jquery , ajax code table :- 

 $('#paymentdetails').click(function(){  					if( $(".datepickerinputfrom").val() > $(".datepickerinputto").val())  						{  						alertify.alert('from date should not greater  date')  						return false;  						$(".datepickerinputfrom").val ="";  						}  					var getdata = basepath +'adminfinance/getstudentpaymentsfordate/?fromdate='+$(".datepickerinputfrom").val() + '&todate='+$(".datepickerinputto").val()  					    					  if (($(".datepickerinputfrom").val() == "") && ($(".datepickerinputto").val() == ""))  					  {                               alertify.alert('please select dates proceed.')  							return false;  					  } else if (($(".datepickerinputfrom").val() == "") || ($(".datepickerinputto").val() == ""))  					  {                               alertify.alert('please select dates proceed.')  							return false;  					  }  				                                              				$.ajax({                          url: getdata                           , async: false                          , success: function (response) {                             //  alert(response[0]);                              //$('#financetbl tbody').empty();  							$('#financetbl tbody').empty();  							                             // if (response.resultcourse != '' && response[0]!= 'null') {  						    if (response.length > 0) {                               var tr;                                   (var = 0; < response.length; i++) {                                   tr = '<tr>'                                   tr += "<td>" + response[i].transactiondate+ "</td>";                                   tr += "<td>" + response[i].applicationnumber+ "</td>";                                   tr += "<td>" + response[i].applicantname+ "</td>"                                                                   tr += '</tr>'                                  $('#financetbl tbody').append(tr);  								}  								  								inittable();                                 console.log(response)  							                                }                              else {  								console.log(response)                                  alertify.alert("error : no payments details found");  								  								inittable();  								                              }                          }                      });  				});

i have tried below option nothing working me.

`$("#tbodyid tr").detach();  $("#tbodyid tr").remove();  $("#tbodyid").empty();  $("#tbodyid").html("");  $("tbody").empty();  $("tbody").html("");  $('#table').datatable().fndraw(false)`

you wanna de-initialize table data when there no data? try this?

// destroy first $('#yourtableid').datatable().fndestroy(); // initialize table again $('#yourtableid').datatable({ ... });
