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>

Problems?

Be sure to check the FAQ file for common issues if the plugin does not seem to be working as intended.

Note that the plugin does not work as expected when using cells with rowspan.

Options

highlightClass string alt Class applied to cells containing the filter term
ignoreClass string '' Ignore any cells with this class when filtering

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.
