(JavaScript API 1.3 for Office) Custom Properties GetItemOrNull
问题 I've created this a couple days ago in which i needed help regarding how to add custom properties to a said document. First of all, I'm running Word 1701(7766.2047). Let's say I have a method In which I return a said custom property. First I'd check if the custom property has been created already. I would do this with a simple getItemOrNullObject(key) and.. If returns null Then simply create it AND return it Else return it It is of my understanding that I need to do a return context.sync()
