I’m absolutely not expert on js and html, following the answers and samples of stackoverflow I found a way to publish on my website a external html source. In the external source there are present some link to download csv files, in the original page the links works correctly in the ajax responce is not possible to download these files.
I have read many posts on a possible solution but I was unable to understand how to apply the proposed solutions.
Another problem is a DIV that I tried to remove through the .remove () instruction without success (always following some posts found).
