數據表清除搜索輸入和正則表達式

Question

我正在使用帶有正則表達式過濾功能的數據表。 除了一件小事，所有人都按預期工作。

當我搜索術語時，表已成功過濾。 但是，每當我單擊搜索框以外的任何位置時，搜索詞前都會有一個\\b 。

例如，搜索Lon ，然后單擊搜索輸入。 您將看到，然后將其更改為\\bLon 。

我不確定為什么會發生這種情況。 到目前為止，也許有人可以看一下我的代碼，發現我（顯然）缺少的東西！

Jsfiddle在這里 。

到目前為止，我的代碼；

  // DataTable var table = $('#example').DataTable(); $('.dataTables_filter input').unbind().bind('keyup change', function(e) { var searchTerm = this.value.toLowerCase(), regex = '\\\\b' + searchTerm + ''; table.rows().search(regex, true, false).draw(); });

Answer 1

您正在使用regex = '\\\\b' + searchTerm + ''; （可能是為了刪除空格）請使用regex = searchTerm;刪除它regex = searchTerm; 我們可以搜索記錄。
