jQuery中Datatables增加跳转到指定页功能

下面一段代码是关于datatable增加跳转到指定页功能，具体代码如下所示：

var
mytable = $('#datatables');
  mytable.dataTable(
 {
    "sDom":
"<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
    "sPaginationType":
"bootstrap",
    "bProcessing":
true,
    "bServerSide":
true,
    "sAjaxSource":
"/user/list",
    "aoColumns":
 [
      {
"mData":
"Id"
},
      {
"mData":
"Username"
},
      {"mData":function(obj){
        return
obj.group;
      }},
      {"mData":"yiyuan"},
      {"mData":function(obj){
        return
obj.keshi;
      }},
      {"mData":function(obj){
        if(obj.Status==1){
          return
"使用中";
        }else{
          return
"禁用";
        }
      }},
      {"mData":
function(obj){
        var
del="";
        if(isAdmin){
          del='<a
 data-title="'
+ obj.Id + '"
 class="btn btn-danger"><i class="icon-wrench icon-white" ></i>删除</a>';
        }
       return
'<a data-title="'
+ obj.Id + '"
 class="btn btn-success" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><i class="icon-edit icon-white"></i>修改</a>'
+'  '+del;
      },bSortable
 : false}
    ],
    "fnDrawCallback":
function(){
      var
oTable = $("#datatables").dataTable();
      $('#redirect').keyup(function(e){
        if($(this).val()
 && $(this).val()>0){
          var
redirectpage = $(this).val()-1;
        }else{
          var
redirectpage = 0;
        }
        oTable.fnPageChange(
 redirectpage );
      });
    }
   });

好了，下面看下jQuery datatable中加入双击跳转功能

$('#topicDg tbody').on('dblclick','tr',function(){
 var self=$(this);
 var id=self.find('.td-id').text();
 var name=self.find('.td-name').text();
 creatIframe("/post/postList.do?id="+id+"&name="+name,"帖子管理");
}); 

ps:点击话题列表中的一行，跳转到帖子列表中。
