在窗口卸载时从javascript调用a4j：commandButton

问题描述

我无法调用 a4j：commandButton 点击窗口卸载。我的jsf代码在这里

I am not able to call a4j:commandButton click on window unload. my jsf code is here

第一个 javascript 其中我有窗口卸载方法，我已调用按钮单击该功能。

1st the javascript in which i have window unload method and i have called button click in that function.

<script type="text/javascript">
    window.onbeforeunload = function() {
        document.getElementById('pForm:closeTime').click();
    }
</script>

第二个我隐藏了 a4j：commandButton in正文

2nd i have hidden a4j:commandButton in body

<h:form id="pForm">
<a4j:commandButton id="closeTime" value="" action="#{controller.update}" oncomplete="javascript:window.close()" style="visibility:hidden;display:none" </a4j:commandButton>
</h:form>

当窗口关闭时，此控制器未被调用。请帮帮我!!!

when window is closed this controller is not getting called. Help me out in this !!!

推荐答案

使用 jsFunction 为此：

<script type="text/javascript">
    window.onbeforeunload = function() {
        closeTime();
    }
</script>

<h:form id="pForm">
    <a4j:jsFunction name="closeTime"
                    action="#{controller.update}"
                    oncomplete="window.close()"/>
</h:form>
