<button onclick="launchFullscreen(document.documentElement);">启动全屏</button>

function launchFullscreen(element) {
    if (element.requestFullscreen) {
        element.requestFullscreen();
    } else if (element.mozRequestFullScreen) {
        element.mozRequestFullScreen();
    } else if (element.webkitRequestFullscreen) {
        element.webkitRequestFullscreen();
    } else if (element.msRequestFullscreen) {
        element.msRequestFullscreen();
    }
}
