Use JQuery to call Ajax and dynamically Load Page

Example 1:
<script type="text/JavaScript">
function getTime(){
var ClassDivision = document.getElementById("Class").value;
var chrType = document.getElementById("Type").value;
$.ajax({
type: "POST",
  url: "ajax/ajax_page.php",
    data: 'Class='+Class+'&Type='+Type,
  cache: false,
  success: function(msg){
$("#Name_ID").html(msg);
},
error: function(){
alert('Server Busy');
}
  });

}
</script>




Example 2:


<script language="JavaScript" type="text/JavaScript">

$(document).ready(function () {

$('#intBuilding').change(function(e){
var classid=$(this).val();
$('#RoomNo').load('ajax/ajax_rooms.php?id='+classid);
  });
 
});
</script>
