如何制作水平/垂直滚动动画？

Question

This my current code. 这是我当前的代码。 This loads all the comments, and show the comments within <p> as the time of video goes by. 这将加载所有评论，并在视频播放时在<p>内显示评论。

The style newsticker is square with border line. newsticker样式是带有边框的正方形。

I want to show the comment in it, and slides-in, then slides-out. 我想在其中显示评论，然后先滑入，然后滑出。 Just like this here http://spreadthesource.com/sandbox/featurify/ 就像这里http://spreadthesource.com/sandbox/featurify/

How can I make it possible? 我怎样才能实现呢？
The point is refreshing content of <p> every seconds with onPlay of media. 关键是利用媒体的onPlay每秒刷新<p>内容。
So loaded comment has to slide-in, and stay there for 5 seconds, and slides out to disappear. 因此，已加载的评论必须滑入并停留在那里5秒钟，然后滑出以消失。

I made DEMO with jsfiddle. 我用jsfiddle制作了DEMO 。

Anyone can show me with code please. 任何人都可以给我看代码。

Javascript Java脚本

jQuery(document).ready(function () {

    $('#video').on('timeupdate',function(e){
        showComments(this.currentTime);
    });

}); 
var comments = [{'time':'10','message':'hello! 10 secs has past'},{'time':'10','message':'hello! 10-2 secs has past'},{'time':'5','message':'hello! 5 secs has past'},{'time':'30','message':'hello! 30 secs has past'}];


function showComments(time){
    var comments = findComments(time);
    $.each(comments,function(i,comment){
        $('p#newsticker').text(comment.message);

        // Show for 5 seconds, then hide the `p` element.
        $('p#newsticker').show().delay(2000).fadeOut();
    });
}

function findComments(time){
    return $.grep(comments, function(item){
      return item.time == time.toFixed();
    });
}

HTML HTML

<body>
    <div class="newsticker"> 
        <p id="newsticker"></p>
    </div>
    <br />
    <br />
    <video id="video" controls="controls" autoplay="autoplay" name="media"><source src="http://media.w3.org/2010/05/sintel/trailer.mp4" type="video/mp4"></video>
</body>

CSS CSS

div.newsticker{
    border:1px solid #666666;
    width:400px;
    height:50px;
}

jQuery(document).ready(function () {
    var counter=5;
    $('#video').on('timeupdate',function(e){
        if(this.currentTime > counter){
            showComments(this.currentTime);
            counter+=5; // for updating the comment every after 5 seconds.
        }    
    });

}); 
var comments = [{'time':'10','message':'hello! 10 secs has past'},{'time':'15','message':'hello! 15 secs has past'},{'time':'5','message':'hello! 5 secs has past'},{'time':'20','message':'hello! 20 secs has past'}];


function showComments(time){
    var comments = findComments(time);
    $.each(comments,function(i,comment){
        $('.newsticker p').animate({"marginLeft":"400px","opacity":".0"}, 600).fadeOut(100);
        $('.newsticker').append("<p style='margin-left:400px;opacity:0'>"+comment.message+"</p>");
        $('.newsticker p').animate({"marginLeft":"0px","opacity":"1"}, 600);
    });
}

function findComments(time){
    return $.grep(comments, function(item){
      return item.time == time.toFixed();
    });
}
