[英]Render multiple components with f:ajax
The wrong codes are: 错误的代码是:
<h:form id="search_form">
<h:commandButton class="button" value="View" action="#{InfoBean.search}">
<f:ajax execute="search_form" render="linear1"></f:ajax>
<f:ajax execute="search_form" render="linear2"></f:ajax>
</h:commandButton>
<p:lineChart id="linear1" value="#{InfoBean.linearModel1}" legendPosition="e"/>
<p:lineChart id="linear2" value="#{InfoBean.linearModel2}" legendPosition="e"/>
</h:form>
What I want to do is when I click on the commandButton
, I want to refresh those two charts. 我要做的是单击commandButton
,我想刷新这两个图表。 But now I used two <ajax>
tags, of which the second doesn't work. 但是现在我使用了两个<ajax>
标签,其中第二个不起作用。
So how can I use ajax to render two charts? 那么如何使用Ajax渲染两个图表呢?
You can render multiple components with single f:ajax
. 您可以使用单个f:ajax
渲染多个组件。 Just make sure all individual components you want to update have an id
. 只需确保要更新的所有单个组件都具有一个id
。 In your sample it would be something like: 在您的示例中,它将类似于:
<f:ajax execute="search_form" render="linear1 linear2"/>
Where the IDs need to be separated by just whitespace like linear1 linear2
and not commaseparated like linear1, linear2
(that works only in p:ajax
). ID仅需由空格分隔,例如linear1 linear2
而不能像linear1, linear2
和linear2一样linear1, linear2
(仅在p:ajax
)。

对于a4j jsf,请使用',': <a4j:support event="onchange" reRender="parent,child1,child2" />
