我的问题跟踪应用程序有几个类别（客户端、分配对象、模块/类型、优先级、状态、构建等）。有几个视图有两个分类列（EG：Client 和 AssignedTo、Client 和 Module、AssignedTo 和 Priority、PPriority 和 Client 等。

我正在使用 XPages Mobile 控件实现移动页面。我想简化事情，以便移动主页上的视图选择驱动到一个用于选择适当的第一类别的页面，该页面又驱动到一个用于选择第二个类别的页面。我不明白的是，一旦第一个类别值的选择完成，第二个类别选择页面打开，之前选择的值是什么？

到目前为止，这是我的示例页面：

<xe:singlePageApp
    id="singlePageApp1"
    selectedPageName="mhome">
    <xe:appPage
        id="appPage1"

        <xe:djxmHeading
            id="djxmHeading1"

技术 1：
djxmLineItem 事件支持 onClick 事件事件，尽管 Xpages 中没有它的文档（我已经找到）。它作为 dojo 的一部分记录在 dojox.mobile ListItem 下。

如有必要，为另一个控件创建 onClick 事件并复制 xe:djxmLineItem 标记下的代码。您可以使用延迟评估 (#) 来访问 indexVar 以识别重复中的哪个 ListItem 已被单击。

添加事件处理程序的一个主要缺点是，您必须触发目标页面内某些内容的部分刷新，以便呈现其内容。这反过来意味着必须预先加载页面内容才能使刷新目标可用。这很可能是当前移动控件实现中的一个错误，但它可能是一个痛苦！

技术 2：
跟踪页面和所选项目而没有上述副作用。不要添加事件处理程序。取而代之的是......以这样的方式创建列表项，即项目的“id”作为 moveTo 属性的参数添加。

例子：

<xe:djxmRoundRectList id="menuList">
  <xp:repeat value="#{compositeData.view.listItems}"
    var="listItem" indexVar="menuIndex" id="listRepeat" rows="999">
    <xe:djxmLineItem id="listItem"
      label="#{listItem.label}" moveTo="#{compositeData.view.moveTo}&amp;id=#{listItem.id}&amp;clear=true"
      rightText="#{listItem.rightText}">
    </xe:djxmLineItem>
  </xp:repeat>
</xe:djxmRoundRectList>

可以在页面底部添加以下代码，为每个appPage的transition事件添加一个事件监听器。

<xp:scriptBlock id="scriptBlock1">
    <xp:this.value>
        <![CDATA[XSP.addOnLoad(function(){
          dijit.registry.byClass("extlib.dijit.mobile.View").forEach(function(widget, index, hash){
          dojo.connect(widget, "onBeforeTransitionOut", function(moveTo, dir, transition, context, method){
          var deferred = adminService.setMoveTarget(moveTo);
        });
      });
    });
  ]]>
  </xp:this.value>
</xp:scriptBlock>

事件处理程序正在调用将详细信息传递给 bean 的 jsonRpcService（在页面转换发生之前）。

<xe:jsonRpcService id="jsonRpcService1" serviceName="adminService"
  state="true">
  <xe:this.methods>
    <xe:remoteMethod name="setMoveTarget"
      script="AdminSession.setMoveTarget(moveTo);return true;">
      <xe:this.arguments>
        <xe:remoteMethodArg name="moveTo"></xe:remoteMethodArg>
        </xe:this.arguments>
      </xe:remoteMethod>    
  </xe:this.methods>
</xe:jsonRpcService>

AdminSession bean 中的 setMoveTarget() 方法应该能够解析出参数以识别所选项目以及跟踪页面转换。

注意：添加 clear=true 是一种确保页面的 pageContent 仅在向前移动到页面时而不是在返回同一页面时重置的方法。

所以这里是修改后的方法的代码，它适用于这个警告......

  1. 视图仅在第一列进行分类，尽管可能不需要。该页面使用“按列值过滤”来显示选定的文档。这是因为 subcatAppPage 的重复控件不会找到多个值，除非我从视图中删除了分类。

  2. 我在页面上使用了一个 dataContext 控件来定义将要显示的视图。它需要更多的复杂性，但这目前有效：

    <xp:this.dataContexts>
  <xp:dataContext
    var="viewListItems">
    <xp:this.value><![CDATA[#{javascript:
      try {
        var returnVal = [];
        returnVal.push({name:"Issues by Assigned To By Client", alias:"ByAssignedToClient", cats:["AssignedTo","Client"]});
        returnVal.push({name:"Issues by Assigned To By Module", alias:"ByAssignedToType", cats:["AssignedTo","Type"]});
        returnVal.push({name:"Issues by Client By Assigned To", alias:"ByClientAssignedTo", cats:["Client","AssignedTo"]});
        returnVal.push({name:"Issues by Client By Module", alias:"ByClientType", cats:["Client","Type"]});
        return returnVal;
      } catch(e) {
         _dump(e);
      }
    }]]></xp:this.value>
  </xp:dataContext>
</xp:this.dataContexts>

现在这里是移动控件：

<xe:singlePageApp
        id="singlePageApp1"
        selectedPageName="mhome">
        <xe:appPage
            id="homeAppPage1"
            pageName="mhome">
            <xe:djxmHeading

                label="Home">
            </xe:djxmHeading>
            <xe:djxmRoundRectList id="djxmRoundRectList1">
