Element.onfullscreenerror - Web API 接口参考 编辑

Element 接口的 onfullscreenerror 属性是在Element 过渡到或退出全屏模式发生错误后处理事件fullscreenerror的事件处理程序。

语法

targetElement.onfullscreenerror = fullscreenErrorHandler;

值

一个处理事件fullscreenerror的事件处理程序.

示例

本示例尝试不从用户发起的事件(如点击事件click或键盘事件keypress)处理程序来触发全屏，由于全屏模式只允许由用户主动输入触发，因此该操作会发生错误，从而导致Element会触发fullscreenerror事件传递给错误处理程序

let elem = document.querySelector("video")}}

elem.onfullscreenerror = function ( event ) {
  displayWarning("Unable to switch into full-screen mode.");
};

//....

elem.requestFullscreen();
