我正在使用 DataTables 成功显示超过 100k 条记录，但现在我无法向表添加自定义链接，因为它是用 JavaScript 生成的，我有点迷路了。 我想要实现的是最后一列显示类似于此的链接:a href="index.php?edit=ID" 其中 id 是 id 来自分贝。

最佳答案

检查 fnRowCallback here .

$(document).ready(function() {
  $('#example').dataTable( {
    "fnRowCallback": function( nRow, aData, iDisplayIndex, iDisplayIndexFull ) {
      // Bold the grade for all 'A' grade browsers
      if ( aData[4] == "A" )
      {
        $('td:eq(4)', nRow).html( '<b>A</b>' ); // You can add your link here!!
//like $('td:eq(4)', nRow).html( '<a href="'+ aData[4] +'">Click Here</b>' );
       }
    }
  } );
} );

aData 是一个对象，它包含在数组中，每行包含来自您的服务器的内容。所以在你的情况下它可能不一定是 aData[4]，它可能是 1,2,3 取决于你的 在哪个 column >id 来了。

您可以在您的案例中执行 console.log(aData) 来分析您的 ID 位于哪一列! (为此你需要 firebug)

td:eq(4) 也是您希望显示链接的列。
