title: Simple jQuery / javascript method to escape special characters in string for regexp
body: <p>I'm performing a regular expression using the match() method on a string that comes from the user and could contain anything, including $^'s etc.. so I need to escape those characters before this happens.</p>
  
  <p>Is there a common function in jQuery to do this, a well known javascript function or am I going to have to do it manually (with the chance I might miss something?)</p>
