目前,我正尝试通过javascript全屏显示图像。 (全屏API-https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API)
JavaScript代码:
var enterFullscreen = function(el) {
if(el.requestFullscreen) {
el.requestFullscreen();
} else if(el.msRequestFullscreen) {
el.msRequestFullscreen();
} else if(el.mozRequestFullScreen) {
el.mozRequestFullScreen();
} else if(el.webkitRequestFullscreen) {
el.webkitRequestFullscreen();
} else {
noFullscreenSupport();
}
var exitFullscreen = function() {
if(document.exitFullscreen) {
document.exitFullscreen();
} else if(document.msExitFullscreen) {
document.msExitFullscreen();
} else if(document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if(document.webkitExitFullscreen) {
document.webkitExitFullscreen();
} else {
noFullscreenSupport();
}
var initFullScreenButtons = function() {
$('.fullScreenButton').each(function(e) {
$(this).bind('click', function() {
if((window.innerWidth === screen.width && window.innerHeight === screen.height) || (window.fullScreen)) {
exitFullscreen();
} else {
enterFullscreen(document.documentElement);
}
});
});
我获得了全屏按钮,并将它们绑定到一个点击事件,该事件会调用该函数进入全屏状态。

结果是图像有时以全屏或半全屏显示,其中页面背景以浏览器任务栏和Windows任务栏的宽度/高度显示在页面底部。
此外,当我尝试使用浏览器的开发人员工具时,视觉错误便消失了。

我找到了解决问题的方法。不必传递document.documentElement
(根元素),我必须传递document.body
(body-element)到函数。
