目前我正在通过新的Javascript API（office.js）开发Word的加载项。 Javascript API为开发人员提供了开发任务窗格的可能性，这是一个显示在文档旁边的列。这些任务窗口充当浏览器并显示公共或本地托管的网页。通过Javascript API，这些页面可以与文档进行交互。
单个加载项可以包含多个任务窗格，可以通过所谓的命令加载项打开。这些命令加载项可以是从功能区中的按钮到右键单击菜单中的选项的任何内容。这些命令加载项和任务窗格的规范在清单中定义。 word文档读取此清单，因此可以识别，可以打开哪些页面以及如何在Office中显示它们。
目标
理想情况下，我想创建一些文档，当用户打开时，会自动从此加载项打开某个任务窗格。文档A打开任务窗格A，文档B打开任务窗格B，等等。但是，为了这个问题，我只想集中讨论如何从包含多个任务窗格的清单中打开一个任务窗格。文档表明，这确实是可行的，因为您可以看到here。前面提到的链接指出，这可以通过以下几个步骤来实现。
（1）托管了一个关于office.js的网页。
（2）创建一个包含命令加载项和任务窗格的清单。应自动打开的任务窗格的ID为＆＃39; Office.AutoShowTaskpaneWithDocument＆＃39;。
<!--Example code, real manifest at the bottom of the question-->
<Action xsi:type="ShowTaskpane">
<TaskpaneId>Office.AutoShowTaskpaneWithDocument</TaskpaneId>
<SourceLocation resid="Contoso.Taskpane.Url" />
</Action>
（3）调整文档的Office Open XML，使其包含webextension。 webextension引用了manifest和Office.AutoShowTaskpaneWithDocument id，因此它将打开正确的taskpane。这是通过添加以下webextension xml文档（以及rels文档，此处未包含）来完成的。
<we:webextension xmlns:we="http://schemas.microsoft.com/office/webextensions/webextension/2010/11" id="[ADD-IN ID PER MANIFEST]">
<we:reference id="[GUID or Office Store asset ID]" version="[your add-in version]" store="[Pointer to store or catalog]" storeType="[Store or catalog type]"/>
<we:alternateReferences/>
<we:properties>
<we:property name="Office.AutoShowTaskpaneWithDocument" value="true"/>
</we:properties>
<we:bindings/>
<we:snapshot xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"/>
</we:webextension>
问题
该文档确实打开了一个任务窗格，但是它会在Taskpane模式集成中从SourceLocation打开该URL。用Office.AutoShowTaskpaneId标记的任务窗格将被完全忽略。
<!--Example code, real manifest at the bottom of the question-->
<!--Begin TaskPane Mode integration. This section is used if there are no VersionOverrides or if the Office client version does not support add-in commands. -->
<Hosts>
<Host Name="Document" />
</Hosts>
<DefaultSettings>
<SourceLocation DefaultValue="[baseurl]" />
</DefaultSettings>
<!-- End TaskPane Mode integration. -->
我假设忽略了包含加载项所有信息的VersionOverrides标记。这将导致文档打开DefaultSettings标记的后备，从而打开错误的任务窗格。不幸的是，我完全迷失了如何解决这个问题。我有最新版本的Word，因此不应忽略VersionOverrides标记。
非常感谢任何帮助！
修改 我设法解决了这个问题，但我不确定是什么导致了解决方案。我没有调整由本地客户端加载项生成的OOXML，而是使用了由服务器端加载项生成的OOXML。
虽然我不确定实际问题是什么。我认为%LOCALAPPDATA%\Microsoft\Office\16.0\Wef\的Word缓存发挥了作用。我做的唯一更改是使用服务器运行加载项调整OOXML并事先清理缓存。

答案 0 :(得分：1)
您只能将 TaskpaneId 设置为 Office.AutoShowTaskpaneWithDocument 。分配给该任务窗格的 SourceLocation 的URL在清单中进行了硬编码。在您的情况下，它是[baseurl]/Templates/Letter。因此，您为此加载项启用autoopen的每个文档都应该自动打开该字母。没有办法在另一个文档上安装相同的加载项（因此，完全相同的清单）并且具有不同的页面自动打开。
加载项是否自动打开[baseurl]/Templates/Letter？如果没有，你确定有一个具有该名称和路径的文件吗？它是HTML文件吗？如果在加载项运行时将浏览器窗口导航到该URL会发生什么？页面是否在浏览器中加载？
