Retrieving Array of Objects Sent Using AJAX in JSP

Question

With respect to this question pass array of objects to jsp, how do you retrieve the results in JSP?

The question is, I have this in my Javascript:

data = [
    {
    id: "333",
    date: "22/12/2015"
    },
    {
      id: "333",
      date: "22/12/2015"
    }]

$.post(eval.jsp, {data:data}, function(){}, "json");

How do i recover data in eval.jsp. I tried

request.getParameterValues("data");

But the value returned is null. This is not the value passed of course as can be seen in the headers (using Chrome).

using a for each loop like you do in java. JSP allows embedding java code as well as javascript. In your case it will be a loop processed in javascript. Have a look at this http://stackoverflow.com/questions/14217790/accessing-objects-in-json-array-javascript It is interesting what wonders a little bit of googling can do. — Acewin, Oct 22 '15 at 22:51
same way you do if it is a form, default content type is form encoded — charlietfl, Oct 22 '15 at 23:44
Sounds like you might need a [JSON library for Java](https://www.google.com/search?q=JSON+library+for+Java&ie=utf-8&oe=utf-8) — James, Oct 23 '15 at 00:38

You can use a dynamic table or Foreach to show data in it . Example:

<table id="allStudent" class="table table-bordered">
                <thead>
                <tr>
  <th>FirstName</th>
  <th>LastName</th>
  <th>studentCode</th>
  <th>Major</th>
 <th>FatherName</th>
 <th>id</th>
  <th>Action</th>
     </tr>
        </thead>
           <tbody id="tmplBody">
            <script id="scriptTmp">

               <tr id="deleteTr" >

           <td>
                  ${firstName}

             <td>
                 ${lastName}
                 </td>
                        <td>
                            ${studentCode}
                        </td>
                        <td>
                            ${major}
                        </td>
                        <td>
                            ${fatherName}
                        </td>
                         <td>
                            ${id}
                        </td>
                        <td>

                            <button id="updateStudent" class="btn btn-success"><i class="fa fa-pencil" style="padding-right: 10px;"></i>
                                Update
                            </button>

                            <a href="#" type="button"  class="btn btn-danger deletebtn" role="button" onclick="deleteSt(${id})"><i class="fa fa-trash" style="padding-right: 10px;"></i>
                                Delete
                            </a>
                            <button  class="btn btn-info" role="button"><i class="fa fa-check" style="padding-right: 10px;"></i>Course
                                Selection
                            </button>
                        </td>
                    </tr>

                    </script>
                </tbody>


            </table>

        </div>

I think you have misunderstood the question. It is asking how to retrieve the data sent to jsp in the jsp itself. your answer is about showing a collection in the client side. Also your code doesnt have any loop so i am not exactly sure how it will iterate.. — suvartheec, Jun 12 '18 at 06:11
