标签: commandlink

我看到BalusC提供的这个例子:

<h:outputText value="#{bean.calendar.time}">
    <f:convertDateTime type="both" dateStyle="long" />
</h:outputText>

怎么用< h:commandLink>？

我试过了:

<h:commandLink value="#{question.creationDate.time}"
    action="#{managerBean.searchQuestion()}">
  <f:convertDateTime type="both" dateStyle="short" />
  <f:setPropertyActionListener target="#{managerBean.questionID}"
    value="#{question.ID}" />
</h:commandLink>

环境:Tomcat 6,jsf 2.0,prime faces 2.2.1,chrome explorer

我想单击左侧展开树中的"ViewDetail"链接,并显示产品的详细信息.但是下面的代码不起作用.然后我将属性ajax ="false"添加到链接,似乎工作.但位于页面左侧的"p:treeTable"也会刷新并折叠.那么我该怎么办呢:单击左侧展开的树节点上的链接,在页面的右侧显示信息,并保持左展开的树节点仍然展开.

<h:form id="BizTypeTreeTableForm" >
        <p:layout fullPage="true">
            <p:layoutUnit id="left" position="left" scrollable="true"     width="350" resizable="true" closable="false" collapsible="true" minWidth="250" >
                  <p:treeTable id="BizTypeTreeTable" value="#    {treeTableController.root}" var="treeTable">
                      <p:column>
                              <f:facet name="header">ProductName</f:facet>
                              <h:outputText value="#{treeTable.TYPENAME.value }" />
                          </p:column>
                          <p:column style="width:5%">
                              <f:facet name="header">Action</f:facet>
                              <p:commandLink value="ViewDetail" update="content"      action="#{treeTableController.showDetail}">
                              </p:commandLink>
                      </p:column>
                      </p:treeTable>
            </p:layoutUnit>
            <p:layoutUnit id="center" rendered="true" position="center"    style="text-align:left;" scrollable="true" >
                <h:outputText value="Please click the left tree node" rendered="#    {allTabManager.productObject.TypeNo.value eq null}"/>
            <div id="content" class="ui-widget">
                    <div class="post">
                    <ui:insert name="content_tab" >...</ui:insert>
                </div>
                </div>
            </p:layoutUnit>
         </p:layout>
    </h:form>

我试图通过commandlink在ajax请求后显示表单中的字段.但是,当我单击链接时,我收到malformedXML错误.xhtml文件如下所示:

            <h:form>    
                .
                .
                <tr>
                    <td>Product Image*:</td>
                    <td>
                        <h:graphicImage url="#{addItem.prodFileName}" width="100" height="100"/>
                        <br /><h:commandLink  value="change image" >
                            <f:ajax event="click" render="uploadimage" execute="@this" listener="#{addItem.ChangeImage}"/>
                        </h:commandLink>
                    </td>
                </tr>

                <tr >
                    <td>
                        <t:inputFileUpload rendered ="#{addItem.editImgChange}" label="editImage" id="uploadimage" value="#{addItem.uploadedFile}" />
                        <h:messages for="prodimage"/>
                    </td>
                </tr>
                .
                .
            </h:form>

AddItem bean是RequestScoped,它有以下代码行:

    @ManagedBean
    public class AddItem extends AbstractBean {
        //..
    boolean editImgChange=false;
        //...           
    public void ChangeImage(){
    this.editImgChange=true;
        }
    }

Inshort,我想只在用户点击更改图像链接后显示t:inputFileUpload字段.我在AddItem bean中保留了一个标志editImgChange,其初始值为false,一旦用户单击更改图像链接,该标志就会更改为true.该程序转到ChangeImage()方法,但之后我得到错误

"malformedXML:更新期间:找不到j_idt30:uploadimage"

.

我也会对一个完全不同的解决方案感到高兴,为了达到同样的效果,我的设计很糟糕.

以下代码是关于一个表,我可以在其中添加(commandButton)或删除(commandLink)行.这两个按钮都在工作并调用相应的bean方法.但是,对于每次单击添加按钮将更新表立即添加一行,对于删除按钮,我必须单击它两次以删除行.即使第一次没有删除该行,也会调用bean方法.我该怎么办？谢谢!

