Question

Scenario:

I need to filter out data from the datatable based on the selection that has been made from the user. To implement this I have a tree control which represents the hierarchy of the data in the datatable. When a user unchecks a certain node in the tree. That data should be taken out from the datatable.

Question:

How do I filter "out" data from the datatable?
If I use search() method, it gives me that matched rows and I want the opposite of this. I need to take out the matched rows instead of showing them.
I tried using the following filter function but it gives me the filtered data.
```
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}
```

I would appreciate any help on this.

Thanks

Answer 1

简单的答案是反转过滤器。即更改过滤器以返回false，其中当前返回true，反之亦然。

您也可以通过反转您要查找的正则表达式来搜索。

Answer 2

您可以实现自己的自定义搜索功能：

＆＃13;

var table = $('#myTable').DataTable();

$.fn.dataTable.ext.search.push(
  function(oSettings, aData, iDataIndex) {
    var match = true;
    $(".checkbox:checked").each(function(index) {
      var cb = $(this);
      var id = $(this).attr('id');

      if (aData.toString().toLowerCase().indexOf(id) >= 0) {
        match = false;
      } else {
        match = true;
      }
    });
    return match;
  });
