alfresco WCM
在表單中自定義下拉框
?
alfresco
中使用WCM創建content的時候，如何在表單中使用自定義下拉框。
?
假設有一個webform，名稱為news，使用news.xsd。我們知道xsd文件可以使用:
<
xs:include
schemaLocation
="
/select_list_choices.xsd
"/>
?
include
一個xsd，
select_list_choices.xsd
代碼如下
(
注意,下面的下拉框選擇項比較少時,比如5個可能不會顯示為下拉框,而是顯示為radio button):
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:alf="http://www.alfresco.org" elementFormDefault="qualified">
??? <xs:simpleType name="
select_list_choices
">
??????? <xs:restriction base="xs:string">
??????????? <xs:enumeration value="channel01">
??????????????? <xs:annotation>
??????????????????? <xs:appinfo>
??????????????????????? <alf:label>
財經新聞</alf:label>
??????????????????? </xs:appinfo>
??????????????? </xs:annotation>
??????????? </xs:enumeration>
??????????? <xs:enumeration value="channel02">
??????????????? <xs:annotation>
??????????????????? <xs:appinfo>
??????????????????????? <alf:label>
娛樂新聞</alf:label>
??????????????????? </xs:appinfo>
??????????????? </xs:annotation>
??????????? </xs:enumeration>??????????
??????????? <xs:enumeration value="channel03">
??????????????? <xs:annotation>
??????????????????? <xs:appinfo>
??????????????????????? <alf:label>
體育新聞</alf:label>
??????????????????? </xs:appinfo>
??????????????? </xs:annotation>
??????????? </xs:enumeration>??????????
??????? </xs:restriction>
??? </xs:simpleType>
</xs:schema>
?
上面的
下拉框是靜態的，要想自定義，
則可以在news.xsd中include一個jsp，在jsp中包含所需要的xsd代碼。
?
現在我們自定義一個下拉框，創建一個新的webform，例如名稱為channel-list，使用channel-list.xsd：
<?xml version="1.0"?>
<
xs:schema
xmlns:xs
="
http://www.w3.org/2001/XMLSchema
"
xmlns:cm
="
http://www.lively.com/alfresco/cm
"
targetNamespace
="
http://www.lively.com/alfresco/cm
"
elementFormDefault
="
qualified
">
???
<
xs:element
name
="
select_list
">
???????
<
xs:complexType
>
???????????
<
xs:sequence
>
???????????????
<
xs:element
name
="
options
"
maxOccurs
="
unbounded
">
???????????????????
<
xs:complexType
>
???????????????????????
<
xs:sequence
>
???????????????????????????
<
xs:element
name
="
value
"
type
="
xs:normalizedString
"/>
???????????????????????????
<
xs:element
name
="
label
"
type
="
xs:normalizedString
"/>
???????????????????????????
<
xs:element
name
="
description
"
type
="
xs:normalizedString
"/>
???????
???????????????
</
xs:sequence
>
???????????????????
</
xs:complexType
>
???????????????
</
xs:element
>
???????????
</
xs:sequence
>
???????
</
xs:complexType
>
???
</
xs:element
>
</
xs:schema
>
?
?
使用這個webform創建content，比如創建在
/content/news
目錄下，這些創建的數據就是下拉框中使用的內容，如上所示，下拉框使用value/label/description三個元素。則可以使用一個get_channel_list.jsp來取得這些創建的下拉框列表：
<
jsp:root
version
="
1.2

上面的cm標簽是我們自己定義的，可以參看附件（注意：可以在http://forge.alfresco.com/projects/wsf/上下載wsf1.5最新源碼）。
?
最后，在xsd中引入這個get_channel_list.jsp：
<
xs:include
schemaLocation
="
/
get_channel_list.jsp
"/>
……
<
xs:element
name
="
channel
"
type
="
news:
select_list_choices
"/>
……
?
這樣一個自定義的下拉框就可以實現了。
