Ms office Office加载项PowerPoint-将自定义数据存储到文件不起作用
我想将自定义数据存储到PowerPoint演示文稿文件中。我用这个例子: 但我希望在Office加载项卸载期间存储数据(对于用户关闭演示文件时的示例) 所以我使用Ms office Office加载项PowerPoint-将自定义数据存储到文件不起作用,ms-office,powerpoint,office-js,office-addins,Ms Office,Powerpoint,Office Js,Office Addins,我想将自定义数据存储到PowerPoint演示文稿文件中。我用这个例子: 但我希望在Office加载项卸载期间存储数据(对于用户关闭演示文件时的示例) 所以我使用window.onunload=function(){}…来检测演示文档何时开始关闭 在关闭PowerPoint时,方法: Office.context.document.settings.saveAsync() 返回错误:保存失败。错误:发生内部错误。 代码示例 Home.html: <html> <head>
window.onunload=function(){}…
来检测演示文档何时开始关闭
在关闭PowerPoint时,方法:
Office.context.document.settings.saveAsync()
返回错误:保存失败。错误:发生内部错误。

不幸的是,您不能以这种方式利用onunload事件。当外接程序关闭时,它与文档的连接也将关闭 我建议从
saveToPropertyBag()
函数中调用Office.context.document.settings.saveAsync()
。除非您经常对属性包进行更改,否则不会有太多开销。或者,如果需要快速连续地进行几次更改,您可以立即调用saveAsync()
如果对关闭/关闭事件感兴趣,则[Office Developer Platform UserVoice]()中当前有一个功能请求,可以使用您的投票: 感谢您的澄清,onunload/onclose对于存储当前的应用程序状态来说是很好的功能。这里的挑战是,在您的外接程序和文档之间的连接被破坏之后,您的外接程序中的onunload/onclose是否会出现。目前,还没有一种方法可以在拆卸发生之前捕捉到关闭。
