How to create a HTML 5 video or audio playlist with JavaScript?

To create a HTML 5 video or audio playlist with JavaScript, we can load the next video after the current one ends.

For instance, we write

<video
  id="videoPlayer"
  src="path/of/current/video.mp4"
  autoplay
  autobuffer
  controls
/>

to add a video element.

Then we write

const nextVideo = "path/of/next/video.mp4";
const videoPlayer = document.getElementById("videoPlayer");
videoPlayer.onended = () => {
  videoPlayer.src = nextVideo;
};

to select the video element with getElementById.

And then we set its onended property to a function that updates the src attribute to the path of the next video to play.

Conclusion

To create a HTML 5 video or audio playlist with JavaScript, we can load the next video after the current one ends.

Sometimes, we want to execute a method passed as parameter to function with JavaScript.

In this article, we’ll look at how to execute a method passed as parameter to function with JavaScript.

How to execute a method passed as parameter to function with JavaScript?

To execute a method passed as parameter to function with JavaScript, we just call the function.

For instance, we write

const myFunction = (param1, callbackFunction) => {
  //...
  callbackFunction();
};

to call callbackFunction in myFunction.

Conclusion

To execute a method passed as parameter to function with JavaScript, we just call the function.

Sometimes, we want to load textures in THREE.js and JavaScript.

In this article, we’ll look at how to load textures in THREE.js and JavaScript.

How to load textures in THREE.js and JavaScript?

To load textures in THREE.js and JavaScript, we call loadTexture with a callback that’s called when the texture is loaded.

For instance, we write

const texture = THREE.ImageUtils.loadTexture("crate.gif", {}, () => {
  renderer.render(scene);
});

to call loadTexture with the path to the texture file.

And we call it with a callback that’s called after the texture is loaded as the 3rd argument.

Conclusion

To load textures in THREE.js and JavaScript, we call loadTexture with a callback that’s called when the texture is loaded.
