触摸两个dom元素上的事件? [英] Touch events over two dom elements?

问题描述

我有两个相邻的dom元素.

I have two dom elements right next to one another.

在触摸事件期间，我希望能够在每个元素上滑动.正如我所做的那样，根据我所处的元素，我希望发生不同的事情.

During a touch event I want to be able to slide over each element. As I do, depending on what element i'm on I want different things to happen.

这看起来像什么?

由于触摸下降，因此新的touchstart事件不会在它们滑动到新元素时触发.

Since the touch is down a new touchstart event doesn't fire as they slide to the new element.

谢谢！

这是实际代码

ul
   li 1
   li 2
   li 3

我想对每个项目进行一次恒定的touchmove事件，而我真正需要的是它能够知道当前li

I want to carry a constant touchmove event over each item and all i really need it to be able to know the index of the current li

现在我正在尝试:

$('ul').live 'touchmove', (event) ->
   element = document.elementFromPoint(event.clientX, event.clientY)
   #now i need the index of this element somehow

推荐答案

element = document.elementFromPoint(event.pageX, event.pageY)

pageX和pageY ，而不是clientX和clientY

pageX and pageY not clientX and clientY

很难查看这些事件对象中的触摸事件，因为移动Safari控制台是如此原始.

It's hard to look into these event objects for touch events because the mobile Safari console is so freaking primitive.
