显示记录“全部”时启用数据表分页“下一步”。如何禁用它？

目前正在研究数据表插件1.9.4。 下面是数据表初始化代码：

oTable = $('#tablename').dataTable({ "aLengthMenu": [ [5, 15, 20, -1], [5, 15, 20, "All"] // change per page values here ], "sPaginationType": "bootstrap", "oLanguage": { "sLengthMenu": "_MENU_ records per page", "sSearch" : "Search records:", "oPaginate": { "sPrevious": "Prev", "sNext": "Next" } }, }); 

问题：

当选择显示5,15,20记录时，“下一步”被禁用，但当我试图显示“全部”时，仍然启用了下一步。

这是你链接更新的jsfiddle与固定代码http://jsfiddle.net/tNXnB/6/
