web api instance property
NotRestoredReasons: children property
Limited availability
The children read-only property of the
NotRestoredReasons interface returns an array of NotRestoredReasons objects, one for each child <iframe> embedded in the current document, which may contain reasons why the top-level frame was blocked relating to the child frames.
Each object has the same structure as the parent object — this way, any number of levels of embedded <iframe>s can be represented inside the object recursively.
Value
An array of NotRestoredReasons objects.
If the frame has no children, the array will be empty; if the document is in a cross-origin <iframe>, children will return null.
Examples
See Monitoring bfcache blocking reasons for examples.
