问题描述

在iPad等触控设备上(或镀铬中的移动仿真模式)。在主体上跟踪 touchmove 事件并从dom touchmove 中删除​​一个元素(在touchstart上启动)从身体停止触发的事件。

On touch devices such as iPad (or mobile emulaton mode in chrome). When tracking touchmove event on body and removing an element (on which touchstart started) from dom touchmove events from body stops triggering.

我做了一个示例

有没有 touchmove 的方法是否在删除子元素后继续工作?

Is there any way for the touchmove continue working even after the child element is removed?

推荐答案

touchend 事件为止。
触发 touchstart 事件的视图的伪代码如下所示:

I fixed this issue by caching the element until touchend event is emitted.The pseudo code for the view that triggered the touchstart event would look something like this:

view.remove = function () {
  if (didViewStartTouchEvents) {
    var _this = this;
    this.hideElement(); // display: none, opacity: 0, etc
    elementCache.appendChild(this); //append this element to some other place like body. Not needed but might be handy depending on situation
    document.body.addEventListener('touchend', function () {
      _this.didViewStartTouchEvents = false;
      _this.remove();
    });
  } else {
    // regular remove & cleanup
  }
}
