document.getElementById('myButton').addEventListener('click', function(event) { event.stopPropagation(); alert('Button was clicked!'); }); 3. 性能问题 原因: 大量元素绑定事件可能导致性能下降。 解决方法: 使用事件委托,将事件监听器绑定到父元素上。

To override the default double-click handling, set userActions.doubleClick to a function which accepts a dblclick event: function myDoubleClickHandler(event) = { // `this` is the player in this context this.pause(); }; videojs('my-player', { userActions: { doubleClick: myDoubleClickHandler...
@dblclick="showEditForm(row,$event)" @click="rowSelect(row,$event)" > 这样做,我会在双击时触发 3 个事件。两个点击事件,最后一个 dblclick。由于 click 事件首先触发,有没有办法(没有将 click 事件推迟固定数量的 ms)来停止在双击时传播 click 事件?
