这是我指的API:https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API
至此,我已经尝试过了:
Modernizr拥有Modernizr.fullscreen
的东西,但我不希望使用另一个库来完成看似简单的任务。
因此,毕竟Modernizr确实使用JS来弄清楚了,对了,我正在挖掘Modernizr的源代码以尝试看看它们是如何做到的,对吗?但是到目前为止,我在其源代码中发现的有关全屏API的全部就是这个文件(Modernizr / feature-detects / fullscreen-api.js)
/*!
{
"name": "Fullscreen API",
"property": "fullscreen",
"caniuse": "fullscreen",
"notes": [{
"name": "MDN Docs",
"href": "https://developer.mozilla.org/en/API/Fullscreen"
}],
"polyfills": ["screenfulljs"],
"builderAliases": ["fullscreen_api"]
}

/* DOC

*/
define(['Modernizr', 'prefixed'], function(Modernizr, prefixed) {
// github.com/Modernizr/Modernizr/issues/739
Modernizr.addTest('fullscreen', !!(prefixed('exitFullscreen', document, false) || prefixed('cancelFullScreen', document, false)));
});
...而且我不太了解该代码。
答案 0 :(得分:0)
以下代码段似乎是最佳解决方案:
const fullScreenAvailable = document.fullscreenEnabled ||
document.mozFullscreenEnabled ||
document.webkitFullscreenEnabled ||
document.msFullscreenEnabled
