我使用DataTables
以成功显示100k +记录,但现在我无法添加自定义链接到表,因为使用JavaScript生成的地方有点丢失。 我想实现的是显示类似于此的链接的最后一列:a href="index.php?edit=ID"
其中id是来自db的id
。DataTables服务器端链接处理
你可以看到在这个下面使用的PHP和HTML:

它的工作原理,但我不能生成每行的ID。我试过:$('td:eq(6)',nRow).html('Edit'); //你可以在这里添加你的链接!但没有成功 – user1164474 2012-03-01 06:47:39
非常感谢。祝您有个美好的一天 – user1164474 2012-03-01 06:51:32
