<script language="javascript" type="text/javascript">
    var Num ;
    var conn="provider=Sqloledb;server=.;uid=sa;pwd=sa;database=ZhuFTest";
    var rs=new ActiveXObject("ADODB.recordset");
    var sql="select GoodsID,GoodsName,Price,Num from Goods";  
    rs.Open(sql,conn);
    function ConnectionSql(){ 
        rs.Open(sql,conn,2,2);
        document.getElementById("GID").value=rs("GoodsID");
        document.getElementById("GName").value=rs("GoodsName");
        document.getElementById("Pri").value=rs("Price");
        document.getElementById("Num").value=rs("Num"); 
    }
    function Next(){//'下一条'
           rs.MoveNext();
           if(rs.EOF == true){
              rs.MovePrevious();
              alert("最后一条记录！"); 
           return;
            }
               else{

    function First(){//'第一条'
        rs.MoveFirst();

        document.getElementById("Num").value=rs("Num");
    }
    
    function Per(){//'上一条'
        rs.MovePrevious();
        if(rs.BOF == true){
           rs.MoveNext();
           alert("第一条记录！"); 
           return;
        }
        else {
        document.getElementById("GID").value=rs("GoodsID");
        document.getElementById("GName").value=rs("GoodsName");
        document.getElementById("Pri").value=rs("Price");
        document.getElementById("Num").value=rs("Num");
        }
    }
rs.Close();
</script>
</head>
<body onload="return ConnectionSql();">
<table>
<tr><td>商品编号：</td><td><input type="text" id="GID" /></td></tr>
<tr><td>商品名称：</td><td><input type="text" id="GName" /></td></tr>
<tr><td>商品价格：</td><td><input type="text" id="Pri" /></td></tr>
<tr><td>商品数量：</td><td><input type="text" id="Num" /></td></tr>
</table>
<input type="button" id="Next" value="下一条" onclick="return Next();"/>
<input type="button" id="First" value="First" onclick="return First();"/>
<input type="button" id="Button1" value="Last" onclick="return Last();"/>
<input type="button" id="Per" value="上一条" onclick="return Per();"/>
</body>
</html>这是操作ACCESS ，我想都差不多吧，个人觉得用JS操作数据库意义不大
