Liferay aui:具有多个aui:按钮的表单

我正试图开发一个有三个aui:按钮的aui:表单，这样

<portlet:actionURL name="generateRule" var="generateRuleURL"/>
<portlet:actionURL name="generateRuleAnd" var="generateRuleAndURL"/>
<portlet:actionURL name="generateRuleOr" var="generateRuleOrURL"/>

<aui:form action="<%= generateRuleURL.toString() %>" method="post">
<aui:fieldset column="false">
<aui:select name="FirstRuleElement" >
<aui:option value="Age">
<liferay-ui:message key="Age" />
</aui:option>
<aui:option value="Country">
<liferay-ui:message key="Country" />
</aui:option>
<aui:option value="Direction">
<liferay-ui:message key="Direction" />
</aui:option>
</aui:select>
<aui:select name="FirstRuleAttribute" >
<aui:option value="Age">
<liferay-ui:message key="Age" />
</aui:option>
<aui:option value="Country">
<liferay-ui:message key="Country" />
</aui:option>
<aui:option value="Direction">
<liferay-ui:message key="Direction" />
</aui:option>
</aui:select>
</aui:fieldset>
<aui:fieldset column="false">
<aui:button-row>
<aui:button type="submit" value="End" />

<aui:button type="submit" value="And"
onClick="<%= generateRuleAndURL.toString()%>" />

<aui:button type="submit" value="Or"
onClick="<%= generateRuleOrURL.toString()%>" />
</aui:button-row>
</aui:fieldset>
</aui:form>

正在使用此函数检索数据

request.getParameter("FirstRuleElement")

但通过单击和或按钮，我无法获得表单的请求参数

你知道我怎么解决这个问题吗

谢谢,， Oriol

而不是这个

<aui:button type="submit" value="And"
onClick="<%= generateRuleAndURL.toString()%>" />

<aui:button type="submit" value="Or"
onClick="<%= generateRuleOrURL.toString()%>" />

，您可以使用下面的javascript

<aui:button type="submit" value="And"
onClick="javascript:submitTheForm('<%= generateRuleAndURL.toString()%>')" />
<aui:button type="submit" value="Or"
onClick="javascript:submitTheForm('<%=generateRuleOrURL.toString()%>')" />

<script>
function submitTheForm(url){
    document.forms['<portlet:namespace/>myform'].action=url;
    document.forms['<portlet:namespace/>myform'].submit();
}
</script>

函数提交表单（url）{
document.forms['myform'].action=url；
document.forms['myform'].submit（）；
}

将name属性作为aui:form的myForm

这是我在docroot文件夹下的view.jsp中的代码

<portlet:defineObjects />

<c:choose>
    <c:when test="<%= themeDisplay.isSignedIn() %>">
        <aui:form action="<%= generateRuleURL.toString() %>" method="post">
            <aui:fieldset column="false">
            <aui:select name="FirstRuleElement" >
                <aui:option value="Age">
                    <liferay-ui:message key="Age" />
                </aui:option>
                <aui:option value="Country">
                    <liferay-ui:message key="Country" />
                </aui:option>
                <aui:option value="Direction">

能否尝试将“onClick=”“/>”替换为“href=”并将“type=“submit”替换为“type=“button””。如果不起作用，request.getParameter参数为null。AUI button onClick：单击按钮时要执行的javascript代码。如果此属性以http://开头，则当用户单击该按钮时，该按钮会将您带到该页面。现在，由于您已经在onclick中提供了url，它将访问该url[从http://]开始，但表单不会被提交。你可以编写一些在onclick上调用的js代码，在表单中设置所需的url并提交。你能给我看一个js的示例吗？点击其中一个按钮，我得到这些url。。。我认为document.forms生成的不是一个好的文档。我正在一个名为view.jsp的文件中实现表单
