给定以下primefaces数据
<p:dataTable value="#{cc.attributes.playerCollection}" var="player"
widgetVar="playerWidgetTable" emptyMessage="#{uimsg.ui_not_recordsfound}">
<!-- filter event handler -->
<p:ajax event="filter" listener="#{cc.attributes.viewBean.listenFilter}" update="@this"/>
<!-- Player first name -->
<p:column id="firstnameColumn" headerText="#{uimsg.firstname}"
filterBy="#{player.firstName}" filterMatchMode="contains">
<h:outputText value="#{player.firstName}" />
</p:column>
</p:dataTable>
某人如何获得(在服务器端)用户在过滤器文本列中给出的过滤器“文本”值？
我试着用“listenFilter”监听过滤事件:
@ManagedBean
@ViewScoped
public class PlayerListBean implements Serializable {
......
public void listenFilter(FilterEvent event) {
// update datasource
Map<String, String> tempString = event.getFilters();
System.out.println("size filter: "+ tempString.size());
for (String key : tempString.keySet()) {
System.out.println("key: " + key + " \t values: "
+ tempString.get(key));
}
}
}
但我无法用它开始。 他们还有其他选择吗？喜欢将 DataTable 作为绑定(bind)组件使用，否则？
谢谢
最佳答案
这对我来说很好......
public void listenFilter(FilterEvent event) {
DataTable table = (DataTable) event.getSource();
Map<String, String> filters = table.getFilters();
//grab the value from the required map key (somePropertyName if your filterBy
looks like filterBy="#{myBean.somePropertyName}") ...
}
