Power BI 提供兩種方式來與視覺效果互動 - 選取和篩選。 下列範例示範如何從某個視覺效果選取專案,並在報表中通知其他視覺效果新的選取狀態。 介面會對應至Selection物件: TypeScript複製 exportinterfaceISelectionId { equals(other: ISelectionId):boolean; includes(other: ISelectionId, ignoreHighlight?:boolean):...
PowerShell 複製 $a = (1, 2) -eq 3 $a.GetType().Name $a.Count 輸出 複製 Object[] 0 但也有一些例外:內含專案和類型運算元一律會傳 回布爾 值 運算符 -replace 會傳回取代結果 -match和-notmatch 運算子也會填入自動變數,$Matches除非表達式左邊是集合。

Power BI 提供了两种与视觉对象交互的方式 - 选择和筛选。 下面的示例演示如何从一个视觉对象中选择一个项,并就新的选择状态通知报表中的其他视觉对象。 接口对应于一个Selection对象: TypeScript复制 exportinterfaceISelectionId { equals(other: ISelectionId):boolean; includes(other: ISelectionId, ignoreHighlig...
