jQuery Filter Table Plugin

This plugin will add a search filter to tables. When typing in the filter, any rows that do not contain the filter will be hidden.

One can also define clickable shortcuts for commonly used terms.

See the demos at http://sunnywalker.github.com/jQuery.FilterTable

Usage

Include the dependencies:

<script src="/path/to/jquery.js"></script>
<script src="/path/to/bindWithDelay.js"></script> <!-- optional -->
<script src="/path/to/jquery.filtertable.js"></script>
<style>
.filter-table .quick { margin-left: 0.5em; font-size: 0.8em; text-decoration: none; }
.fitler-table .quick:hover { text-decoration: underline; }
td.alt { background-color: #ffc; background-color: rgba(255, 255, 0, 0.2); }
</style> <!-- or put the styling in your stylesheet -->

Then apply filterTable() to your table(s):

<script>
$('table').filterTable(); //if this code appears after your tables; otherwise, include it in your document.ready() code.
</script>

Options

Option	Type	Default	Description
autofocus	boolean	false	Makes the filter input field autofocused (not recommended for accessibility reasons)
callback	function(term, table)	null	Callback function after a filter is performed. Parameters: term filter term (string) table table being filtered (jQuery object)
containerClass	string	filter-table	Class applied to the main filter input container
containerTag	string	p	Tag name of the main filter input container
hideTFootOnFilter	boolean	false	Controls whether the table's tfoot(s) will be hidden when the table is filtered
highlightClass	string	alt	Class applied to cells containing the filter term
inputSelector	string	null	Use this selector to find the filter input instead of creating a new one (only works if selector returns a single element)
inputName	string	filter-table	Name attribute of the filter input field
inputType	string	search	Tag name of the filter input itself
label	string	Filter:	Text to precede the filter input
minRows	integer	8	Only show the filter on tables with this number of rows or more
placeholder	string	search this table	HTML5 placeholder text for the filter input
preventReturnKey	boolean	true	Trap the return key in the filter input field to prevent form submission
quickList	array	[]	List of clickable phrases to quick fill the search
quickListClass	string	quick	Class of each quick list item
quickListGroupTag	string	''	Tag name surrounding quick list items (e.g., ul)
quickListTag	string	a	Tag name of each quick list item (e.g., a or li)
visibleClass	string	visible	Class applied to visible rows

Styling

Suggested styling:

.filter-table .quick { margin-left: 0.5em; font-size: 0.8em; text-decoration: none; }
.fitler-table .quick:hover { text-decoration: underline; }
td.alt { background-color: #ffc; background-color: rgba(255, 255, 0, 0.2); }

There is a caveat on automatic row striping. While alternating rows can be striped with CSS, such as:

tbody td:nth-child(even) { background-color: #f0f8ff; }

Note that CSS cannot differentiate between visible and non-visible rows. To that end, it's better to use jQuery to add and remove a striping class to visible rows by defining a callback function in the options.

$('table').filterTable({
    callback: function(term, table) {
        table.find('tr').removeClass('striped').filter(':visible:even').addClass('striped');
    }
});

Dependencies

Other than jQuery, the plugin will take advantage of Brian Grinstead's bindWithDelay if it is available.

Change Log

1.5.4

• Added a return key trap to the input filter field so that pressing return in the field should not submit any forms the table may be within.
• The preventReturnKey option (true by default) has been added to allow you to switch back to the previous behavior of allowing the return key to submit forms.

1.5.3

• There is a potentially significant change in functionality in this version. While the documentation offered the inputSelector option, within the code it was implemented as filterSelector. This has been corrected to match the documentation. Note that if you were previously using the filterSelector option to overcome this issue, you will need to change it to inputSelector to use the feature with this version.

1.5.2

• Added an inputSelector option, thanks to Pratik Thakkar, which specifies a selector for an existing element to use instead of creating a new filter input field. There are some caveats of which to be aware:
  • If the element doesn't exist, a filter input field will be created as normal.
  • Because of quick lists and other options, this setting will be ignored and the filter input field will be created as normal if the resolution of the inputSelector returns more than one element.

1.5.1

• Added an autofocus option, thanks to Robert McLeod, which is disabled by default. Note that autofocus is generally a bad idea for accessibility reasons, but if you do not need to be compliant or don't want to support accessibility users, it's a nice user experience option.

1.5

• There is a potentially significant change in functionality in this version. The callback is now called every time the search query changes. Previously it was only called when the change was a non-empty query. That is, the callback is now called when the query is cleared too.
• Additional features have been taken from Tomas Celizna's CoffeeScript-based fork:
  • The quick list items can now be something other than anchor tags. See the quickListTag and quickListGroupTag options.
  • The filter query field can now have a name attribute assigned to it. See the inputName option.
  • The class applied to visible rows is now user changeable. See the visibleClass option.
  • The options in the documentation have been ordered alphabetically for easier scanning.
• The internal pseudo selector is now created appropriately according to the jQuery version. (Pseudo selector generation changed in jQuery 1.8)

1.4

• Fixed a bug with filtering rarely showing rows that did not have a match with the search query.
• Added example pages.
• Improved inline documentation of the source code.

1.3.1 (in spirit)

• Added minified version of the plugin (thanks Luke Stevenson).

1.3

• The functionality is not reapplied to tables that have already been processed. This allows you to call $(selector).filterTable() again for dynamically created data without it affecting previously filtered tables.

1.2

• Changed the default container class to filter-table from table-filter to be consistent with the plugin name.
• Made the cell highlighting class an option rather than hard-coded.

1.1

• Initial public release.
