Magento Footer JS

A common web development technique to improve page load times is to move JavaScript to the end of the page. A common frustration for frontend Magento developers is the inability to do this due to the amount of inline JavaScript found in templates.

This extension observes for the core_block_abstract_to_html_after event, removes any javascript it finds and appends it to the end of the body.

Tested against:

  • CE 1.9
  • EE 1.14 (inc FPC)

Usage

Enable the extension in System > Configuration > Advanced > Developer > JavaScript Settings > Move JavaScript to Footer.

Add name of blocks with JS which must not be moved to footer in System > Configuration > Advanced > Developer > JavaScript Settings > FooterJS Excluded Blocks. Enter block names separated with a comma. Please note, JS libraries are moved to footer so be careful excluding JS which has dependencies.

Also there is another way to exclude some JS from moving to the footer - add attribute data-footer-js-skip="true" to script tag. Currently there is no way to exclude JS added using addJs/addItem in layout.
