ng.getListeners
Retrieves a list of event listeners associated with a DOM element. The list does include host listeners, but it does not include event listeners defined outside of the Angular context (e.g. through addEventListener).
ng.getListeners(element: Element): Listener[]
参数
element | Element | Element for which the DOM listeners should be retrieved. |
返回值
Listener[]: Array of event listeners on the DOM element.
使用说明
Given the following DOM structure:
<my-app>
<div (click)="doSomething()"></div>
</my-app>
Calling getListeners on <div> will return an object that looks as follows:
{
name: 'click',
element: <div>,
callback: () => doSomething(),
useCapture: false
}
