DevExtreme jQuery/JS - Handle the Value Change Event
To process a new Switch value, you need to handle the value change event. If the handling function is not going to be changed during the lifetime of the widget, assign it to the onValueChanged option when you configure the widget.
JavaScript
$(function() {
$("#switchContainer").dxSwitch({
onValueChanged: function (e) {
var previousValue = e.previousValue;
var newValue = e.value;
// Event handling commands go here
}
});
});If you are going to change event handlers at runtime, or if you need to attach several handlers to the value change event, subscribe to this event using the on(eventName, eventHandler) method.
JavaScript
var valueChangedHandler1 = function (e) {
var previousValue = e.previousValue;
var newValue = e.value;
// First handler of the "valueChanged" event
};
var valueChangedHandler2 = function (e) {
var previousValue = e.previousValue;
var newValue = e.value;
// Second handler of the "valueChanged" event
};
$("#switchContainer").dxSwitch("instance")
.on("valueChanged", valueChangedHandler1)
.on("valueChanged", valueChangedHandler2);See Also
