MediaQueryListListener

This feature is outdated. The MediaQueryList.addListener() callback is now a plain function and called with the standard MediaQueryListEvent 对象。

A MediaQueryList object maintains a list of media queries on a Document , and handles sending notifications to listeners when the media queries on the document change.

This makes it possible to observe a document to detect when its media queries change, instead of polling the values periodically, if you need to detect changes to the values of media queries on a document.

A MediaQueryListListener is a callback function that gets invoked with a single argument, the MediaQueryList for which the evaluated result changed.
