如何从 jquery 更新数据表对象

Question

我想通过在特定索引上添加 key=>value 对来更新数据表对象，例如 - 下面是我的数据表对象值。所以我只想在 jquery 的 column[0]['search'] 索引下添加一个键值对。我试过这个 dataTable.columns(0).search({"Key":"value"}).draw();但它不起作用。-

如果您想向服务器提交额外的键/值对，请使用ajax.data 选项。

例如：

$('#example').dataTable( {
  "ajax": {
    "url": "data.json",
    "data": function ( d ) {
        d.extra_search = $('#extra').val();
    }
  }
} );
