Can you give some code examples or sudo code?

<html><head><script>
		
		$(document).ready(function(){

			$("#callPegingId").ajaxError(function(e,xhr,opt){
				alert("Error requesting "+opt.url + ": "+xhr.status+" "+xhr.statusText+" :e = "+e+" "+xhr.responseText);
			})

			$("#callPegingId").change(function(){
					alert("testing hdButtonId.....");
				$.ajax({

					type: "POST",
					data: "sqlQry="+<%=qrySnd%>+"&recSearch="+$(this).val(),
					url: "birthSearchPegination.jsp",
					success: function(result){
						$("#hdButtonId").html(result);
					}
				})
			})
		})

	</script>
</head>
<form>
<input type="hidden" name="callPeging" id="callPegingId" value="check">
<%
// Here is if resultset contain some data then script will be executed

if(rs.next()){%>
											<script>
											    document.getElementById("callPegingId").value = 1;
										
											</script>
									   <%}%>
</form></html>

in the above application if textbox value change to 1 by satisfying if condition and then ajax code should be call.

I think the change event will only fire when there is user interaction (user types into a textbox, selects something in a dropdown...). I think what you want is the following:

function callAjax(value){
	$.ajax({
		type: "POST",
		data: "sqlQry="+<%=qrySnd%>+"&recSearch="+value,
		url: "birthSearchPegination.jsp",
		success: function(result){
			$("#hdButtonId").html(result);
		}
	})
}

...

if(rs.next()){%>
											<script>
											    
callAjax(1);
 
											</script>
									   <%}%>

Thanx for reply,

The method callAjax(int) is undefined

please help me

Show code please.

if I try ur above given solution then it shows me error is "object required" at where we have called callAjax(1) in if condition.

I can't help you if you don't show the code you've changed. Please show all the code.

Perhaps what you need is this:

data: {sqlQry: '<%=qrySnd%>', recSearch: value}
