推荐答案

我们使用onbeforeunload挂钩在弹出窗口时从弹出窗口调用函数

<script>
        window.onbeforeunload = function() { 
            document.forms["showpdf"].elements["hiddenBtn"].click();
            }
    </script>
    <h:body>
        <f:view>
            <h:form id="showpdf">
                <iframe src="#{docProd.url}" width="100%" height="100%">     </iframe>
                <div align="center"><p:commandButton id="hiddenBtn"
                    onclick="#{docProd.resetUrl}" style="display:none"   /></div>
            </h:form>
        </f:view>
    </h:body>
    </ui:composition>
