如何组合两个文本超链接

Let say we've the following hyper link code

<a id="cont" href="www.first_site.com">Something</a>

and i'd like to combine it with pop up using the following java code

<script language="javascript">
var popupWindow = null;
function centeredPopup(url,winName,w,h,scroll){
LeftPosition = (screen.width) ? (screen.width-w)/2 : 0;
TopPosition = (screen.height) ? (screen.height-h)/2 : 0;
settings =
'height='+h+',width='+w+',top='+TopPosition+',left='+LeftPosition+',scrollbars='+scroll+',resizable'
popupWindow = window.open(url,winName,settings)
}
</script>

<a href="www.second_site.com" onclick="centeredPopup(this.href,'myWindow','500','300','yes');return false">Anything</a>

Is there any idea i can combine both so that when i click on Something at 1st hyper link , it open up the pop up of www.second_site.com and moves to www.first_site.com

any help ~ thanks

If I didn't misunderstand you…

<a href="http://www.first_site.com" onclick="centeredPopup(this.href,'myWindow','500','300','yes'); window.location='http://www.second_site.com'; return false">Anything</a>

Note that if you don't make it return false, it opens the same site the popup window opens.

EDIT: Sorry for confusing the site order. Here's the correct version:

<a href="http://www.second_site.com" onclick="centeredPopup(this.href,'myWindow','500','300','yes'); window.location='http://www.first_site.com'; return false">Anything</a>

If you use the same window name, both calls to window.open will open the url in the same window/tab. The variable popupWindow won't help much in your case, because the access to most of the referenced window's properties will be denied due to the same-origin-policy.
