JS 将数据库取出的数据封装成对象存入数组，取不出

JScript code

var dataSource = "d:/share/booksystem.accdb";var conn;var rs;//返回ResultSet对象function getResultSet(){    conn=new ActiveXObject("Adodb.Connection");    rs=new ActiveXObject("Adodb.Recordset");    conn.ConnectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+dataSource                          +";Persist Security Info=False;"+"";                              conn.open();    rs.LockType=rs.CursorType=1;    rs.ActiveConnection=conn;    return rs;}//定义Book类function Book(name,time,memo,num){    this.name = name;    this.time = time;    this.num = num;    this.memo = memo;        this.getBK_Name = function(){        return this.name;        }        this.getBK_Time = function(){        return this.time;        }        this.getBK_Num = function(){        return this.num;        }        this.getBK_Memo = function(){        return this.memo;        }}function queryBook(){    var bookArray = new Array();    rs = getResultSet();    rs.Source="select * from book";    rs.open();    while(!rs.eof){      var b = new Book(rs('bk_name'),rs('bk_dlv_time'),rs('bk_dlv_num'),rs('bk_dlv_comment'));      bookArray.push(b);           rs.moveNext();    }        alert(bookArray.length);    var elm = bookArray[0];    alert(elm instanceof Book);    alert(elm.getBK_Name());   //本行报错：BOF 或 EOF 中有一个是“真”，                       //或者当前的记录已被删除，所需的操 作要求一个当前的记录。

JScript code

var b = new Book(   String(rs('bk_name')),   String(rs('bk_dlv_time')),   String(rs('bk_dlv_num')),   String(rs('bk_dlv_comment')));
