## Filter Widget

### Flexible client-side table sorting

Back to documentation

### Notes

- Hover over the grey bar below the table header to open the filter row. Disable this by setting `filter_hideFilters` option to `false`.
- This widget uses jQuery's `.nextUntil()` function which is only available is jQuery version 1.4+.
- This widget does work with tablesorter v2.0.5.
- Using the filters:

  Type (1) | Description | Example
  text | Any text entered in the filter will match text found within the column | `abc` (finds "abc", "abcd", "abcde", etc)
  `"` | To exactly match the search query, add a quote, apostrophe or equal sign to the beginning and/or end of the query | `abc"` or `abc=` (exactly match "abc")
  `?` | Wildcard for a single, non-space character. | `J?n` (finds "Jan" and "Jun", but not "Joan")
  `*` | Wildcard for zero or more non-space characters. | `B*k` (matches "Black" and "Book")
  `/\d/` | Add any regex to the query to use in the query | `/b[aeiou]g/i` (finds "bag", "beg", "BIG", "Bug", etc)
  `< <= >= >` | Find alphabetical or numerical values less than or greater than or equal to the filtered query (2). | `>= 10` (find values greater than or equal to 10)
  `!` | Not operator. Filter the column with content that do not match the query. | `!fe` (hide rows with "female" in that column, but shows rows with "male")
  `&&` or `AND` | Logical "and". Filter the column for content that matches text from either side of the operator. | `box && bat` (matches a column cell that contains both "box" and "bat")
  `|` or `OR` | Logical "or" (Vertical bar). Filter the column for content that matches text from either side of the bar (3). | `box|bat` (matches a column cell with either "box" or "bat")
  `-` or `to` | Find a range of values. Make sure there is a space before and after the dash (or the word "to") (2). | `10 - 30` or `10 to 30` (match values between 10 and 30)

  (1) You cannot combine these operators with each other (except for the wildcards).
  (2) In tablesorter v2.10, comparisons can be made in date columns (if properly parsed).
  (3) Logical "or" comparisons can now show exact matches (by default; v2.10.1) or just match cell contents.

### Options

### Filter widget defaults (added inside of tablesorter `widgetOptions`)

- `filter_childRows : false` - if true, filter includes child row content in the search.
- `filter_columnFilters : true` - if true, a filter will be added to the top of each table column.
- `filter_cssFilter : ''` - extra css class name added to the filter row & each input in the row.
- `filter_filteredRow : 'filtered'` - css class name added to filtered rows (rows that are not showing); needed by pager plugin.
- `filter_formatter : null` - add custom filter elements to the filter row.
- `filter_functions : null` - add custom filter functions using this option.
- `filter_hideFilters : false` - if true, filters are hidden initially, but can be revealed by clicking on the filter icon *.
- `filter_ignoreCase : true` - if true, make all searches case-insensitive.
- `filter_liveSearch : true` - if true, search column content while the user types (with a delay). If false, the user must press enter to start the search. If set to a number, when the length of the input text reaches this minimum length, a search will initiate.
- `filter_onlyAvail : 'filter-onlyAvail'` - a header with a select dropdown & this class name will only show available (visible) options within that drop down.
- `filter_reset : null` - jQuery selector string of an element used to reset the filters.
- `filter_searchDelay : 300` - typing delay in milliseconds before starting a search.
- `filter_serversideFiltering : false` - if true, filter will be done server-side. The client-side filtering will be disabled, but the ui and events will still be used.
- `filter_startsWith : false` - if true, filter start from the beginning of the cell contents.
- `filter_useParsedData : false` - filter all data using parsed content.

### Classes

Class names that can be added to the `th` header cells:

- `filter-false` - disable the filter for a specific header column.
- `filter-select` - build a default select box for a column (shows unique column content). See the custom filter widget demo for an example.
- `filter-match` - applies to "filter-select" columns and columns where the user can use the logical "or" search. Makes the filter/select match the column contents instead of exactly matching.
- `filter-parsed` - set a column to filter through parsed data instead of the actual table cell content.
- `filter-onlyAvail` - show only available (visible) options within a default select box. See the custom filter widget demo "Discount" column for an example.

### Methods

### filterReset

> Use the `filterReset` method to reset (clear) all of the current filters using this method

>     $('table').trigger('filterReset');

### search

> With this method, you can pass an array of filter values:

>     // apply "2?%" filter to the fifth column (zero-based index)
>     var columns = [];
>     columns[5] = '2?%';
>     // or define the array this way var columns = [ '', '', '', '', '', '2?%' ]
>     $('table').trigger('search', [ columns ]);

> or, just pass `false` to refresh the current search:

>     $('table').trigger('search', false);

> * Note: using this search method will not update the contents of the filters within the filter row; use the `$.tablesorter.setFilter()` method below to do that.

### Get current filters

> Get an array of the currently applied filters (v2.9).

>     $.tablesorter.getFilters( $('table') ); // or $('table.hasFilters')

> This method returns an array of filter values or `false` if the selected table does not contain a filter row.

### Set current filters

> Set the values of the actual filters using this method; include a `true` boolean to actually apply the search (v2.9).

>     // update filters, but don't apply the search
>     $.tablesorter.setFilters( $('table'), [ '', '', '', '', '', '2?%' ] );

>     // update filters, AND apply the search
>     $.tablesorter.setFilters( $('table'), [ '', '', '', '', '', '2?%' ], true );

> This method returns `true` if the filters were sucessfully applied, or `false` if the table does have a filter row.

### Events

- `filterEnd` - Event triggered when the filter widget has finished processing the search.
- `filterInit` - Event triggered when the filter widget has finished initializing.
- `filterStart` - Event triggered when the filter widget has started processing the search.

### Changes

Moved to the wiki pages - filter change log.

# Demo

filter_startsWith : false (if true, search from beginning of cell content only)
filter_ignoreCase : true (if false, the search will be case sensitive)
filter-match (if class name added to the "First Name" column, all "or" searches will only match the content; Search
in the First Name column (2.10.1).

(search the Discount column for "2?%")
