title: Searching for '\' using javascript
body: <p>I have written  a following code to get just the file name without extension and path.I m running it in browser. </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
  var str=new String("C:\Documents and Settings\prajakta\Desktop\substr.html");
  document.write(str);
  var beg=str.lastIndexOf("\");// **HERE IS THE PROBLEM IT DOESNT GIVE ME THE INDEX OF '\'**
   alert(beg);
  var end=str.lastIndexOf (".");
   alert(end);
  document.write("&lt;br&gt;"+str.slice(beg+1,end));
