ionic2点击事件感觉到延迟的解决办法

In general, we recommend only adding (click) events to elements that are normally clickable. This includes <button> and <a> elements. This improves accessibility as a screen reader will be able to tell that the element is clickable.

However, you may need to add a (click) event to an element that is not normally clickable. When you do this you may experience a 300ms delay from the time you click the element to the event firing. To remove this delay, you can add the tappable attribute to your element.

<div tappable (click)="doClick()">I am clickable!</div>

一般来说，我们建议您只向通常可点击的元素添加（点击）事件。 这包括<button>和<a>元素。 这提高了可访问性，因为屏幕阅读器将能够告诉该元素是可点击的。

但是，您可能需要向通常不可点击的元素添加（点击）事件。 执行此操作时，您可能会遇到从点击元素到事件触发的300毫秒延迟。 要删除此延迟，可以将tappable属性添加到元素。
