Events

changeCustomEvent

This event is triggered when the selection is changed.

  • Bubbles Yes
  • Cancelable No
  • Interface CustomEvent
  • Event handler property onChange

Arguments

evCustomEvent
ev.detailObject
ev.detail.label - The label of the new selected item.
ev.detail.oldLabel - The label of the item that was previously selected before the event was triggered.
ev.detail.oldValue - The value of the item that was previously selected before the event was triggered.
ev.detail.value - The value of the new selected item.

Methods

isDefaultPrevented

Returns true if the event was prevented by any of its subscribers.

Returns

boolean true if the default action was prevented. Otherwise, returns false.

preventDefault

The preventDefault() method prevents the default action for a specified event. In this way, the source component suppresses the built-in behavior that follows the event.

stopPropagation

The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases.

Example

Set up the event handler of change event. 

const input = document.querySelector('smart-input');
input.addEventListener('change', function (event) {
    const detail = event.detail,
        label = detail.label,
        oldLabel = detail.oldLabel,
        oldValue = detail.oldValue,
        value = detail.value;

	// event handling code goes here.
})
