.children()将获取匹配元素集中每个元素的子元素，可选择由选择器进行过滤。

使用find()方法获取当前匹配元素集中每个元素的后代，由选择器，jQuery对象或元素过滤。

$(document).ready(function () {

    $('.play-youtube').click(function (e) {
        e.preventDefault();
        var URL = $(this).attr('href');
        var htm = '<iframe width="438" height="250" src="http://www.youtube.com/embed/' + URL + '" frameborder="0" allowfullscreen="1" ></iframe>';


        $(".active-video-title").html($(this).find(".title").html());
         $(".active-video-date").html($(this).find(".date").html());
        $(".active-video-title").html($(this).find(".featured-title").html());
        $(".active-video-date").html($(this).find(".featured-date").html());
        return false;
    });
});
