我有一个<p:inputText value="#{beans.text}" />和一个<p:commandButton actionlistener="#{beans.method}" />。如何通过 inputText 中的“输入”从 Button 执行 actinoListener-Method？

感谢您的回答

出了点问题。这是代码片段->

<h:panelGrid columns="2">
<p:commandButton actionListener="#{hoursView.saveOrUpdateHour}" />
<p:commandButton actionListener="#{hoursView.onFilterChange()}" oncomplete="dlgHoursFilter.show()" immediate="true" update=":hoursFilter" />
</h:panelGrid>
</h:panelGrid>
<h:panelGrid columns="4" class="buttonContent" id="buttonView">
<p:commandButton ajax="false" actionListener="#{hoursView.showDay()}" immediate="true" update="hoursList" />
<p:commandButton  ajax="false" actionListener="#{hoursView.showWeek()}" immediate="true" update="hoursList" />
<p:commandButton  ajax="false" actionListener="#{hoursView.showMonth()}" immediate="true" update="hoursList" />
<p:commandButton  ajax="false" actionListener="#{hoursView.showAll()}" immediate="true" update="hoursList" />
</h:panelGrid>
         <h:panelGrid columns="3" id="tableGrid">
            <p:dataTable id="hoursList" value="#{hoursView.listHours}"
                var="hours" widgetVar="hoursTable" resizableColumns="true"
                emptyMessage="#{msg.noData}" rowKey="#{hours.id}"
                selection="#{hoursView.selected}" selectionMode="single">

                <p:ajax event="rowDblselect" update=":hourEditDialog"
                    listener="#{hoursView.onHourSelect}"
                    oncomplete="dlgHourEdit.show()" />

                <f:facet name="header">
                    <h:panelGrid columns="3" class="buttonContent" id="regexContent">
                        <h:outputText value="#{msg.regexHour}" />
                        <p:inputText value="#{hoursView.regex}" id="regex">
                        </p:inputText>
                        <p:commandButton icon="addButton" id="regexSave"
                            process="regexContent" actionListener="#{hoursView.regexSave}"
                            update=":editContent:hoursList,:editContent:growl,regex">
                            <p:defaultCommand target="regexSave" scope="regexContent" />
                        </p:commandButton>
                        <p:tooltip for="regexSave" value="#{msg.regexSave}"
                            showEffect="fade" hideEffect="fade" />
                    </h:panelGrid>
                </f:facet>

如果我触发“输入”事件，则将执行正则表达式保存方法。但是 saveOrUpdateHour 的方法也是....

<h:panelGrid columns="2">
<p:commandButton actionListener="#{hoursView.saveOrUpdateHour}" />
<p:commandButton actionListener="#{hoursView.onFilterChange()}" oncomplete="dlgHoursFilter.show()" immediate="true" update=":hoursFilter" />

<p:commandButton  ajax="false" actionListener="#{hoursView.showAll()}" immediate="true" update="hoursList" />
</h:panelGrid>
<h:panelGrid columns="3">
<h:outputText value="#{msg.regexHour}" />
<p:inputText value="#{hoursView.regex}" id="regex">
<p:ajax event="change" update="hoursList, growl" listener="#{hoursView.regexSave}" />
</p:inputText>
<p:commandButton  actionListener="#{hoursView.regexSave}" update="hoursList, growl" />
</h:panelGrid>

同时我已经配置了我的代码。现在文本字段和按钮在我的表格的标题中。

    <h:panelGrid columns="3" id="tableGrid">
            <p:dataTable id="hoursList" value="#{hoursView.listHours}"
                var="hours" widgetVar="hoursTable" resizableColumns="true"
                emptyMessage="#{msg.noData}" rowKey="#{hours.id}"
                selection="#{hoursView.selected}" selectionMode="single">

                <p:ajax event="rowDblselect" update=":hourEditDialog"
                    listener="#{hoursView.onHourSelect}"
                    oncomplete="dlgHourEdit.show()" />

                <f:facet name="header">
                    <h:panelGrid columns="3" class="buttonContent" id="regexContent">
                        <h:outputText value="#{msg.regexHour}" />
                        <p:inputText value="#{hoursView.regex}" id="regex">
                        </p:inputText>
                        <p:commandButton icon="addButton" id="regexSave"
                            process="regexContent" actionListener="#{hoursView.regexSave}"
                            update=":editContent:hoursList,:editContent:growl,regex">
                            <p:defaultCommand target="regexSave" scope="regexContent" />
                        </p:commandButton>
                        <p:tooltip for="regexSave" value="#{msg.regexSave}"
                            showEffect="fade" hideEffect="fade" />
                    </h:panelGrid>
                </f:facet>   ....

您可以在 jquery 的帮助下使用onkeypressand调用p:inputText按钮.click()上的return false;p:ajax for example

像这样：

<p:commandButton id="myButtonID" actionlistener="#{beans.method}" />


<p:inputText value="#{beans.text}" onkeypress="if (event.keyCode == 13) { jQuery('#myButtonID').click(); return false;}"/>

更新而不是:editContent:hoursList尝试update="tableGrid"（请参阅表包装器）或者如果您使用的是 primefaces 3.4 尝试update="hoursList"
