How do you make an external link to a third party website to pop-up in small window?

[luckystrike]

I'm still quite a newbie and really need this function - how can i make a link to a third party website to pop-up in a new small window using html? - as opposed a user clicking on it and taking the place of my site's page thus losing traffic..

any help to a newbie would be appreciated :)

Andy - new webmaster at financial-spread-betting.com - and any tips on how I could improve the website given my limited abilities are welcome too :)

In HTML (requires a transitional doctype):

<a href="http://www.w3.org/" target="_blank">W3C</a>

In JavaScript:

<a href="http://www.w3.org/" onclick="window.open(this.href); return false;">W3C</a> and see http://www.webdevfaqs.com/javascript.php#popup for more info

Note that you should not be using popups on an accessible website. From the Web Content Accessibility Guidelines:

10.1 Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the user.

You can use pop-ups on an accessible website but the idea is you inform the use either via plaintext or the title attribute like I do within this directory: http://www.xhtmlcoder.com/worthvalley/

What you shouldn't do is make auto-loading pop-ups or prevent the user from accessing the page if JavaScript is disabled.
