is my first time here so if i made some mistake forgive me :)

What I am trying to do here is the following:
I want with javascript to get all .pdf filename + extension and make a link to them in my webpage.
I made this to filter and find the file :

Code:

---

write("The contents of " + getCurrentFolder());

fileName = findFirstFile("*.pdf*"); // Find the first file matching the filter
while(fileName.length)
{
    write(fileName);
    fileName = findNextFile();  // Find the next file matching the filter
}

---

But how to post a link to them in my webpage ?
