jquery remove duplicate

I have table which is bound dynamically:

    <table id="test">
    <tr>
    <td>test1<td>
    </tr>
    <tr>
    <td>test2<td>
    </tr>
    <tr>
    <td>test1<td>
    </tr>
    <tr>
    <td>test2<td>
    </tr>
    </table>

I want to remove duplicate table rows, producing a result like this.

    <table id="test">
    <tr>
    <td>test1<td>
    </tr>
    <tr>
    <td>test2<td>
    </tr>
    </table>

sol

var seen = {};
$('table tr').each(function() {
    var txt = $(this).text();
    if (seen[txt])
        $(this).remove();
    else
        seen[txt] = true;
});
