javascript – 音量关闭在html5视频ipad 2中不起作用

概述音量关闭在 html5视频ipad 2中不起作用. player = document.getElementById(element_id);if (player.muted){ player.muted = false; player.volume = 1; //player.volume(1);}else{ player.muted = true; 音量关闭在 html5视频ipad 2中不起作用.

player = document.getElementByID(element_ID);if (player.muted){    player.muted = false;    player.volume = 1;    //player.volume(1);}else{    player.muted = true;    player.volume = 0;    //player.volume(0);}

解决方法 我担心iOS不允许使用JavaScript更改音量.来自Apple的 documentation(重点是我的)：

On the desktop,you can set and read the volume property of an or element. This allows you to set the element’s audio volume relative to the computer’s current volume setting. A value of 1 plays sound at the normal level. A value of 0 silences the audio. Values between 0 and 1 attenuate the audio.

This volume adjustment can be useful,because it allows the user to mute a game,for example,while still Listening to music on the computer.

On iOS devices,the audio level is always under the user’s physical control. The volume property is not settable in JavaScript. Reading the volume property always returns 1.

没有提到静音属性,但实验表明它也无法改变：
