Opening new tab without moving to it

Question

I need to open a tab with a new URL from JSF via Javascript. The problem is that I don't know how to open it without moving to this newly opened tab. In other words, I want to open a new tab, but stay on my current page.

here is my JSF code:

<h:commandButton value="#{appRes['xyz']}" action="#{someBean.downloadFromDetails()}"
    rendered="#{someBean.isDownloadAvailableOnDetails()}" onclick="showUrl();" onblur="location.reload();"/>

and here is my Javascript code:

function showUrl() {
    window.open('http://www.stackoverflow.com');
}

Answer 1

This is my idea...

function showUrl() {
  window.open(window.location);
  window.location='http://www.stackoverflow.com';
}
