Definition

Namespace:

Microsoft.Web.WebView2.Core

Assembly:

Microsoft.Web.WebView2.Core.dll

Package:

Microsoft.Web.WebView2 v1.0.3065.39

Gets the origin initiating the external URI scheme launch.

C#

public string InitiatingOrigin { get; }

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.
