可收缩的面板（像Gmai收件箱面板l）。可以应用在文章、新闻评论列表中。见图效果：
js:
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { //hide message_body after the first one $(".message_list .message_body:gt(0)").hide(); //hide message li after the 5th $(".message_list li:gt(4)").hide(); //toggle message_body $(".message_head").click(function () { $(this).next(".message_body").slideToggle(500) return false; }); //collapse all messages $(".collpase_all_message").click(function () { $(".message_body").slideUp(500) return false; }); //show all messages $(".show_all_message").click(function () { $(this).hide() $(".show_recent_only").show() $(".message_list li:gt(4)").slideDown() return false; }); //show recent messages only $(".show_recent_only").click(function () { $(this).hide() $(".show_all_message").show() $(".message_list li:gt(4)").slideUp() return false; }); }); </script>
