説明

When a JavaScript file is loaded via the wp_enqueue_script function, Async JavaScript will add an async or defer attribute.

There are several ways an external JavaScript file 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 defer is present and async is not 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

Using async or defer helps to eliminate render-blocking JavaScript in above-the-fold content. This can also help to increase your pagespeed which in turn can assist in improving your page ranking.

Want more control? Async JavaScript Pro allows you to:

Selective ‘async’ – choose which JavaScripts to apply ‘async’ to
Selective ‘defer’ – choose which JavaScripts to apply ‘defer’ to
Exclude individual scripts – choose which JavaScripts to ignore
Exclude plugins – choose local plugin JavaScripts to ignore
Exclude themes – choose local theme JavaScripts to ignore

インストール

Just install from your WordPress “Plugins | Add New” screen and all will be well. Manual installation is very straight forward as well:

Upload the zip-file and unzip it in the /wp-content/plugins/ directory
WordPress の「プラグイン」メニューからプラグインを有効化してください
Go to Settings – Async JavaScript menu to load setings page

Where can I get help?

Async JavaScript is supported exclusively via our Support Ticketing System at https://cloughit.com.au/support/

What support do you provide?

We will provide support for any functionality of the Async JavaScript plugin itself, suggestions for theme / plugin support and suggestions on how Async JavaScript could be improved.

What support don’t you provide?

We will not provide support for questions such as ‘Why is Async JavaScript not making any improvement on my site?’. If you need this level of support we offer a bundled Async JavaScript Pro plus Installation & Configuration (homepage only) AUD $155.00 (buy now!)

Can I use the WordPress Forums to get support for Async JavaScript?

No. Support is provided via our Support Ticketing System at https://cloughit.com.au/support/

Can I email the author directly to get support for Async JavaScript?

No. Support is provided via our Support Ticketing System at https://cloughit.com.au/support/

What about CSS?

As the name implies, Async JavaScript is built to enhance JavaScript loading only. Async JavaScript does not have any impact on CSS.

We recommend using the awesome Autoptimize plugin alongside Async JavaScript for CSS optimization.

Do you have a pro version?

Yes we do! Here are some of the benefits of Async JavaScript Pro:

Selective ‘async’ – choose which JavaScripts to apply ‘async’ to
Selective ‘defer’ – choose which JavaScripts to apply ‘defer’ to
Exclude individual scripts – choose which JavaScripts to ignore
Exclude plugins – choose local plugin JavaScripts to ignore
Exclude themes – choose local theme JavaScripts to ignore

I want out, how should I remove Async JavaScript?
