Extracting the Item ID from an eBay url using javascript

I need to extract -- using Javascript -- the Item ID value from an ebay URL that has the following format:

http://cgi.ebay.com/VINTAGE-PRESSED-GLASS-RUBY-FLASHED-DIAMOND-CANDY-DISH_W0QQitemZ120589354693QQcategoryZ4764QQcmdZViewItemQQ_trksidZp3907.m263QQ_trkparmsZalgo%3DSIC%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%252BDDSIC%26otn%3D8%26pmod%3D370178498217%26po%3DLVI%26ps%3D63%26clkid%3D7427724710710527929

(The item ID value is boldfaced in the url above)

How would I write a regular expression to extract that value and assign it to a variable?

I have the following, but it doesn't seem to be working:

itemid = ebayUrl.replace(/QQitemZ(\d+?)QQ/, '$1');

Please advise.

Thanks!

Looks pretty close - remove the question mark.

I've removed the question mark, but it still isn't working.

For example, .. if you run the following javascript, .. you'll see that it returns the entire url instead of the extracted Item ID value:

<script language="JavaScript">
      var ebayUrl = "http://cgi.ebay.com/VINTAGE-PRESSED-GLASS-RUBY-FLASHED-DIAMOND-CANDY-DISH_W0QQitemZ120589354693QQcategoryZ4764QQcmdZViewItemQQ_trksidZp3907.m263QQ_trkparmsZalgo%3DSIC%26itu%3DUCI%252BIA%252BUA%252BFICS%252BUFI%252BDDSIC%26otn%3D8%26pmod%3D370178498217%26po%3DLVI%26ps%3D63%26clkid%3D7427724710710527929";
      itemid = ebayUrl.replace("/QQitemZ(\d+?)QQ/", "$1");
      alert(itemid);
</script>

Any takers?

Thank you both. Both of these suggestions worked equally well for me.
