Powerpoint 加载项 - 在 Office.initialize 外部调用时，saveAsync 不会保存设置 [英] Powerpoint Add-In - saveAsync does not save settings when called outside of Office.initialize
问题描述
我正在为 PowerPoint 开发一个内容加载项，当用户使用 Office.context.document.settings 函数(get、set、remove 和 saveAsync).
但是，在 Office.initialize 函数之外进行的 saveAsync 调用似乎并没有实际保存当前设置，因为在重新加载演示文稿时，只有设置初始化时保存的数据被持久化.
为了演示，下面是一个计数器初始化为 1 并在每次加载页面或用户单击增量按钮时递增的最小示例:

这是一个错误还是我遗漏了什么?

不确定您是否更改了某些内容，但今天它似乎运行良好(重新加载不会更改计数器值)

错误又回来了，我的结局没有任何变化.
您需要调用 refreshAsync 在尝试读取给定值之前.这会将当前设置从文档中传入内存.
试试这个:
function getState(name) {Office.context.document.settings.refreshAsync(function(){返回 Office.context.document.settings.get(name);});}I'm developing a content add-in for PowerPoint and I'm trying to persist its state when the user reloads the presentation using the Office.context.document.settings functions (get, set, remove and saveAsync).
However, it appears that saveAsync calls made outside of the Office.initialize function do not actually save the current settings, as upon reloading of the presentation, only the settings saved during the initialization are persisted.
For demonstration, here is a minimal example of a counter initialized at 1 and incremented each time the page is loaded, or when the user clicks an Increment button:

When inserted into a presentation, this add-in first appear to behave correctly (the counter is incremented as expected and Settings saved. is displayed in the console log each time). However when reloading the presentation, and looking at the console log, we can see that the saveAsync call in the incrementCounter has no effect, i.e. the increments from the button clicking are not registered, but the increments from reloading the page are.
Is this a bug or am I missing something?
Edit 2018/01/19
Not sure if you changed something on your end, but today it seems to work perfectly (reloading does not change the counter value)
Edit 2018/05/23
The bug came back again without any change from my end.
You need to call refreshAsync prior to attempting to read a given value. This will reach the current settings from the document into memory.
Try this:
function getState(name) {
Office.context.document.settings.refreshAsync(function(){
return Office.context.document.settings.get(name);
});
}
