在JavaScript中，iPhone浏览器是否有启动滚动事件？

Question

I would like to detect when a user starts to scroll a webpage in the iPhone web browser. Is this possible?

Answer 1

Use an onscroll event as usual and delete it when the user scrolled for the first time.

window.onscroll = function() {
    alert("I saw that!");
    window.onscroll = null;
}
