title: Regular expression match !
body: <p>I am trying to find for the string of the format <strong>abc1234</strong>. I can compare character taking at each index whether is alpha or numeric and get the result. Instead wrote for a pattern match but couldn't succeed. Could some one know me where I am going wrong ?</p>
  
  <pre><code>var clid = "mxv4013" ;
  if(clid.match("/[a-z]{3}(?=[0-9]{4})/i") != null){
      alert("success") ;
  }
  </code></pre>
  
  <p>Thanks.</p>
