IFrame Height

The client receives the height of the iframe every time the height changes

Example

{
    "type": "IFRAME_SIZE",
    "height": 1850
}

Example of Javascript code to get the message

const iframe = document.getElementById("ifrContent");
window.addEventListener("message", (event) => {
  if (event.data?.type === "IFRAME_SIZE") {
    iframe.style.height = `${event.data.height}px`;
  }
});
