Open extendSearch link in New Window

[rcshield]

How can I get the hyperlink below to open in a new window? Target="_blank" does not work.

<script type="text/javascript">
function extendSearch(addon) {
window.location.search += addon;
}
</script>
...
<a href="#" onclick="extendSearch('&page=2');return false">

Try

function extendSearch(addon) {
window.open(window.location.href + addon, '_blank' );
}

Thanks for your help. When I tried the suggestion, the new window opened to the following address:

http://www.example.com/&print=true

How can I get the new window to open to the address below?

http://www.example.com/?&print=true

You'd want to first check to see if there is a ? in the current location URL. If not, then append one on, if so, then append '&' instead.

function extendSearch(addon) {
  if (window.location.href.indexof('?') == -1) {
    // Append ?
    addon = '?' + addon;
  }
  else {
    // Append &
    addon = '&' + addon;
  }
  window.open(window.location.href + addon, '_blank'); 
}

Or the more condensed form:

function extendSearch(addon) {
  window.open(window.location.href + (window.location.href.indexOf('?') == -1 ? '?' : '&') + addon, '_blank'); 
}

And make sure your links don't include the &.

<a href="#" onclick="extendSearch('page=2');return false">

(Though it's important to note that this link will not work for any visitor, including search engines, that have JavaScript disabled)

Thank you, Fotiman! The "condensed" version of your Javascript code worked for me!
