Question

我正在开发PowerPoint的内容加载项，并且当用户使用Office.context.document.settings函数重新加载演示文稿时，我试图保持其状态（get，{{ 1}}，set和remove）。

但是，saveAsync函数之外的saveAsync调用似乎并未实际保存当前设置，因为重新加载演示文稿时，只会保留初始化期间保存的设置。< / p>

为了演示，这里是一个初始化为1的计数器的最小示例，每次加载页面或用户单击“增量”按钮时都会递增：

的index.html

Office.initialize

app.js

<!DOCTYPE html>
<html>

<head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=Edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Counter Add-In</title>

    <!-- Office JavaScript API -->
    <script type="text/javascript" src="https://appsforoffice.microsoft.com/lib/1.1/hosted/office.debug.js"></script>
</head>

<body>
    <div>
        <h1>Counter Add-In</h1>
        <span id="test-message"></span>
        <button class="ms-Button" id="increment-button">Increment</button>
    </div>

    <script type="text/javascript" src="node_modules/core-js/client/core.js"></script>
    <script type="text/javascript" src="node_modules/jquery/dist/jquery.js"></script>
    <script type="text/javascript" src="app.js"></script>
</body>

</html>

反的manifest.xml

(function() {

  Office.initialize = function(reason) {
    $(document).ready(function() {
      switch (reason) {
        case 'inserted':
          console.log('The add-in was just inserted.');
          setState('counter', 1);
        case 'documentOpened':
          console.log('The add-in is already part of the document.');
          setState('counter', getState('counter') + 1);
          break;
      }
      $('#test-message').text(getState('counter') || 'NOT FOUND');
      saveState();

      // Callback functions for buttons
      $('#increment-button').click(incrementCounter);
    });
  };

  // Settings/State helpers
  function getState(name) {
    return Office.context.document.settings.get(name);
  }

  function setState(name, val) {
    console.log('Setting', name, 'to', val);
    Office.context.document.settings.set(name, val);
  }

  function saveState() {
    Office.context.document.settings.saveAsync(function(asyncResult) {
      if (asyncResult.status === Office.AsyncResultStatus.Succeeded) {
        console.log('Settings saved.');
      } else {
        console.warn('Settings save failed', asyncResult.status, asyncResult.error.message);
      }
    });
  }

  function incrementCounter() {
    var counter = getState('counter');
    setState('counter', counter + 1);
    $('#test-message').text(getState('counter'));
    saveState();
  }

})();

当插入到演示文稿中时，此加载项首先看起来表现正常（计数器按预期递增，并且每次都在控制台日志中显示<?xml version="1.0" encoding="UTF-8"?> <OfficeApp xmlns="http://schemas.microsoft.com/office/appforoffice/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:bt="http://schemas.microsoft.com/office/officeappbasictypes/1.0" xmlns:ov="http://schemas.microsoft.com/office/taskpaneappversionoverrides" xsi:type="ContentApp"> <Id>71a1a0ed-6cd0-4a6e-ad2d-015b8a8b43cb</Id> <Version>1.0.0.0</Version> <ProviderName>Test</ProviderName> <DefaultLocale>en-US</DefaultLocale> <DisplayName DefaultValue="DisplayName" /> <Description DefaultValue="Description"/> <IconUrl DefaultValue="https://localhost:3000/assets/icon-32.png" /> <HighResolutionIconUrl DefaultValue="https://localhost:3000/assets/hi-res-icon.png"/> <AppDomains></AppDomains> <Hosts> <Host Name="Presentation" /> </Hosts> <DefaultSettings> <SourceLocation DefaultValue="https://localhost:3000/index.html" /> </DefaultSettings> <Permissions>ReadWriteDocument</Permissions> <VersionOverrides xmlns="http://schemas.microsoft.com/office/taskpaneappversionoverrides" xsi:type="VersionOverridesV1_0"> <Hosts> <Host xsi:type="Presentation"></Host> </Hosts> <Resources></Resources> </VersionOverrides> </OfficeApp>）。但是，当重新加载演示文稿并查看控制台日志时，我们可以看到Settings saved.中的saveAsync调用无效，即按钮点击的增量未注册，但增量来自重新加载页面。

这是一个错误还是我错过了什么？

不确定你是否改变了一些东西，但今天看起来效果很好（重新加载不会改变计数器值）

这个错误再次回来，没有任何改变。

Answer 1

您需要在尝试读取给定值之前调用refreshAsync。这将从文档到内存达到当前设置。

试试这个：

function getState(name) {
  Office.context.document.settings.refreshAsync(function(){
     return Office.context.document.settings.get(name);
  });
}

Powerpoint加载项 - 在Office.initialize之外调用时，saveAsync不保存设置
