How do I open Javascript link in new tab?

How do you open a new tab by clicking a button using javascript?

• Ok, so I'm abit new to javascript and I'm trying to use javascript on my website I'm making. Basically, I want the script to be able to open up a new tab to a different link, i.e facebook.com. But i want the javascript to only run when I click on say a "Go here" button. How would I do that? I've gone through google, but again, i'm new to javascript and have no idea what i'm to change in any of the scripting. So any help would be appreciated greatly.

• Answer:

  Why do you need javascript for this? You can just use formtarget (if using a form button) or target (if using an anchor tag) that is pointed to _new or _blank. If you must use javascript, do: onclick="javascript:window.open('someth… here')" and use whatever url you need instead.
