js设置浏览器全屏，无地址栏

html:

<p>
<button id="view-fullscreen">全屏</button>
<button id="cancel-fullscreen">退出</button>
</p>

js:

// JavaScript Document
(function () {
var viewFullScreen = document.getElementById("view-fullscreen");
if (viewFullScreen) {
viewFullScreen.addEventListener("click", function () {
var docElm = document.documentElement;
if (docElm.requestFullscreen) {
docElm.requestFullscreen();
}
else if (docElm.msRequestFullscreen) {
docElm.msRequestFullscreen();
}
else if (docElm.mozRequestFullScreen) {
docElm.mozRequestFullScreen();
}
else if (docElm.webkitRequestFullScreen) {
docElm.webkitRequestFullScreen();
}
}, false);
}

var cancelFullScreen = document.getElementById("cancel-fullscreen");
if (cancelFullScreen) {
cancelFullScreen.addEventListener("click", function () {
if (document.exitFullscreen) {
document.exitFullscreen();
}
else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
}, false);
}
})();

不能使用模拟点击操作的方式，因为浏览器的保护机制，只能通过手动点击的方式触发
