How to convert all html files in a folder to PDFs

Hi,

I want to convert all HTML files in a folder to PDFs using Javascript. I am aware that action wizard can be used for this. However, I do not want to run the action wizard. Rather I want a Javascript to do this.

I am very new in using Javascript. Hence an example code showing this task will be appreciated. Also please guide where the script should be placed and how to run the script.

Thanks
