Link opens twice the same window

Question

I have next html code, to open a link into a new window:

<a rel="nueva_ventana" href="http://www.google.es">
</a>

When I click on it, it opens the same page twice, in two new windows.. which could be the problem?(I just want it to open once) Thanks!

Answer 1

Sorry, problem solved, I was importing twice my commons.js, where I was executing the rel="nueva_ventana"... so that it opened twice, thank you all!
