Extract part of current url to use in javascript function
<p>hoping someone who knows a bit about javascript maybe able to help me. I need to extract part of the url of my pagepage to use in a javascript function and append to a url. ( it's for a power reviews setup.) the portion i need to extract is the number of the example below ie. www.mydomain.com/my-product-could-be-i950.html -- so would just need the 950 part.. the number part could be 2,3,4 characters. I then need to append this to the url www.mydomain.com/write-a-review.html?pr_page_id=950 </p>

<p>could anyone help, it's a bit beyond me this one to be honest..</p>

<p>Many thanks.. Nathan</p>
