member this.InitiatingOrigin : string

Public ReadOnly Property InitiatingOrigin As String

Property Value

String

Remarks

The origin will be an empty string if the request is initiated by calling Navigate(String) on the external URI scheme. If a script initiates the navigation, the InitiatingOrigin will be the top-level document's Source, i.e. if window.location is set to "calculator://", the InitiatingOriginwill be set tocalculator://. If the request is initiated from a child frame, the InitiatingOriginwill be the source of that child frame. If theInitiatingOriginis [opaque](https://html.spec.whatwg.org/multipage/origin.html#concept-origin-opaque), theInitiatingOrigin` reported in the event args will be its precursor origin. The precursor origin is the origin that created the opaque origin. For example, if a frame on example.com opens a subframe with a different opaque origin, the subframe's precursor origin is example.com.
