Assuming I have an Amazon product URL like so

http://www.amazon.com/Kindle-Wireless-Reading-Display-Generation/dp/B0015T963C/ref=amb_link_86123711_2?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-1&pf_rd_r=0AY9N5GXRYHCADJP5P0V&pf_rd_t=101&pf_rd_p=500528151&pf_rd_i=507846

How could I scrape just the ASIN using javascript?
Thanks!

Amazon's detail pages can have several forms, so to be thorough you should check for them all. These are all equivalent:

http://www.amazon.com/Kindle-Wireless-Reading-Display-Generation/dp/B0015T963C

http://www.amazon.com/dp/B0015T963C

http://www.amazon.com/gp/product/B0015T963C

http://www.amazon.com/gp/product/glance/B0015T963C

They always look like either this or this:

http://www.amazon.com/<SEO STRING>/dp/<VIEW>/ASIN

http://www.amazon.com/gp/product/<VIEW>/ASIN

This should do it:

var url = http://www.amazon.com/Kindle-Wireless-Reading-Display-Generation/dp/B0015T963C;

var regex = RegExp(http://www.amazon.com/([\w-]+/)?(dp|gp/product)/(\w+/)?(\w{10}));

m = url.match(regex);

if (m) { 

    alert(ASIN= + m[4]);

}
