jQuery API Documentation

Category: Version 1.9

Some APIs may have changed since this version was released. If using this version, find out about our version support.

All the aspects of the API that were added, or had a new signature added, in the corresponding version of jQuery.

Changes in jQuery 1.9 dealt primarily with removal or modification of several APIs that behaved inconsistently or inefficiently in the past.

A jQuery Migrate Plugin was offered to help developers with a transitional upgrade path.
