python django 一个完整的简单的 jquery DataTable 的demo

首先是前端代码吧：

<script src="/static/jquery.min.js" type="text/javascript"></script>
<script src="/static/jquery.dataTables.min.js" type="text/javascript"></script>
<link rel="stylesheet" type="text/css" href="/static/jquery.dataTables.min.css" />
<table id="datatable" width="100%" border="1">
  <thead>
    <tr>
      <th>ID</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Operation</th>
    </tr>
  <thead>
</table>

js代码如下：

$(document).ready(function() {
    $("#datatable").dataTable({
      "processing": true,
      "serverSide": true,
        "ajax": {
             url: "/ajax_json",
             type: "post",
            dataType: "json",
        },
      "columns": [
        {"data": "id", "bSortable": false},
        {"data": "firstName"},
        {"data": "lastName"}
      ],
      "columnDefs": [
        {
          "targets": [3],
          "data": "id",
          "render": function(data, type, full) {
            return "<a href='/update?id=" + data + "'>Update</a>";
          }
        }
      ]
    });
  });

后端代码如下：

def ajax_json(request):
    rsp = {"draw":2,"recordsTotal":11,"recordsFiltered":11,"data":[{"id":1,"firstName":"Troy","lastName":"Young"},{"id":2,"firstName":"Alice","lastName":"LL"},{"id":3,"firstName":"Larry","lastName":"Bird"},]}
    return HttpResponse(json.dumps(rsp), content_type="application/json")

一个非常小的demo,先run起来，其它的都是小事。
后续：
接下里是丰满整个流程，前端传给后端的参数很多，但是重要的就那么几个：
draw是请求的序号，start是数据的起始，length是需要返回的最大数据条数。search[value]是查找的值
