Given a string, how to determine if it's an IMDB id?

For the regex experts out there, I need to determine whether a given string is a properly formatted IMDB Id.

Need to do this in either ColdFusion or JavaScript. ColdFusion would look like: REFind(regex, "tt32423"), and JavaScript would look like regex.test('tt32432'), if we can get the value of regex.

Based on the discussion tab of the page you linked to, you can use this RegEx in JavaScript: /ev\d{7}\/\d{4}(-\d)?|(ch|co|ev|nm|tt)\d{7}/

example:

/ev\d{7}\/\d{4}(-\d)?|(ch|co|ev|nm|tt)\d{7}/.test("tt2964642")

Even though the ID you provided in your example fails this test, when entered as a route parameter to http://imdb.com/title/tt32423 in my browser, i'm redirected to http://imdb.com/title/tt0032423. Given that, depending on how you'll use this, you could adjust the regex to included 1 to 7 digits instead

{7} becomes {1,7}

Up to you.
