阅读更多关于 How to control Windows system volume using JScript or VBScript?

I want to control the volume of my Windows system from a JScript or VBScript script. Any ideas? Also, can I unmute the system volume if it is muted? Helen To mute or unmute the system volume, you can simulate the Mute key press using the WshShell.SendKeys method: var oShell = new ActiveXObject("WScript.Shell"); oShell.SendKeys(Chr(&HAD)); As for changing the volume level from a script, there's a solution that involves some Windows automation, such as launching the System Volume applet and simulating the appropriate keyboard shortcuts in it, but I don't think it's reliable.

问题 I'd like to make a mute/unmute button in jQuery. I've done some searching on Stackoverflow and this is what I managed to do so far: $("video").prop('muted', true); $("#mute-video").click( function (){ if( $("video").prop('muted', true) ) { $("video").prop('muted', false); } else { $("video").prop('muted', true); } }); but for some reason it's only able to unmute, not to mute back.

Trying to write a PowerShell cmdlet that will mute the sound at start, unless already muted, and un-mute it at the end (only if it wasn't muted to begin with). Couldn't find any PoweShell or WMI object I could use.
