TVML-TVOS一起渲染超过1个模板

Question

我最近开始使用TVML/TVJS，不知道如何处理以下问题。

手头的问题是在呈现页面时在同一页面上使用多个模板，即我想在ListTemplate上添加MenuBarTemplate，同样如此。

但是如果我在页面上同时添加这两个，它只显示ListTemplate，而不显示MenuTemplate

以下是代码片段：

<menuBarTemplate>
  <menuBar>
     <menuItem id="navigation_top_movies" data-identifier="list">
        <title>Top Movies</title>
     </menuItem>
     <menuItem id="navigation_genres" data-identifier="index">
        <title>Genres</title>
     </menuItem>
     <menuItem id="navigation_search" data-identifier="search">
        <title>Search</title>
     </menuItem>
     <menuItem id="navigation_edit" data-identifier="edit">
        <title>Edit</title>
     </menuItem>
     <menuItem id="navigation_settings_add" data-identifier="add_settings">
        <title>Add Settings</title>
     </menuItem>
  </menuBar>
</menuBarTemplate>
<productTemplate>
  <background>
  </background>
  <banner>
     <infoList>
        <info>
           <header>
           </header>
        </info>
     </infoList>
     <stack>
        <title>WWDC Road Trip</title>
        <row>
           <text><badge src="resource://tomato-fresh"/> 99%</text>
           <text>1hr 54min</text>
           <text>Comedy</text>
           <text>2015</text>
           <badge src="resource://mpaa-pg" class="badge" />
           <badge src="resource://cc" class="badge" />
        </row>
        <description allowsZooming="true" moreLabel="more">An aspiring developer gets a ticket to WWDC, but cant afford to fly there. Now he needs to get across country in time for the keynote, and the only person who can help him is his slacker roommate.</description>
        <text>Language information can go here</text>
        <row>
           <buttonLockup>
              <badge src="resource://button-preview" />
              <title>Preview</title>
           </buttonLockup>
           <buttonLockup type="buy">
              <text>$9.99</text>
              <title>Buy</title>
           </buttonLockup>
        </row>
     </stack>
     <heroImg src="path to images on your server/Car_Movie_720x1080.png" />
  </banner>
  </productTemplate>

这方面的任何帮助都将是伟大的。谢谢

每页只能有一个模板。当进入menuBarTemplate时，情况大致相同，但框架内部呈现所选选项卡，同时显示菜单和productTemplate

例如，使用menuBarTemplate并为第一个菜单项设置模板：

<menuBarTemplate>
  <menuBar>
     <menuItem id="navigation_top_movies" data-identifier="list" template="${this.BASEURL}templates/productTemplate.xml.js">
        <title>Top Movies</title>
     </menuItem>
     <menuItem id="navigation_genres" data-identifier="index">
        <title>Genres</title>
     </menuItem>
     <menuItem id="navigation_search" data-identifier="search">
        <title>Search</title>
     </menuItem>
     <menuItem id="navigation_edit" data-identifier="edit">
        <title>Edit</title>
     </menuItem>
     <menuItem id="navigation_settings_add" data-identifier="add_settings">
        <title>Add Settings</title>
     </menuItem>
  </menuBar>
</menuBarTemplate>

然后在一个名为productTemplate.xml.js:的单独文件中

var Template = function() { return `<?xml version="1.0" encoding="UTF-8" ?>
<document>
<productTemplate>
  <background>
  </background>
  <banner>
     <infoList>
        <info>
           <header>
           </header>
        </info>
     </infoList>
     <stack>
        <title>WWDC Road Trip</title>
        <row>
           <text><badge src="resource://tomato-fresh"/> 99%</text>
           <text>1hr 54min</text>
           <text>Comedy</text>
           <text>2015</text>
           <badge src="resource://mpaa-pg" class="badge" />
           <badge src="resource://cc" class="badge" />
        </row>
        <description allowsZooming="true" moreLabel="more">An aspiring developer gets a ticket to WWDC, but cant afford to fly there. Now he needs to get across country in time for the keynote, and the only person who can help him is his slacker roommate.</description>
        <text>Language information can go here</text>
        <row>
           <buttonLockup>
              <badge src="resource://button-preview" />
              <title>Preview</title>
           </buttonLockup>
           <buttonLockup type="buy">
              <text>$9.99</text>
              <title>Buy</title>
           </buttonLockup>
        </row>
     </stack>
     <heroImg src="path to images on your server/Car_Movie_720x1080.png" />
  </banner>
  </productTemplate>
</document>`
}

默认情况下，这将呈现菜单栏的第一个选项卡。如果为其他选项卡提供模板，则该选项卡将在维护菜单栏的同时自动更改。
