preload.js的写法例子

以下是一个preload.js的写法例子：

const manifest = [
  { src: "images/background.jpg", id: "background" },
  { src: "images/logo.png", id: "logo" },
  { src: "sounds/music.mp3", id: "music" }
];

const loader = new createjs.LoadQueue();
loader.loadManifest(manifest);
loader.on("complete", handleComplete);

function handleComplete() {
  const background = loader.getResult("background");
  const logo = loader.getResult("logo");
  const music = loader.getResult("music");
  // do something with the loaded assets
}

请注意，这只是一个例子，实际上preload.js的写法可以根据具体需求进行调整。
