Async Javascript Settings

Enable Async Javascript

When you enable Async Javascript, when a script is loaded via the 'wp_enqueue_script' method, this plugin will add a 'async' or 'defer' attribute.
This action helps to eliminate render-blocking JavaScript in above-the-fold content. This can also help to increase your pagespeed which in turn will assist in improving your page ranking.
There are several ways an external script can be executed:
  • If async is present: The script is executed asynchronously with the rest of the page (the script will be executed while the page continues the parsing)
  • If async is not present and defer is present: The script is executed when the page has finished parsing
  • If neither async or defer is present: The script is fetched and executed immediately, before the browser continues parsing the page
Note: There have been instances where enabling Async Javascript has 'broken' the javascript delivery. Should this happen to you, I highly recommend installing the Autoptimize plugin which will combine your javascript, further enhancing pagespeed and eliminating this issue.

Async Javascript Method

Please select the method (async or defer) that you wish to enable:
Method /> Async /> Defer

Script Exclusion

Please list any scripts which you would like excluded from being Async/Defered during page load. (comma seperated list eg: jquery.js,jquery-ui.js)
Exclusions

Async Javascript For Plugins

Note: This will attempt to add the 'async' or 'defer' attribute to scripts loaded via a plugin (ie, not via 'wp_enqueue_script'). If you have a plugin that you would like added to this list please email support@cloughit.com.au
