英文:
Can you filter a table/collection in PowerApps by one thing OR another?
问题
我正在尝试在PowerApps中过滤一个集合，如下所示：
Filter(AllRooms, "ComputerRoom" || "LaptopRoom" in Name)
然而，当我尝试这样做时，没有任何房间显示出来。如果我只使用一个过滤器（"ComputerRoom"或"LaptopRoom"），则正确的房间会显示出来。这是语法问题吗？还是有些事情是不可能的？
AllRooms 包含：
"ComputerRoom 1"
"ComputerRoom 2"
"ComputerRoom 3"
"LaptopRoom A"
"LaptopRoom B"
"ClassRoom 1"
"ClassRoom 2"
"ClassRoom 3"
"ClassRoom 4"
英文:
I'm trying to filter a collection in PowerApps like so:
Filter(AllRooms, "ComputerRoom" || "LaptopRoom" in Name)
However when I try this none of my rooms come up. If I use only one filter ("ComputerRoom", or "LaptopRoom") then the correct rooms come up. Is this is syntax thing? Or something that just isn't possible?
AllRooms contains;
"ComputerRoom 1"
"ComputerRoom 2"
"ComputerRoom 3"
"LaptopRoom A"
"LaptopRoom B"
"ClassRoom 1"
"ClassRoom 2"
"ClassRoom 3"
"ClassRoom 4"

你可以使用以下表达式根据一个值或另一个值来筛选房间：
Filter(AllRooms, "ComputerRoom" in Name || "LaptopRoom" in Name)
|| 运算符可用于组合两个布尔（true/false）值；当用于你最初的问题时，它实际上试图将值 "ComputerRoom" 和 "LaptopRoom" 转换为布尔值，然后进行“或”操作，这就是为什么它不按你的预期工作的原因。
英文:
You can use the following expression to filter the rooms based on one value or the other:
Filter(AllRooms, "ComputerRoom" in Name || "LaptopRoom" in Name)
The || operator can be used to combine two Boolean (true/false) values; when used as your original question, it is actually trying to convert the values "ComputerRoom" and "LaptopRoom" to boolean values before "or-ing" them, which is why it's not working as you expect.
