动态数据绑定? [英] Dynamic Data Binding?

问题描述

我的 Notes 文档中有几个字段

I have several fields on my Notes Document

字段A_1字段A_2字段A_3字段A_4

FieldA_1 FieldA_2 FieldA_3 FieldA_4

字段B_1场B_2场B_3字段B_4

FieldB_1 FieldB_2 FieldB_3 FieldB_4

在复合控件上我有 2 个编辑框场A字段B

On a composite control I have 2 edit boxes FieldA FieldB

我有一个 CompositeData.ATM_NUM 定义了一个自定义控件，它是一个下拉列表，值为 1、2、3、4.

I have a compositeData.ATM_NUM defined a custom control that is a drop down list with the values 1,2,3,4.

如何使用可用的复合数据将控件上的编辑框绑定到相应的文档字段?

How do I bind the edit boxes on my control to their corresponding document fields using the composite data available?

例如，我想做这样的事情:"FieldA_"+复合数据.ATM_NUM.

For example, I wanted to do something like: "FieldA_"+ compositeData.ATM_NUM.

我在此线程中尝试了 javascript 解决方案:

I tried the javascript solution in this thread:

绑定编辑以编程方式将自定义控件中的框添加到表单字段

但它似乎不起作用.

推荐答案

尝试以下值作为例如字段 A:

Try the following as value for e.g. field A:

<xp:inputText value="#{document['FieldA'+compositeData.ATM_NUM]}" />

您还可以扩展自定义控件的属性以包含整个字段名称(从而将例如FieldA_1"传输到自定义控件).那么您应该能够执行以下操作:

You could also extend the property of the custom control to include the whole field name (and thereby transfer e.g. "FieldA_1" to the custom control). Then you should be able to do the following:

<xp:inputText value="#{document[compositeData.fieldName]}" />
