近期Post了不少Javascript文章，還是收到不少支持，你們的回復是我寫下去的動力，謝謝你們！

剛剛研究了一下新浪的財經板塊，其中對股票數據的處理真的是跟我的MVC模式的文章不謀而合啊。我順手寫了2段代碼，大家看看。

Stock.html <!DOCTYPE?HTML?PUBLIC?"-//W3C//DTD?HTML?4.0?Transitional//EN">

<head>
????<title>Truly's?stock</title>
????<script?src=data.js></script>
????<style>
/*?change_color?*/
.incolor{color:#FF0000;}
.decolor{color:#008000;}
#itemTickettime
{
????font-size:12px;
}
span,div{font-size:12px;}
????</style>
</head>

呵呵，寫的很簡單就不往首頁放了。大家慢慢看，玩股票的兄弟們祝你們都賺到錢，不玩股票的就多研究研究技術。這里下載源碼。

enjoy code！
