<button type="button" onclick='showData()'>Edit</button>
<script type="text/javascript">
			function showData()
			{
			if (window.XMLHttpRequest)
			  {// code for IE7+, Firefox, Chrome, Opera, Safari
			  xmlhttp=new XMLHttpRequest();
			  }
			else
			  {// code for IE6, IE5
			  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
			  }
			xmlhttp.onreadystatechange=function()
			  {
			  if (xmlhttp.readyState==4 && xmlhttp.status==200)
				{
				document.getElementById("emp_body").innerHTML=xmlhttp.responseText;
				}
			  }
			xmlhttp.open("GET","../xmlData/sample.php",true);
			xmlhttp.send();

The alert() function does nothing to check whether your xmlhttp is working. Is your xmlhttp variable global? In other words, do you declare it somewhere and is being used somewhere else too? The reason is that I do not see you declare the object inside your function at all. In JavaScript, simply use a variable name in a function results in creating/assuming the variable is global - dangerous.

Let see if you actually get xmlhttp object created by inserting alert(xmlhttp) right before line 12.
