     * Sina股票数据接口 以大秦铁路（股票代码：601006）为例，如果要获取它的最新行情，只需访问新浪的股票数据
     * 接口：http://hq.sinajs.cn/list=sh601006这个url会返回一串文本，例如：
     * 
     * var hq_str_sh601006="大秦铁路, 27.55, 27.25, 26.91, 27.55, 26.20, 26.91,
     * 26.92, 22114263, 589824680, 4695, 26.91, 57590, 26.90, 14700, 26.89,
     * 14300, 26.88, 15100, 26.87, 3100, 26.92, 8900, 26.93, 14230, 26.94,
     * 25150, 26.95, 15220, 26.96, 2008-01-11, 15:05:32";
     * 
     * 这个字符串由许多数据拼接在一起，不同含义的数据用逗号隔开了，按照程序员的思路，顺序号从0开始。 0：”大秦铁路”，股票名字；
     * 1：”27.55″，今日开盘价； 2：”27.25″，昨日收盘价； 3：”26.91″，当前价格； 4：”27.55″，今日最高价；
     * 5：”26.20″，今日最低价； 6：”26.91″，竞买价，即“买一”报价； 7：”26.92″，竞卖价，即“卖一”报价；
     * 8：”22114263″，成交的股票数，由于股票交易以一百股为基本单位，所以在使用时，通常把该值除以一百；
     * 9：”589824680″，成交金额，单位为“元”，为了一目了然，通常以“万元”为成交金额的单位，所以通常把该值除以一万；
     * 10：”4695″，“买一”申请4695股，即47手； 11：”26.91″，“买一”报价； 12：”57590″，“买二”
     * 13：”26.90″，“买二” 14：”14700″，“买三” 15：”26.89″，“买三” 16：”14300″，“买四”
     * 17：”26.88″，“买四” 18：”15100″，“买五” 19：”26.87″，“买五”
     * 20：”3100″，“卖一”申报3100股，即31手； 21：”26.92″，“卖一”报价 (22, 23), (24, 25),
     * (26,27), (28, 29)分别为“卖二”至“卖四的情况” 30：”2008-01-11″，日期； 31：”15:05:32″，时间；
