[英]Assign a unique client ID to each <rich:dataTable /> row?
I'm relatively new to working with the UI in Seam, so I'm hoping there is something simple I can replace the three instances of UNIQUE_ID
with in the following example. 我在Seam中使用UI相对较新,因此希望在以下示例中可以用一些简单的东西替换
UNIQUE_ID
的三个实例。
The goal is to have a <rich:dataTable />
wherein each row has the ability to show/hide a <rich:modalPanel />
with more details about the particular object instance. 目的是要有一个
<rich:dataTable />
其中每一行都可以显示/隐藏一个<rich:modalPanel />
其中包含有关特定对象实例的更多详细信息。
<rich:dataTable var="object" value="#{bean.myObject}">
<rich:column>
<h:outputText value="#{object.summary}" />
</rich:column>
<rich:column>
<a onclick="Richfaces.showModalPanel('UNIQUE_ID');" href="#">Show Details in ModalPanel</a>
<a4j:form>
<rich:modalPanel id="UNIQUE_ID" >
<a onclick="Richfaces.hideModalPanel('UNIQUE_ID');" href="#">Hide This ModalPanel</a>
<h:outputText value="#{object.details}" />
</rich:modalPanel>
</a4j:form>
</rich:column>
</rich:dataTable>
If I only had one link/modalPanel pair, this would obviously be trivial, but I don't know what to do within the scope of the <rich:dataTable />
's iteration. 如果我只有一对link / modalPanel对,这显然是微不足道的,但是我不知道在
<rich:dataTable />
的迭代范围内该怎么做。 Also, in case it complicates things further, the page will also contain many <rich:dataTable />
's, each implementing this behavior. 同样,如果进一步使事情复杂化,该页面还将包含许多
<rich:dataTable />
,每个都实现此行为。
Take a look at the <rich:componentControl />
tag. 看一下
<rich:componentControl />
标记。
Use attachTo to "bind" the event to display the modalPanel you wish to popup using the for attribute. 使用attachTo来“绑定”事件,以使用for属性显示要弹出的modalPanel。
Ex: 例如:
<h:outputLink id="modalPanelLink" value="#">Show Details
<rich:componentControl attachTo="modalPanelLink" for="modalPanelId" event="onclick" operation="show" />
</h:outputLink>
