Question

我正在使用“Mastering XPages - Second Editon”（chap11e2b.nsf）一书中的示例数据库，他们在这里创建了一个扩展的富文本编辑器。有一个托管bean用于获取/设置字段值。在示例中，自定义控件将其用作

<mxpd2:inputRichText id="inputRichTextExtended"
            style="width:100%" htmlFilter="identity"
            htmlFilterIn="identity" disableModifiedFlag="false"
            htmlConversionWarning="noWarning">

            <mxpd2:this.value><![CDATA[#{rteBean['pageDocument.Body']}]]></mxpd2:this.value>
...

我需要检查一个字段，以便我知道在控件中使用哪个字段，标准的“Body”字段或“BodyHTMLMime”，以防文档有一个标志（字段称为“转换”）设置为“1”

如何在EL语言中完成，或者如何在SSJS中使用rteBean。['pageDocument.Body']？

最糟糕的情况我创建了两个控件并隐藏了对该标志进行eacocrding，但我确信没有必要在数据属性级别进行调用。

谢谢：）

编辑：

我的代码现在是这样的：

<xp:text escape="true" id="BodyFieldName">
    <xp:this.value><![CDATA[#{javascript://sessionScope.BodyFieldName = 'pageDocument.Body';
viewScope.BodyFieldName = pageDocument.getItemValueString("v2_convertedtomime") == "1" ? "pageDocument.BodyHTMLMime" : "pageDocument.Body";
viewScope.BodyFieldName;        }]]>
    </xp:this.value>
</xp:text>

<mxpd2:inputRichText id="inputRichTextExtended"
    style="width:100%" htmlFilter="identity" htmlFilterIn="identity"
    disableModifiedFlag="false" htmlConversionWarning="noWarning"
    value="#{rteBean[viewScope.BodyFieldName]}">

    <xp:this.converter>
        <xp:converter
            converterId="InputRichTextConverter">
        </xp:converter>
    </xp:this.converter>

    ...

以下是我使用此代码时遇到的错误：

Answer 1

inputRichText的值必须是EL，因为它使用rteBean的getter和setter。

计算字段名称并将其放入viewScope变量中。

在EL：

中使用viewScope变量作为字段名称

<xp:text
    escape="true"
    id="computedField1">
    <xp:this.value><![CDATA[#{javascript:
        viewScope.fieldName = document1.getItemValueString("converted") == "1" ? "document1.BodyHTMLMime" : "document1.Body1"; 
        ""}]]></xp:this.value>
</xp:text>
<xp:div themeId="container" style="width:800px">
    <mxpd2:inputRichText id="inputRichText1"
        value="#{rteBean[viewScope.fieldName]}">

XPages EL：添加条件以选择字段名称
