元素 接口的 onfullscreenchange property is an event handler for the fullscreenchange event that is fired when the element has transitioned into or out of full-screen mode.

句法

targetDocument.onfullscreenchange = fullscreenChangeHandler;

值

An event handler for the fullscreenchange event, indicating that the element has changed in or out of full-screen mode.

范例

This example establishes a fullscreenchange event handler, handleFullscreenChange() . This function determines which element it was called on by checking the value of event.target , then compares the document's fullscreenElement value to the element to see if they're the same node.

This gives us a value, isFullscreen , which we pass into a function called adjustMyControls() , which we imagine to be a function that makes adjustments to the app's user interface to present itself optimally when it's in full-screen mode versus being displayed in a window.

function toggleFullscreen() {
  let elem = document.querySelector("video");
  elem.onfullscreenchange = handleFullscreenChange;
  if (!document.fullscreenElement) {
    elem.requestFullscreen().then({}).catch(err => {
      alert(`Error attempting to enable full-screen mode: ${err.message} (${err.name})`);
    });
  } else {
    document.exitFullscreen();
  }
}
function handleFullscreenChange(event) {
  let elem = event.target;
  let isFullscreen = document.fullscreenElement === elem;
  adjustMyControls(isFullscreen);
}
