Primefaces Dialog Framework - 来自menuitem的dialogReturn事件 [英] Primefaces Dialog Framework -- dialogReturn event from menuitem
问题描述
我在 Table.xhtml 中有一个主要 p：datatable 并且有一个 p ：commandbutton 在我用于使用对话框架打开对话框的同一页面上。与对话框相关的内容位于 Dialog.xhtml 中。我使用名为 TableDialog.java 的单个支持bean用于 Table.xhtml 和对话框.xhtml 。当对话框关闭时， p：datatable 中的值会相应地使用
I have a primefaces p:datatable in Table.xhtml and have a p:commandbutton on the same page which I am using to open a dialog using dialog framework. The content related to dialog is in Dialog.xhtml. I am using a single backing bean named TableDialog.java for both Table.xhtml and Dialog.xhtml. When the dialog is closed, the values in the p:datatable are updated accordingly using the
<p:ajax event="dialogReturn" listener="#{tableDialog.test}" update = ":form:colors" />
Table.xhtml 如下
<?xml version="1.0" encoding="ISO-8859-1" ?>

这里是Dialog.xhtml
and here is the Dialog.xhtml

TableDialog.java包含以下代码
the TableDialog.java contains the following code
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import org.primefaces.context.RequestContext;
@ManagedBean
@SessionScoped
public class TableDialog {
public ArrayList<String> resourceList=new ArrayList<String>();
private String selected;
String attributeValue = null;
public TableDialog(){
this.resourceList.add("Black");
this.resourceList.add("White");
}
public void updateValue(){
System.out.println("update value");
RequestContext context = RequestContext.getCurrentInstance();
Map<String, Object> options = new HashMap<String, Object>();
options.put("resizable", false);
options.put("dynamic", true);
options.put("height", 100);
options.put("width", 300);
options.put("contentHeight", 100);
options.put("contentWidth", 250);
context.openDialog("Dialog", options, null);
}
public void test(){
System.out.println("test");
}
public void cancelValue(){
RequestContext context = RequestContext.getCurrentInstance();
context.closeDialog(this.attributeValue);
System.out.println("cancel update resource attribute value");
this.attributeValue = null;
System.out.println("this.attributevalue = " + this.attributeValue);
}
public void saveValue(){
RequestContext context = RequestContext.getCurrentInstance();
if (this.attributeValue == null)
{
System.out.println("No value");
context.execute("noValueDialog.show()");
return;
}
System.out.println("this.attributevalue = " + this.attributeValue);
this.resourceList.add(this.attributeValue);
this.attributeValue = null;
context.update("form:resourceAttributeValueDataTable");
RequestContext.getCurrentInstance().update("form:resourceAttributeValueDataTable");
context.closeDialog(this.attributeValue);
System.out.println("after hidden button execute " );
}
public String getSelected() {
return selected;
}
public void setSelected(String selected) {
this.selected = selected;
}
public ArrayList<String> getResourceList() {
return resourceList;
}
public void setResourceList(ArrayList<String> resourceList) {
this.resourceList = resourceList;
}
public String getAttributeValue() {
return attributeValue;
}
public void setAttributeValue(String attributeValue) {
this.attributeValue = attributeValue;
}
}
一切正常。
我的问题是：
我想使用 p：contextMenu 打开对话框。 p：menuitem 正确打开对话框，但在关闭对话框后，我无法更新 p：dataTable 。由于对话框架仅支持 p：commandButton 或 p：commandLink 我无法使用
I want to use p:contextMenu for opening the dialog. p:menuitem opens the dialog correctly but I am unable to update the p:dataTable after the dialog is closed. As the dialog framework only supports p:commandButton or p:commandLink I can't use
<p:ajax event="dialogReturn" />
在 p：menuitem 中。在互联网上搜索工作我在 http：//找到了解决方案forum.primefaces.org/viewtopic.php?f=3&t=32131 。它说
inside p:menuitem. Searching for a work around on the internet I found the solution at http://forum.primefaces.org/viewtopic.php?f=3&t=32131. It says
现在，您可以执行以下操作来解决方法：
"For now, you can do the following to workaround :
- 从
menuitem删除p：ajax - 添加
p：commandbuttonxhtml并添加id =...和style =display：none - 添加onclick = ...到menuitem使用javascript来触发> commandbutton的click（）事件，并引用名称应为formID：buttonID的按钮。
- Remove
p:ajaxfrommenuitem - Add
p:commandbuttonxhtml and add id="..." and style="display:none" - Add onclick="..." to menuitem to use javascript to trigger the click() event of the >commandbutton, and reference the button where name should be "formID:buttonID"."
我是java，primefaces和ajax的新手，对javascript和jquery一无所知。因此，我无法弄清楚究竟要写在内部onclick =........
I am a newbie in java, primefaces and ajax and know nothing about javascript and jquery. So I am unable to figure out what exactly to write inside onclick="........"
<p:menuitem value="Add" actionListener="#{tableDialog.updateValue}"
update=" :form:colors " onclick="........" >
这样每当我选择菜单项时，都会执行隐藏按钮。任何帮助都将受到高度赞赏。
so that whenever I select a menu item the hidden button is executed. Any help will be highly appreciated.
推荐答案
我在如何在JavaScript中触发隐藏的JSF commandLink？
Table.xhtml的更新版本包含
The updated version of Table.xhtml contains
<h:form id="form">
<p:dataTable id="colors" var="col" value="#{tableDialog.resourceList}" rowKey="#{col}"
selection="#{tableDialog.selected}" selectionMode="single">
<p:column headerText="Model">
#{col}
</p:column>
</p:dataTable>
<p:contextMenu for="colors">
<p:menuitem value="Add" onclick="triggerHiddenEvent(); return false;"
update=" :form:colors " >
</p:menuitem>
</p:contextMenu>
<p:commandButton id="hiddenCommand" styleClass="button" action="#{tableDialog.updateValue}" style="display:none">
<p:ajax event="dialogReturn" update = ":form:colors" />
</p:commandButton>
<h:outputScript >
function triggerHiddenEvent() {
document.getElementById("form:hiddenCommand").click();
}
</h:outputScript>
</h:form>
