Summary

remove HTMLFrameSetElement’s anonymous getter which is non-standard.


Motivation

This non-standard getter was added 13 years ago to fix a compatibility issue

at the time: https://trac.webkit.org/changeset/8717/webkit

but it is not non-standard and nowadays it seems not used.


Interoperability and Compatibility Risk

very low. because this feature is not standard.

it is just legacy code from old webkit.

so webkit and blink have only supported it.


Edge: not supported

Firefox: not supported

Safari: Supported


Alternative implementation suggestion for web developers

this is non-standard. so we don’t need to provide an alternative.


Usage information from UseCounter

https://www.chromestatus.com/metrics/feature/timeline/popularity/2235

we are tracking this when it return non-null value. it is about 0.0001%


Entry on the feature dashboard

Requesting approval to remove too?

Yes. i would like to show a deprecation message before remove it.

could you recommend schedule how long show the message?

LGTM1.

The code for this is here:

This is implemented entirely in terms of web-exposed APIs and after some experimenting I think this is the simplest equivalent JS:
function getFrameByName(frameset, name) {
    try {
        return frameset.children.namedItem(name).contentDocument.defaultView;
    } catch (e) {
        return null;
    }
}

Regarding the deprecation period, let's say just a single cycle, given how rarely used this is.
