Client side searching of a table with jQuery

Assume I have a standard HTML table structure like:

<table class="table table-striped table-hover table-bordered table-condensed">
<thead>
    <tr>
        <th>Name</th>
        <th>Type</th>
        <th>Added</th>
    </tr>
</thead>
<tbody>
    <tr id="1a0daa2734" class="item">
        <td><a href="/view/1a0daa2734">Item Number 1</a></td>
        <td>A</td>
        <td>8/1/2012 10:18:34 PM</td>
    </tr>
    <tr id="b1ff6e0ac" class="item">
        <td><a href="/view/b1ff6e0ac">Item Number 2</a></td>
        <td>B</td>
        <td>8/2/2012 5:48:54 PM</td>
    </tr>
    <tr id="edd8b70893" class="item">
        <td><a href="/view/edd8b70893">Item Number 3</a></td>
        <td>A</td>
        <td>8/13/2012 3:55:41 PM</td>
    </tr>
</tbody>
</table>

I am trying to write client side searching with jQuery. Basically I have a search box with an id of search-items.

    $("#search-items").bind("keyup paste", function() {
        var searchText = $("#search-items").val(); 

        $(".item").each(function() {
             //???
        });
    });

What is the best way to take the search value of search-items and find the NON-MATCHES inside of the tbody? I want the non-matches, because those are the elements I will hide.

It should only search inside the first two td elements, so the name and type columns, not added.

Thanks.

How about something like this?

function escapeRegex(value) {
    return value.replace(/[\-\[\]{}()*+?.,\\\^$|#\s]/g, "\\$&");
}

$(function() {
    $("#search-items").bind("keyup paste", function() {
        var searchText = $("#search-items").val(),
            regex = new RegExp(escapeRegex(searchText), "gi"),
            $items = $(".item").show();

        if (searchText) {
            $items.each(function() {
                var $tds = $("td", this).slice(0, 2), // only the first two columns
                    text = $tds.text();

                if (text.search(regex) === -1) {
                    $(this).hide();
                }

            });
        }
    });
});​

Example: http://jsfiddle.net/Pc7Nk/1/

The escapeRegex function was shamelessly stolen from jQueryUI autocomplete's source code.

The following code will try and match the values as you type them to either column1 or 2.

$("#search").on("keyup paste", function() {
    var value = $(this).val().toUpperCase();
    var $rows = $("table tr");

    if(value === ''){
        $rows.show();
        return false;
    }

    $rows.each(function(index) {
        if (index !== 0) {

            $row = $(this);

            var column1 = $row.find("td:first a").html().toUpperCase();
            var column2 = $row.find("td").eq(1).text().toUpperCase();

            if ((column1.indexOf(value) > -1) || (column2.indexOf(value) > -1)) {
                $row.show();
            }
            else {
                $row.hide();
            }
        }
    });
});​

DEMO - Searching your table by column 1 and 2 values individually (not added)

I'm sure there is a much more efficient way of writing it but this should get you started.

Going row by row, find the first td (you can also add n number of td elements you want to match against if you like. .text() will return a string, using the string object .search method, you are returning the index of the first match, -1 is returned if there was no match, so we hide the row.

$("#search-items").bind("keyup paste", function() {
    var searchText = $("#search-items").val(); 

    $(".item").each(function() {
         var $this = $(this)
         if ($this.find('td:first-child').text().search(searchText) === -1) {
             $this.hide()
         }
    });
});
