Version 12.5

12.5.1

Restored IE 11 compatibility, which was broken since 12.2.0. See #414.
Thanks to @ninosaurus for reporting.

12.5.0

The once-private _loadingCount property is now public and renamed to loadingCount. This property contains the number of images that are currently downloading from the network, limitedly to the ones managed by an instance of LazyLoad. This is particularly useful to understand whether or not is safe to destroy an instance of LazyLoad. See implementation in the destroy demo.

Thanks to @wzhscript and @eugene-stativka.

Version 12.4

12.4.0

Video posters can now be loaded lazily, as requested in #365

Version 12.3

12.3.0

Callbacks now pass more arguments.

callback_enter, callback_exit now pass:

1. the DOM element that entered / exited the viewport
2. the IntersectionObserverEntry that triggered the enter/exit event
3. the LazyLoad instance

callback_load, callback_error, callback_reveal now pass:

1. the DOM element that entered / exited the viewport
2. the LazyLoad instance

callback_finish now passes:

1. the LazyLoad instance

The README file has been updated accordingly.

Version 12.2

• Reorganized code
• Improved native lazy loading demos
• Aligned console messages throughout all demos.

12.0.0-beta.0

• Refactored the constructor and the update method

Version 11.0

Version 11

11.0.6

Restored the callback_set callback as deprecated, in order to make the upgrade from v.10 easier.

11.0.5

Fixed the module property of this package.json, which was pointing to a non-existing dist file.

11.0.4

Fixed the main property of this package.json, which was pointing to a non-existing dist file.

11.0.3

Rollback of the patch applied in 11.0.2 since it gave strange results in some cases. See #293. Thanks to @davejamesmiller for the analysis and the report.

11.0.1

Squashed a nasty bug that occurred on IE 11 and Safari when the IntersectionObserver polyfill wasn't loaded before LazyLoad.

11.0.0

• Changed bundle file name of ES Module from lazyload.es2015.js to lazyload.esm.js
• Removed the to_webp option (see issue #288)
• Ceased support and development of LazyLoad v.8 (see issue #306)
• Callbacks renewal :: POSSIBLE BREAKING CHANGE

  • Callback callback_exit (new) is called whenever an element exits the viewport, even if load_delay is set
  • Callback callback_reveal (new) is called when an element is about to be revealed, and its attribute values were copied from the data- attributes to the actual ones.
