PerformanceScriptTiming: windowAttribution property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The windowAttribution read-only property of the PerformanceScriptTiming interface returns an enumerated value describing the relationship of the container (i.e., either the top-level document or an <iframe>) in which the long animation frame (LoAF)-causing script was executed, relative to the window running the current document.

Value

An enumerated value, which can be one of:

"ancestor"

The current document is a descendant of the document in which the script was executed, embedded inside it in an <iframe>.

"descendant"

The script was executed in a descendant document embedded inside the current document in an <iframe>.

"other"

The location of the document the script was executed in could not be determined.

"same-page"

The script was executed in a version of the current document embedded within the current document in an <iframe>.

"self"

The script was executed in the current document.
