Is there any way to create Audio mute/unmute button in articulate by using javascript?

Hi Matthew,

thanks for your reply.

i will check.

Hi Anitha,

have you had a look at the sample file I uploaded in the threat Matthew referenced above? You should be able to create a single mute/unmute toggle button for multiple audios with that and the script I posted later in that thread:

var allAudios = document.getElementsByTagName('audio');

if (allAudios[0].volume > 0) {
 for (var a = 0; a < allAudios.length; a++) {
 allAudios[a].volume = 0;
 }
 } else {
 for (var a = 0; a < allAudios.length; a++) {
 allAudios[a].volume = 1.0;
 }
}

For javascript integration in general, there's an introduction by Articulate: https://articulate.com/support/article/javascript-best-practices-and-examples

For Flash there's the mutetoggler script you can find here: https://community.articulate.com/discussions/articulate-storyline/javascript-to-mute-audio#95681

sadly, there's no universal solution

Hello Swapnil,

This thread is a bit dated and I'm not sure if David is still subscribed here. You are certainly welcome to reach out to the user directly via the 'Contact Me' option on the user profile if you do not hear back soon.

Swapnil, which version of Storyline are you using?

Hi Anderson,

Sudhakar, check out the article below for instructions. Make sure you use the code for Storyline 3 and not Storyline 2. Let me know if you need any more help.
