JavaScript可以使用ASP创建的ADO记录集吗？ [英] Can ADO Recordsets Created By ASP Be Used By JavaScript?
问题描述
您好，
我的ASP代码在服务器上创建了一个ADO记录集对象。
稍后在同一页面上，我有一个我使用的javascript代码段
根据另一个
下拉框中的选项动态填充下拉框。这个javascript（或服务器端的等价物）可以访问
记录集对象吗？

您好，
我的问题很混乱，因为我自己有点困惑。我不是在客户端使用ADO的
。 ADO连接和记录集通过ASP在服务器上实例化
。我的问题是，服务器端的Javascript可以使用通过ASP代码在同一页面上创建的
a服务器端对象吗？
或服务器端Javascript必须实例化自己独立的
连接和记录集对象？

当客户端Javascript运行时，所有ASP代码 - 无论是
VBScript，Javascript，或另一种语言 - 已经完成，不再是
存在。既然如此，客户端Javascript就无法使用任何ASP对象。

Hello,
My ASP code creates an ADO recordset object on the server.
Later on the same page, I have a javascript code snippet that I use to
dynamically populate a drop-down box based on choices made in another
drop-down box. Can this javascript (or a server-side equivalent) access the
recordset object?

Only if it is passed to the client-side code. I tend to avoid trying to use
ADO on the client, preferring to use XML, but here''s one way to do it (this
example uses vbscript in the client-side script but it can easily be
rewritten to use jscript instead):

Hi,
My question was confusing because I myself am a little confused. I am not
using ADO on the client. The ADO connection and recordset are instantiated
on the server through ASP. My question is, can a server-side Javascript use
a server-side object that was created earlier on the same page by ASP code?
Or does the server-side Javascript have to instantiate its own separate
connection and recordset objects?

By the time client-side Javascript runs, all ASP code - whether
VBScript, Javascript, or another language - has finished and no longer
exists. That being the case, there''s no way client-side Javascript can
use any ASP object.
