我就看了一个函数的源码： export function yd_browser_openFullscreen(element) { if (element.requestFullscreen) { element.requestFullscreen(); } else if (element.mozRequestFullScreen) { element.mozRequestFullScreen(); } else if (element.msRequestFullscreen) { element.msRequestFullscreen(); } else if (element.webkitRequestFullscreen) { element.webkitRequestFullScreen(); } } 几位大佬就告诉你 RequestFullScreen 了，名字还叫 openFullscreen 。。。。
