问题描述
我正在使用 Struts 创建一个数据库记录编辑表单.
I'm creating a database record edit form using Struts.
<s:select id="status" name="newRecord.status" list="statusTypes" listKey="id" listValue="description" label="Status:" value="" /><br />
示例列表:
Status' list:
1 Open
2 Closed
3 Pending
我想在状态字段上设置一个默认值作为存储在 record.status
中的当前状态,其中包含字符串表示,例如打开"
.
I want to set a default value on the status field as the current status which is stored in record.status
which contains the string representation e.g. "Open"
.
如果我设置 value="%{record.status}
它不起作用,因为这不是任何列表键.当我只有字符串表示形式时,有没有办法设置这个值合作吗?
If I set value="%{record.status}
it doesn't work because that's not any list key. Is there a way I can set this value when I only have the string representation to work with?
或者我应该将 record.status
重新设计为具有 ID 和 String
的对象吗?
Or should I redesign record.status
to be an object with ID and String
?
推荐答案
您应该初始化 newRecord.status
的值,该值应该是包含列表键值的单独属性.然后只需设置默认的 value="%{record.status}"
.当我说属性时,我指的是可通过 OGNL 访问的 bean 属性.
You should initialize the value of the newRecord.status
that should be a separate property that contains the list key value. Then simply set the default value="%{record.status}"
. When I said the property I mean the bean property that is accessible via OGNL.
