    /// 一些常用的Js調(diào)用
    /// 添加新版說(shuō)明：由于舊版普遍采用Response.Write(string msg)的方式輸出js腳本，這種
    /// 方式輸出的js腳本會(huì)在html元素的<html></html>標(biāo)簽之外，破壞了整個(gè)xhtml的結(jié)構(gòu),
    /// 而新版本則采用ClientScript.RegisterStartupScript(string msg)的方式輸出，不會(huì)改變xhtml的結(jié)構(gòu),
    /// 不會(huì)影響執(zhí)行效果。
    /// 為了向下兼容，所以新版本采用了重載的方式，新版本中要求一個(gè)System.Web.UI.Page類的實(shí)例。
