[Demo video](https://youtu.be/YJ8TQ3bh-TA) Flying Scripts delay the execution of JavaScript until there is no user activity. You can specify keywords to include JavaScripts to be delayed. There is also a timeout which executes JavaScript when there is no user activity. ### Why should I use this plugin? JavaScript is very resource-heavy. By delaying the execution of non-critical JavaScript( that are not needed for the initial render), you’re prioritizing and giving more resources to critical JavaScript files. This way you will reduce render time, time to interactive, first CPU idle, max Potential input delay etc. This will also reduce initial payload to browsers by reducing the no. of requests. ### Support * [Official Support Forum](https://wordpress.org/support/plugin/flying-scripts/) * [Facebook Group](https://www.facebook.com/groups/wpspeedmatters) ### Our premium products * [FlyingPress](https://flyingpress.com) * [FlyingCDN](https://flyingcdn.com) ### Our free plugins * [Flying Pages](https://wordpress.org/plugins/flying-pages/) * [Flying Images](https://wordpress.org/plugins/nazy-load/) * [Flying Scripts](https://wordpress.org/plugins/flying-scripts/) * [Flying Analytics](https://wordpress.org/plugins/flying-analytics/) * [Flying Fonts](https://wordpress.org/plugins/flying-fonts/) #### Contributors * [Gijo Varghese – WP Speed Matters](https://wpspeedmatters.com/) * [Shay Toder](https://www.shaytoder.com/) ## 安装 1.

Visit Settings -> Flying Scripts to configure ## 常见问题 ### What are the ideal scripts to be included? Any script that is not crucial for rendering the first view or above fold contents. 3rd party scripts like tracking scripts, chat plugins, etc are ideal. ### What should I put in include keywords Any keyword inside your inline script that uniquely identifies that script. For example “fbevents.js” for Facebook Pixel, “gtag” for Google Tag Manager, “customerchat. js” for Facebook Customer Chat plugin. ### How is it different from `defer` defer tells browser to download the script when found and execute it when HTML parsing is complete. When you include a script in Flying Scripts, those scripts won’t be executed until there is a user interaction. ### What is user interaction? Events from the user like mouse hover, scroll, keyboard input, touch in mobile device, etc. ### What is timeout? Even if there is no user interaction, scripts will be executed after the specified timeout. ## 评价 ![](https://secure.gravatar.com/avatar/c668cfd7546bdf441dfb1c1a446752fb2e85b63138bf1156bbdb8d46bd2c3223? s=60&d=retro&r=g) ### 󠀁[This plugin improves metrics](https://wordpress.org/support/topic/this-plugin-improves-metrics/)󠁿 [jhonhorac](https://profiles.wordpress.org/jhonhorac/) 2026 年 6 月 14 日 1 回复 .