    <h:form id="form">
        <table>
            <tr>
                <td>
                    <h:panelGrid columns="2" width="100%">
                        <p:dataTable id="univertitiesTable" value="#{universityBean.universityList}" var="university"
                            editable="true" editMode="cell" style="align:center;" >

                            </p:column>
                        </p:dataTable>

                        <p:commandButton value="+" update="univertitiesTable" id="addButton" ajax="true"
                            actionListener="#{universityBean.addUniversity}"
                            styleClass="ui-priority-primary"  />

                    </h:panelGrid>                  
                </td>
            </tr>
            <tr>
                <td colspan="2" align="center">
                    <h:commandButton id="save" value="Save"

                </td>
            </tr>
        </table>    
    </h:form>

I tried this but my commandlink disappeared. When i tried to find with firebug, it was there but with size 0 x 0 px.

.myNewButton {
width: 50px !important;
height: 50px !important;
background-image: url('/resources/img/e_menu_icons/x.png')    !important ;
}

.myNewButton:hover {
width: 50px !important;
height: 50px !important;
background-image: url('/resources/img/e_menu_icons/e.png') !important ;
}


<p:commandLink  styleClass="myNewButton" value=""
               oncomplete="myDialog.show(); return false;"
action="#{myBean.actionMyAction()}">
</p:commandLink>

我有一个命令链接如下.

<h:commandLink value="Home" action="homePage">
</h:commandLink>

这工作正常,但我需要一个图像而不是文本值.图像必须充当命令链接.

我怎样才能做到这一点？

我有一个分页的数据表,我想用数据表外的命令链接更改当前页面,我怎么能得到它？

<p:commandLink title="changePage" action="#{myBean.changeMethod}"
   update="myDataTable" />
<p:dataTable id="myDataTable" var="myItem" paginator="true" rows="1"
   value="#{myBean.ListOfItem}" binding="#{myBean.DataTable}">
  ...
  ...
</p:dataTable>

问候!

在我的JSF文件中,我在开始时就在下面.

<h:form><h:commandLink value="Create New Staff Account" action="adminCreateStaffMember"/></h:form>.

通过使用这个,当我创建时,Create New Staff Account我被重新定向到我有表格的页面来创建新帐户.

但是,当我使用相同的内部时dataTable,不采取行动.我还在同一页上:(

<h:dataTable var="c" value="#{newStaffMemberServiceBean.newStaffMemberDataBeanList}"
  styleClass="order-table"
  headerClass="order-table-header"
  rowClasses="order-table-odd-row,order-table-even-row"
  border="1" id="staffListDataTable" width="100%">

  <h:column>
    <f:facet name="header">
       Staff Member Name
    </f:facet>
    <h:form><h:commandLink value="Create New Staff Account" action="adminCreateStaffMember"/></h:form>
  </h:column>
</h:dataTable>

实际上我想要打印的是我将使用的相应工作人员的详细信息f:setPropertyActionListener.但由于上述情况不起作用,我不会继续.

请建议我哪里出错了.

更新1

我newStaffMemberServiceBean在RequestScoped

@ManagedBean(name = "newStaffMemberServiceBean")
@RequestScoped
public class NewStaffMemberServiceBean {
    // some code
}

更新2

HTML Generated如下

在外面 dataTable

<div align="right">
<form id="j_idt35" name="j_idt35" method="post" action="/adminManageStaffMember" enctype="application/x-www-form-urlencoded">
<input …

我试图在点击PrimeFace CommandLink时打开PrimeFace ConfirmDialog.但是当点击链接时,对话框会暂时打开,但会立即消失,我猜这个页面正在提交.这是代码:

<p:commandLink value="Delete" onclick="confirmation.show()"  />

<p:confirmDialog message="Are you sure, you want to delete ?"  header="Initiating deleting process"  widgetVar="confirmation">  
    <p:commandButton value="Yes Sure"  onclick="confirmation.hide()"  actionListener="#{adminCtrl.deleteUserById}" update="userData" >
        <f:attribute name="delete" value="#{user.userId}" />
    </p:commandButton>  
    <p:commandButton value="Not Yet" onclick="confirmation.hide()" type="button" />   
</p:confirmDialog>

如何通过这种方式使对话框保持打开状态？

在PrimeFace ShowCase中,该示例处理CommandButton并且该工作正常,但我的要求是使用CommandLink.

可能吗？任何指针都对我很有帮助.

p:commandLink操作不会触发我的视图bean.我尝试过很多东西,但是我没有实现:((应该有一个简单的问题.如果你能帮助我,我将不胜感激.
