刷新< ui:define>在jsf中 [英] refresh a <ui:define> in jsf

问题描述

我的jsf中有一个这样的"ui:define":

I have a "ui:define" in my jsf like this :

<ui:define name="javaScript">

<script type="text/javascript"> #{PendingTree.buildHistoryForTree} </script>
<script type="text/javascript"> #{PendingTree.buildDescriptionForTree} </script>

<script type="text/javascript">
  .
  .
  .
</script>
</ui:define>

如果某些事件已经完成，我想刷新ui:define； 我该怎么做?

I want to refresh the ui:define if some event have been done; how can I do this job ?

推荐答案

您只能ajax更新JSF组件.

You can only ajax-update JSF components.

将其包装在JSF组件中(前提是您将其放置在<h:body>的底部).

Wrap it in a JSF component (provided that you placed this inside (bottom of) <h:body>).

<h:panelGroup id="scripts" layout="block">
    <ui:define name="scripts">
        <h:outputScript>
            #{bean.script1}
            #{bean.script2}
            .
            .
            .
        </h:outputScript>
    </ui:define>
</h:panelGroup>

然后您可以像下面这样引用它:

Then you can reference it like below:

<f:ajax ... render=":scripts" />
