Request.ServerVariables("HTTP_REFERER")
字符串处理下strLength = document.referrer.length
strUrl = document.referrer.substring( 7 , strLength )
strUrl = strUrl.substring( 0 , strUrl . indexOf("/") )
document.write( strUrl )
函数说明
str.Length -------------------返回字符串总长度
str.substring( start_Index, stop_Index ) -----------------截取指定区间字符串
str.indexOf( child_str ) -------------------------返回子字符串第一次在str中出现的位置的
