Well, I am not talented in Javascript and realised I can't do this in an HTML making software like Dreamweaver that I like a lot. Actually there is the possibility to do Javascript in Dreamweaver but I can't porgram it. I saw an example somewhere here in one of the forums but can't figure it out:
<a id='threelinks' href='#'>Open three tabs</a>
then use jQuery (or Javascript )
$("a#threelinks").on('click', function() {
window.open('page1.php', 'first page');
window.open('page2.php', 'secondpage');
window.open('page3.php', 'third page');
return false; });
Here, I don't understand what eg. 'page1.php' means either 'first page'. I guess, page1.php could mean the html page that I want to load but that php disturbes me. And 'first page' would mean the target? I am pretty sure that I am totally wrong. I am sorry that I am this silly.
To answer your question, Javascript would suit me the best.
