1 click open more than 1 link html

I made a page which I put all links next to each ot开发者_StackOverflow中文版her. Every link opens different website. I have to click one by one to them in order to open them and there are 20 links so it takes while everytime. Is there anybody knows how can I make it so when I click only 1 link it opens all of them ?

You can do this with JavaScript, but popup blockers and what not are going to get in the way.

You're looking for window.open().

If it were me, I'd just build an all-in-one installer with NSIS, or at least zip the installers into one ZIP file to distribute.
