title: extract vimeo video id from the url
body: <p>Though this question is available on SO, I am facing a little problem.I failed to extract the vimeo id using vimeo regex used here: <a href="http://jsbin.com/asuqic/184/edit?js,output" rel="nofollow">Vimeo Regex</a></p>
  
  <h2>My codes I,m using now:</h2>
  
  <pre><code>function vimeoProcess(url){
     var vimeoReg = /https?:\/\/(?:www\.)?vimeo.com\/(?:channels\/(?:\w+\/)?|groups\/([^\/]*)\/videos\/|album\/(\d+)\/video\/|)(\d+)(?:$|\/|\?)/;
     var match = url.match(vimeoReg);
     if (match){
        console.log(match[3]);
     }else{
        return "&lt;span class='error'&gt;error&lt;/span&gt;";
     }
  }
  </code></pre>
  
  <p>It does not consoles any thing.
  Can any one help?</p>
