JsPdf page break not working

问题

I have this very simple code that works with jspdf and html2pdf but for some reason jspdf is not breaking the elements into new pages.

Any help would be appreciated

回答1:

JsPDF uses a special HTML tag...

<!--ADD_PAGE-->

...to force a page-break.
Please note that this only applies if using the addHTML method.
I had this exact problem and throwing in the tag worked perfectly.
