async function doTransition() {
let transition = document.createDocumentTransition();
// Specify offered elements. The tag below is used to refer
// to the generated pseudo elemends in script/CSS.
document.querySelector(".old-message").style.pageTransitionTag = "message";
// The start() call triggers an async operation to capture
// snapshots for the offered elements,
await transition.start(async () => {
// This callback is invoked by the browser when the capture
// finishes and the DOM can be switched to the new state.
// No frames are rendered until this callback returns.
// Asynchronously load the new page.
await coolFramework.changeTheDOMToPageB();
// Clear the old message if that element is still in the page
document.querySelector(".old-message").style.pageTransitionTag = "";
// Set new message as the shared element 'message'
document.querySelector(".new-message").style.pageTransitionTag = "message";
// Set up animations using WA-API on the next frame.
requestAnimationFrame(() => {
document.documentElement.animate(keyframes, {
...animationOptions,
pseudoElement: "::page-transition-container(message)",
});
});
// Note that when this callback finishes, the animations will start with the tagged elements.
});
