javascript + jquery實現定時修改文章標題_javascript技巧

用javascript+jquery寫的一個定時器，定時修改文章標題。

複製代碼 代碼如下:

<!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, //笑話的總行數
timeSpan:1850, //時間間隔（毫秒）
interval:'', //定時器控制代碼，以便於停止
showLineFlag:0, //標誌，
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>
