Your browser does not support the video tag.
However, it should be noted that automatically playing videos is often accompanied by user experience considerations. In particular, videos with audio may play sounds at inappropriate times, affecting the user experience. Another commonly used attribute for this purpose is muted, which can be set to true to mute the video to satisfy autoplay policy restrictions.
In order to comply with browser policies and improve user experience, setting the video to automatically play after muting is a highly recommended practice:
Your browser does not support the video tag.
In some cases, you may need more control over the automatic playback of videos, which can be achieved with the help of JavaScript. By listening to the page load (DOMContentLoaded) event or video load (loadedmetadata) event, you can control the video playback behavior more flexibly.
The video starts playing when the entire page DOM is loaded. This is suitable for ensuring that other elements of the page are ready:
document.addEventListener(DOMContentLoaded, function() {
var myVideo = document.getElementById(myVideo);
myVideo.play();
});
Playback starts after the video metadata has been loaded, which ensures that the video's duration and dimensions have been loaded:
var myVideo = document.getElementById(myVideo);
myVideo.addEventListener(loadedmetadata, function() {
this.play();
});
When implementing autoplay videos, you must consider user experience and satisfy browser autoplay policies. In recent years, in order to protect user experience, mainstream browsers such as Google and Firefox have implemented strict policies on auto-playing videos. In short, most browsers allow videos with silence to play automatically, while videos with sound require user interaction to play.
In order not to disturb users, it is recommended that when designing an auto-playing video, you first consider setting the video to mute and provide obvious playback control buttons so that users can control the playback of the video at any time. In addition, you can also consider the use of video covers to give users an expected visual presentation before clicking to play.
Autoplay policies vary slightly across browsers and platforms, but the common thread is the protection of the user experience. When implementing the autoplay function, developers should always pay attention to the latest policy changes of the target browser and test as much as possible to ensure compatibility. For situations where automatic playback is not supported, there should be appropriate alternatives, such as using a play button to prompt the user for manual playback.
Through the above method, you can implement the auto-play function of embedded videos in HTML5 pages while ensuring a good user experience. But remember, always be user-centered and follow browser policies to achieve the best interaction.

How to automatically play videos through JavaScript? You can use JavaScript to control the video's playback and start playing automatically after the page loads. The sample code is as follows:
window.onload = function() { var video = document.getElementById(myVideo); video.play();};In the above code you need to
How to deal with browser restrictions on autoplay? Some modern browsers will restrict auto-play audio and video. To ensure the availability of auto-play, you can consider the following methods: Before embedding the video, first play a silent video to initiate user media interaction. Hide the video and show a play button that plays the video when the user clicks the button. Consider using the autoplay attribute in browsers that support autoplay, and in browsers that don't support it, display a prompt asking the user to manually click play. Consider using an adaptive player library such as Video.js or Plyr, which provides better browser compatibility and autoplay handling.I hope this tutorial by the editor of Downcodes can help you better understand and apply the HTML5 video autoplay function. Remember to always prioritize user experience and browser compatibility during development to create a better web application.
