用javascript+jquery写的一个定时器,定时修改文章标题。
代码如下:


<!DOCTYPE html>
<html>
<head>
<title>TODO supply a title</title>
<meta charset="GB2312">
<meta name="viewport" content="width=device-width">
</head>

<body>
<div>
<ul id="jokeTitle">
<li class="line">Test Line One</li>
<li class="line">Test Line Two</li>
<li class="line">Test Line Three</li>
</ul>
</div>
<script type="text/javascript" src="ie/js/jquery-1.9.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){

var changeJokeTitle = {
line:3, //笑话的总行数
timeSpan:1850, //时间间隔(毫秒)
interval:'', //定时器句柄,以便于停止
showLineFlag:0, //标志,
change:function(){

var currentLine = (++changeJokeTitle.showLineFlag)%(changeJokeTitle.line);

$('#jokeTitle li:eq('+currentLine+')').show();
$('#jokeTitle li:not(:eq('+currentLine+'))').hide();
},
run:function(){
$('#jokeTitle li:eq(0)').show();
$('#jokeTitle li:not(:eq(0))').hide();
changeJokeTitle.interval = setInterval(changeJokeTitle.change, changeJokeTitle.timeSpan);
}
};

changeJokeTitle.run();

});
</script>
</body>

</html>
