jQuery plugin: Tablesorter 2.0 - Filter Widget

# tablesorter

## Filter Widget

### Flexible client-side table sorting

Back to documentation

### Notes

- In v2.18.0, added `filter_cellFilter` & the ability to set multiple "any" match columns for an external search (see the external inputs demo for more details).
- In v2.17.8, filter selects will default to exact matches unless the header cell has a "filter-match" class added.
- In v2.17.1, added a not exact match (`!=`) filter type.
- In v2.16+,
  - When a default filter select is added to a column, it is now parsed from the assigned parser, then sorted using the `textSorter` setting, and falls back to an alphanumeric sort (v2.16.3).
  - Adding a class of `"filter-select-nosort"` will now leave the select options unsorted (v2.16.3).
  - Added `filter_placeholder` option (v2.16.0).
  - Added `filter_selectSource` option (v2.16.3).
  - updated `filter_reset` option (v2.16.3).
- In v2.15,
  - The `filter_anyMatch` widget option was completely removed. Sorry for not deprecating this option, but the filter any match code was completely rewritten.
  - Added a `filter_external` widget option to only accept a jQuery selector string/object; please see the updated filter any match demo for more details.
- Added & set `filter_saveFilters` to `true` (default is `false`) in this demo (v2.14).
- 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 built-in filters (learn how to customize them here - demo created v2.17.5):

  Type (1)(2) | Description | Examples
  --- | --- | ---
  text | Any text entered in the filter will match text found within the column | `abc` (finds "abc", "abcd", "abcde", etc); (finds "Aaron" and "Philip Aaron Wong")
  `/\d/` | Add any regex to the query to use in the query ("mig" flags can be included `/\w/mig`) | `/b[aeiou]g/i` (finds "bag", "beg", "BIG", "Bug", etc); (matches text that ends with an "r")
  `< <= >= >` | Find alphabetical or numerical values less than or greater than or equal to the filtered query (2). | (find values greater than or equal to 10)
  `!` or `!=` | Not operator, or not exactly match. Filter the column with content that do not match the query. Include an equal (`=`), single (`'`) or double quote (`"`) to exactly not match a filter (v2.17.1). | `!fe` (hide rows with "female" in that column, but shows rows with "male"); (find text that doesn't contain an "a"); (find content that does not exactly match "Bruce")
  `"` or `=` | 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"); or (exactly match "John")
  `&&` 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"); (Find text that contains both "br" and "c")
  `-` or `to` | Find a range of values. Make sure there is a space before and after the dash (or the word "to") (4). | or (match values between 10 and 30)
  `?` | Wildcard for a single, non-space character. | `J?n` (finds "Jan" and "Jun", but not "Joan"); (finds "Dumass" and "Evans", but not "McMasters")
  `*` | Wildcard for zero or more non-space characters. | `B*k` (matches "Black" and "Book"); (matches "Dumass", "Evans" and "McMasters")
  `|` 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"); (Find text that contains either "Alex" or "Peter")
  `~` | Perform a fuzzy search (matches sequential characters) by adding a tilde to the beginning of the query (v2.13.3) | (matches "Bruce Lee" and "Brenda Dexter"), or (matches "Philip Aaron Wong")

  (1) You cannot combine these operators with each other (except for the wildcards).
  (2) The filter order (or precendence) of how searches are checked is as follows: regex (`/\d/`) > operators (`< <= >= >`) > not match (`!`) > exact (`"`) > and (`AND` ) > range (`-` ) > wild/or (`?`, `*` and `OR` ) > fuzzy (`~`); so an exact match will override "and", "or" and "range" searches (*NOTE* order changed in v2.15, operators prioritized before exact; see issue #465; order changed again in v2.17.1 to move "not match" before "exact" and allow for exact not matches; see issue #628)
  (3) Logical "or" comparisons can now show exact matches (by default; v2.10.1) or just match cell contents.
  (4) In tablesorter v2.10, comparisons can be made in date columns (if properly parsed).

### Options

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

TIP! Click on the link in the function column to reveal full details (or toggle|show|hide all) or double click to update the browser location.

