如何在 JSF 2.0 中将节点值作为复合组件中的属性传递

我正在开发一个 JSF 2.0 复合组件。我正在尝试创建一个框组件，将所需的 HTML 设置为属性。

有些事情就像......

<composite:interface>
    <composite:attribute name="value" />
</composite:interface>
<composite:implementation>
    <table cellpadding="0" cellspacing="0" border="1" width="100%">
        <tr>
            <td></td>
            <td>#{cc.attrs.value}</td>
            <td></td>
        </tr>
    </table>
</composite:implementation>

当我想使用这个组件并将所需的 HTML 传递给属性“value”时，就像这样：

<someDir:boxComp>Hello</someDir:boxComp>

“Hello”不被视为属性值。我如何使节点值作为属性值？

原文

I am developing a JSF 2.0 composite component. I am trying to create a box component to which my required HTML will be set as attribute.

Some thing like..

<composite:interface>
    <composite:attribute name="value" />
</composite:interface>
<composite:implementation>
    <table cellpadding="0" cellspacing="0" border="1" width="100%">
        <tr>
            <td></td>
            <td>#{cc.attrs.value}</td>
            <td></td>
        </tr>
    </table>
</composite:implementation>

When I want to use this component and pass the required HTML to the attribute "value", like so:

<someDir:boxComp>Hello</someDir:boxComp>

the "Hello" is not taken as attribute value.
How i can make the node value as an attribute value.?

您没有将其作为标签属性传递。您只需将其作为标签主体中的子项传递即可。在这种情况下，您需要使用插入它。因此，

<td>#{cc.attrs.value}</td>

定义

<td><composite:insertChildren /></td>

如果您实际上想使用#{cc.attrs.value}，那么您应该它从一开始就是一个真实标签属性，而不是标签主体：

<someDir:boxComp value="Hello" />

You aren't passing it as tag attribute. You are just passing it as child in the tag body. In that case you need to use <composite:insertChildren /> to insert it. So, instead of

<td>#{cc.attrs.value}</td>

you should be doing

<td><composite:insertChildren /></td>

Or if you actually want to use #{cc.attrs.value}, then you should be defining it as a real tag attribute from the beginning on instead of as tag body:
