Get Current User name using JQuery in sharepoint 2013

Here is the code to fetch current user name ( logged in user name ) using Jquery , this can be user on content editor webpart or list form .

things to take care before u use below code
1. download jquery-1.4.2.min.js and jquery.SPServices-0.5.7.min.js and
2. upload both the downloaded files to style library under new folder named as js.


<script language="javascript" src="../../Style Library//js/jquery-1.4.2.min.js" type="text/javascript"></script>  
<script language="javascript" src="../../Style Library/js/jquery.SPServices-0.5.7.min.js" type="text/javascript"></script>
<script type="text/javascript">
 
//to make sure above added script links are loaded on page
  $(document).ready(function() {
 
// to get formlabel control
  if (document.getElementById("formlabel") != null)
{

document.getElementById("formlabel").innerText =  $().SPServices.SPGetCurrentUser(
{fieldName:"Title",
debug:false
});
}
</script>

formlabel is html label , innertext of label is set to current logged in user name programmatically using above code.
