我想通过在特定索引上添加key => value对来更新datatable对象，例如 - 下面是我的datatable对象值。所以我只想在jquery的列[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.-
Array
(
[draw] => 2
[columns] => Array
(
[0] => Array
(
[data] => 0

[searchable] => true
[orderable] => true
[search] => Array
(
[value] =>
[regex] => false
)
)
[1] => Array
(
[data] => 1
[name] =>
[searchable] => true
[orderable] => true
[search] => Array
(
[value] =>
[regex] => false
)
)
[2] => Array
(
[data] => 2
[name] =>
[searchable] => true
[orderable] => true

答案
如果要向服务器提交其他键/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();
}
}
} );
