Я пытаюсь отправить некоторые данные из JSP в сервлет, используя JQuery/Ajax. Ниже приведены важные элементы моего файла JSP.
script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
var form = $('#customItemForm');
form.submit(function () {
$.ajax({
type: form.attr('method'),
url: form.attr('action'),
data: form.serialize(),
success: function (data) {
}
});
return false;
});
</script>
<!--add custom item -->
<div class="modal fade" id="customItemModel" tabindex="-1" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header"> <a href="#" data-dismiss="modal"> <img src="images/arrow-back-512.png" width="30px" height="30px"> <small>Back</small></a> <span id="myModalLabel" style="margin-left:20px;"><font size="+2"><b>Add Custom Item</b></font></span> </div>
<div class="modal-body">
<form class="form-horizontal" name="customItemForm" method="post" action="PastSurgicalCustomItem">
<fieldset id="modal_form">
<!-- Text input-->
<div class="form-group">
<label class="col-md-1 control-label" for="textinput">Name</label>
<div class="col-md-8">
<input id="customName" name="customName" type="text" placeholder="" class="form-control input-md">
</div>
</div>
<div class="modal-footer">
<input type="submit" id="additional" class="btn btn-primary" data-dismiss="modal" value="Submit">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
</div>
</fieldset>
</form>
</div>
</div>
</div>
<!-- /add custom item -->
Ниже приведен класс сервлета
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class PastSurgicalCustomItem extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String customName = request.getParameter("customName");
System.out.println(customName);
}
// <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
/**
* Handles the HTTP <code>GET</code> method.
*
* @param request servlet request
* @param response servlet response

* @throws IOException if an I/O error occurs
*/
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Handles the HTTP <code>POST</code> method.
*
* @param request servlet request
* @param response servlet response

* @throws IOException if an I/O error occurs
*/
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
/**
* Returns a short description of the servlet.
*
* @return a String containing servlet description
*/
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}
Однако сервлет не печатает значение, что означает, что JQuery ничего не передал. Что я здесь сделал не так?
