addPromise = worklet.addModule(moduleURL, options);

范例

AudioWorklet example

const audioCtx = new AudioContext();
const audioWorklet = audioCtx.audioWorklet;
await audioWorklet.addModule('modules/bypassFilter.js', {
  credentials: 'omit',
});
						

PaintWorklet example

CSS.paintWorklet.addModule('https://mdn.github.io/houdini-examples/cssPaint/intro/worklets/hilite.js');
						

一旦 paintWorklet is included, the CSS paint() function can be used to include the image created by the worklet:

@supports (background-image: paint(id)) {
  h1 {
      background-image: paint(hollowHighlights, filled, 3px);
  }
}
