Although I didn’t had any use for this, I wanted to share how you can open multiple pages with only one link.
Just use this code:
<a href=“YOUR_FIRST_LINK“ target=“_blank“ onclick=“window.open(‚YOUR_SECOND_LINK‘); window.open(‚YOUR_THIRD_LINK‘);“>This link opens 3 pages in a single click</a>
If you want to add more pages, you only have to add more window.open(‚YOUR_LINK‘); phrases.
