AudioContext.state
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
AudioContext的 state 属性是只读的，返回 AudioContext 的当前状态。
语法
js
var audioCtx = new AudioContext();
var myState = audioCtx.state;
返回值
DOMString，可能的值如下：
suspended: audio context 被阻塞了 (用AudioContext.suspend()方法)running: audio context 正常运行closed: audio context 被关闭了 (用AudioContext.close()方法)
例子
下面这段代码是AudioContext states demo (直接运行) 中的，其中AudioContext.onstatechange处理器会在每次当前状态发生变化时把它输出到控制台。
js
audioCtx.onstatechange = function () {
console.log(audioCtx.state);
};
