Download documents in a zip from a page using in SharePoint online

Question

I have created a product page in SharePoint Online Pages Library. It has some standard field, e-g Title and Comments. It also has a Content Query WebPart that displays a list of linked files stored in a document library, Pages library and Documents library have lookup column relation.

I want to have a download button on the page to download all linked files in a zip.

I am looking for JSOM/JavaScript solution but I can also consider sandbox solution.

First create array of file URL you want to archive. Next for each file read the byte array. Then use jzip library to create zip file in client side.