Option | Default | Description
--- | --- | ---
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_columnAnyMatch | true | if `true`, allows using "#:{query}" in anyMatch searches (v2.20.0). Users can use the anymatch input to target a specific column, using a one-based index. For example: In the table below, searching for `2:aa` in an anymatch filter will result in "Phillip Aaron Wong" and "Aaron" showing in the First Name column. See live examples in the Filter Widget External Search demo.
filter_cellFilter | '' | Extra css class name added to the filter cell (string or array) (v2.18.0) The filter cell (`<td>`) is not to be confused with the `filter_cssFilter` option which adds an extra class name to the filter inputs (`<input>`).
filter_cssFilter | '' | Extra css class name(s) applied to the table row containing the filters & the inputs within that row (v2.15). This option can either be a string (class applied to all filters) or an array (class applied to indexed filter).
filter_defaultAttrib | 'data-value' | this option contains the name of the data-attribute which contains the default (starting) filter value.
filter_defaultFilter | { } | Set a default filter for a set column (v2.17.8).
filter_excludeFilter | { } | Set a column to exclude the chosen filter types (range, exact, notMatch, etc) (v2.17.8).
filter_external | '' | Set to a jQuery selector (or object) pointing to an input to be used to match the contents of any column (v2.15). Please refer to the updated filter-any-match demo for the limitations of this setting.
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 element(s) to the filter row Custom filter elements include: jQuery UI widgets: slider, spinner & datepicker HTML5 elements: range, number input, color selector. Select2 plugin.
filter_functions | null | Add custom filter functions using this option. See the custom filter widget functions demo for more details and numerous examples.
filter_hideEmpty | true | Hide filter row when the table is empty (v2.15).
filter_hideFilters | false | If `true`, filters are hidden initially, but can be revealed by hovering over the filter row, or giving a filter input focus (tabbing down the page).
filter_ignoreCase | true | If `true`, all searches are case-insensitive.
filter_liveSearch | true | If `true`, search column content while the user types (with a short 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 set, will only show available (visible) options within that drop down.
filter_placeholder | { search : '', select : '' } | Default placeholder text (overridden by any header "data-placeholder" setting; v2.16).
filter_reset | null | jQuery selector string of an element used to reset the filters (v2.4; v2.16.0).
filter_saveFilters | false | Uses the `$.tablesorter.storage` utility to save the most recent filters.
filter_searchDelay | 300 | Typing delay in milliseconds before starting a search.
filter_searchFiltered | true | Allow searching through already filtered rows in special circumstances; will speed up searching in large tables if `true`.
filter_selectSource | null | Include a function to return an array of values to be added to the column filter select (v2.16.0).
filter_selectSourceSeparator | null | `filter_selectSource` array text left of the separator is added to the option value, right into the option text.
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.
Removed options
filter_anyMatch | null | jQuery selector string (or jQuery object) of external anyMatch filter (removed in v2.15; please see the demo for more details)

### 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-select-nosort` - when a default select box is built, this option prevents the sorting of select options leaving them in their original table order (v2.16.3).
- `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.
  - This class name is set by the `filter_onlyAvail` option.
  - See the custom filter widget demo "Discount" column for an example.

### Methods

### Set Filter Placeholder Text

> Set a `data-placeholder` attribute on the associated table header with your desired placeholder text

>     <th data-placeholder="Enter Something">Name</th>

> or, set the header cell's jQuery data

>     $('.tablesorter th:eq(0)').data('placeholder', 'Search for...')

### 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 update the contents of the filters within the filter row.
> In v2.15, one additional parameter can be added to the array to perform an "any-match" of the table; Warning! please note that if no external input (with a `data-column="all"` is attached using `bindSearch` function) is visible, the user will not know that a filter has been applied.

>     // in a table with 4 columns; set the 5th parameter to any-match
>     $('table').trigger( 'search', [['', '', '', '', 'orange']] ); // find orange in any column

### 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.
> Internally, the get filters functions returns the filters stored within this table data `$('table').data('lastSearch')`, unless an additional parameter of `true` is passed to the function:

>     $.tablesorter.getFilters( $('table'), true ); // get current input values instead of data stored filters

> As of v2.15, if an external "any-match" filter (see `filter_external` widget option) is included, one additional array parameter will be returned in the filter - the value of the any match search.

>     // in a table with six columns, this function will return an array with seven
>     // parameters; something like this: [ '', '', '', '', '', '', '11' ],
>     // where the "11" will be obtained from the "any-match" input
>     var filters = $.tablesorter.getFilters( $('table') );

### 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.
> As of v2.15, if an external "any-match" filter (see `filter_external` widget option) is included, add an additional array parameter to set that filter; so if a table has six columns, add the any-match search as the seventh value.

>     // in a table with 6 columns, the 7th filter will apply
>     // to the any-match filter & match any table column with "11"
>     $.tablesorter.setFilters( $('table'), [ '', '', '', '', '', '', '11' ], true );

### Bind External filter

> Use this method to bind external search filters
> - Include a data-attribute `data-column` with the column index to target
> - Or, use `data-column="all"` to preform an "any-match" search on all of the table columns (v2.15).
> - Or, add multiple columns `data-column="0-2,4,6-8"` to perform an "any-match" search on selected columns (v2.18.0).
> If no `data-column` is added to the input, the input will be ignored.

>     <!-- will perform an "any-match" type of search (matches any column) -->
>     <input type="search" class="search" data-column="all">
>     <!-- will only search the first column (zero-based index) -->
>     <input type="search" class="search" data-column="0">

>     // Target the $('.search') input using built in functioning
>     // this binds to the search using "search" and "keyup" and allows using filter_liveSearch
>     // or delayed search & pressing escape to cancel the search
>     // pass an optional third parameter (false boolean) to force the inputs to update
>     // this allows changing the data-column for an input dynamically
>     $.tablesorter.filter.bindSearch( $table, $('.search'), false );

> If you don't care about the enhanced search filter, then bind to both the "keyup" and "search" events

>     // Basic search binding, alternate to the above
>     // bind to search - pressing enter and clicking on "x" to clear (Webkit)
>     // keyup allows dynamic searching
>     $(".search").bind('search keyup', function (e) {
>       $('table').trigger('search', [ [this.value] ]);
>     });

### 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.

### Localization

You can now change the language of the searches used within the filter widget. For example, to change the localization to French, do the following:

    // add French support
    $.extend($.tablesorter.language, {
    	to  : 'à',
    	or  : 'ou',
    	and : 'et'
    });

If you want to support multiple languages, separate the language variables with a vertical bar (`|`, `Shift` + `\`):

    // add French & Spanish support
    $.extend($.tablesorter.language, {
    	to  : 'à|a',
    	or  : 'ou|o',
    	and : 'et|y'
    });

Note These changes still require the user to enter spaces in the filter to perform the search, e.g. `1 à 10` (shows rows with numbers between 1 and 10).

# 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).
