Android webview touchmove错误

Question

我正在开发一个 Android WebView 应用程序，由于某种原因，“touchmove”事件拒绝触发。它在桌面浏览器上运行良好。我该如何解决？也不适用于 android 模拟器。

document.body.addEventListener("touchstart", function (e) {
    console.log("touchstart", e);
    e.preventDefault();
    e.stopPropagation();
});
document.body.addEventListener("touchmove", function (e) {
    console.log("touchmove", e); // <--- refuses to fire
    e.preventDefault();
    e.stopPropagation();
});
document.body.addEventListener("touchend", function (e) {
    console.log("touchend", e);
    e.preventDefault();
    e.stopPropagation();
});

Answer 1

您可能需要像这样解决它:

var onTouchEnd = function(){
  console.log("touch end");
}
document.addEventListener("touchstart", onTouchEnd);
document.addEventListener("touchmove", onTouchEnd);
document.addEventListener("touchend", onTouchEnd);

或

试着这样安慰它

var onTouchEnd = function(){
  console.log("touch end");
  var touch = event.changeTouches[0];
  console.log("touch", touch);
}
document.addEventListener("touchstart", onTouchEnd);
document.addEventListener("touchmove", onTouchEnd);
document.addEventListener("touchend", onTouchEnd);
