I have tried the below code for getting checked value of toggle switch button. But I am unable to find the checked property of toggle switch in JavaScript method.
.js:
var yammerpt = document.getElementById("toggleSwitch").winControl;
.html:
<div id="toggleSwitch" data-win-control="WinJS.UI.ToggleSwitch" data-win-options="{labelOn:'Post to Yammer', labelOff:'Post to Yammer', checked:true}">
The checked
property is what you're looking for.
var yammerpt = document.getElementById("toggleSwitch").winControl; //here you get the control itself
var checked = yammerpt.checked;
