Question

我想将p：commandButton中显示的值存储在辅助bean中的变量中。这是我的命令按钮。

<p:commandButton value="#{rec.UTILITY_BILL_UPLOAD}" actionListener="#{pavReqAssign.DownloadFile}" onclick="PrimeFaces.monitorDownload(start, stop);" icon="ui-icon-arrowthick-1-s" >
<p:fileDownload value="#{pavReqAssign.file}" />
</p:commandButton>

和我想要存储值的变量（即“＃{rec.UTILITY_BILL_UPLOAD}”），是：

string fileNameDL;

Answer 1

尝试此操作，假设在托管bean fileNameDL中声明了属性pavReqAssign：

<p:commandButton value="#{rec.UTILITY_BILL_UPLOAD}" actionListener="#{pavReqAssign.DownloadFile}" onclick="PrimeFaces.monitorDownload(start, stop);" icon="ui-icon-arrowthick-1-s" >
    <f:setPropertyActionListener target="#{pavReqAssign.fileNameDL}" value="#{rec.UTILITY_BILL_UPLOAD}" />
    <p:fileDownload value="#{pavReqAssign.file}" />
</p:commandButton>

如何在p：commandButton中存储值？
