title: Javascript: How compare strings on alphabetical characters only?
body: <p>I'm currently rewriting the userlist implementation in an IM client interface that uses JavaScript. The names in this list are currently sorted alphabetically, and I want to edit this so that it only takes alphabetical characters in account when comparing strings.</p>
  
  <p>For instance: "1foo" comes <em>after</em> "bar", because "foo" comes after "bar".</p>
  
  <p>I know I could just create two temporary strings by removing all non-alphabetical characters from the two original strings, but I'm guessing that there must be easier ways to do this.</p>
