Implementing an automatic link generation feature for files within a directory using JavaScript

I could really use some assistance with this. I created a YouTube example, which can be viewed in this PLNKR LINK: http://plnkr.co/edit/44EQKSjP3Gl566wczKL6?p=preview

In my folder named embed, I have files titled p9zdCra9gCE and QrMOu4GU3uU, as shown below:

<div class="ytid" data-str="p9zdCra9gCE">video 1</div>
<div class="ytid" data-str="QrMOu4GU3uU">video 2</div>

I am wondering if there is a way to automatically display any new files like p9zdCra9gCE.html or QrMOu4GU3uU.html that are added to the embed folder on the index page. It should appear alongside other video buttons like this:

<div class="ytid" data-str="p9zdCra9gCE">video 1</div>
<div class="ytid" data-str="QrMOu4GU3uU">video 2</div>
<div class="ytid" data-str="AnotherFile">video 3</div>
<div class="ytid" data-str="AnotherFile">video 4</div>
<div class="ytid" data-str="AnotherFile">video 5</div>

Any suggestions on how to achieve this?

For a demo, you can click here. If you input something like p9zdCra9gCE.html in the embed textarea, it will be added to the video tab and play immediately. Please inform me if there are any discrepancies with your requirements. I hope this solution helps!

In order to assist you in navigating this process, I recommend the following steps:
1. Utilize a server-side language such as PHP. It has been noted that accessing the file system on the server is not feasible with JavaScript or jQuery.
2. Consider employing the scandir() method (a feature of PHP) to retrieve the contents of your designated folder. Refer to http://php.net/manual/en/function.scandir.php for more information.
3. The outcome will be an array containing all files and directories within the scanned location. Implement a foreach loop to create the ytid divs accordingly.

If these instructions seem overwhelming, I recommend seeking out tutorials on PHP through platforms like Codecademy or other online resources. Best of luck!
