Using jQuery-ajax, i am trying to develop an application. I want to delete districts from database table named district_details. I am showing districts in tabular format as an user interface and provided a checkbox against each and every district. On click of Delete button i want to delete selected districts from table. But at a time, i can delete only 1 district from database. Multiple districts can not be deleted. I am providing with the code snippet. so please help.


<script type="text/javascript">
$('#myDiv1').load('http://localhost:8080/statsdept/admin/showDistrict.jsp');// showing the //districts
$('#myDiv2').load('http://localhost:8080/statsdept/addDistrict', //for adding district
{ name: $("#district").val()});

$("#Delete").click(function(){ // delete districts
var selectedItems = new Array();
$("input[@name='courseCb[]']:checked").each(function() {selectedItems.push($(this).val());});
if (selectedItems .length == 0)
alert("Please select item(s) to delete.");
type: "POST",
url: "http://localhost:8080/statsdept/delDistrict",
data: "items=" + selectedItems,
dataType: "text",
success: function (request) {

error: function(request,error){
alert('Error deleting item(s), try again later.');
});//end of trial button clicked function.

});//end of document.ready function.


<p class="msg_head">District Info</p>

<div class="msg_body">

<div id="myDiv1"></div>
<button id="Delete" type="button">Delete District</button><br>
District Name : <input type="text" id="district"><br>
<button id="b01" type="button">Add District</button>
<div id="myDiv2"></div>


try {
String[] sr_nos = request.getParameterValues("items"); //value from checkbox
//String[] sr_nos = {"32","35"}; //value from checkbox
out.println("<title>Servlet delDistrict</title>");

dbCon dc = new dbCon();
Connection con = dc.getConnection1();

Statement stmt = con.createStatement();
int arrayElement = 0;
for(int i = 0; i<sr_nos.length; i++){
//out.println("<script>alert(" + sr_nos[i] + ")</script>");
arrayElement = Integer.parseInt(sr_nos[i]);
stmt.executeUpdate("delete from district_details where dst_id = " + arrayElement);
catch(Exception e){

use $.post() for jquery ajax and pass your selected value as parameter of ajax call

are you getting array at server side?

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is unnecessarily difficult to read. You can edit your post by using the button.
