jQuery - find table row containing table cell containing specific text

Question

I need to get a tr element which contains a td element which contains specific text. The td will contain that text and only that text

Answer 1

$(function(){
    var search = 'foo';
    $("table tr td").filter(function() {
        return $(this).text() == search;
    }).parent('tr').css('color','red');
});

Will turn the text red for rows which have a cell whose text is 'foo'.
