Javascript + Chrome Developer Tools Expert Needed

Hi, I need a client side script that saves html data into a local storage object that I can save locally. The script will do the following tasks - 1. Click on a link 2. Save all html (if possible, all images as well) into local storage object 3. Run on a loop and download file. For example, on [login to view URL] (logged in). We go to see all employees, we click next page, save that page, click next page, save that page, etc. Finally, after 15, 20 pages, download all locally.
