Opening url in new tab

I am trying to open a new tab with javascript.

How to write it so that it would work in chrome, firefox and IE7?

(the pages are开发者_开发问答 on the same domain)

UPD: Let's presume that the user uses the default configuration of IE7...

You cannot control how the browser will handle opening new popups / pages. This is entirely handled by the browser. If the user has set their browser up to open new pages/popups in a new window, you cannot force your own page to open in a tab.

Plain HTML:

<a href="newpage.html" target="_blank">click here</a>

Javascript:

window.open("newpage.html", "_blank");

But keep in mind what psynnott said.
