我需要preform在我的应用程序特定的操作，如果用户presses并持有几秒钟的一个按钮，如果用户的延迟耗尽之前删除按钮的手指，然后这一行动将被取消。我使用的preSS'ontouchstart事件。

I'm need to preform a specific action in my app if the user presses and holds a button for a few second, if the user removes his finger from the button before the delay runs out, then this action will be cancelled. I use 'ontouchstart' event for the press.

有什么办法，我可以做到这一点使用HTML和JavaScript？

Is there any way i can achieve this using html and javascript?

感谢。
