Question

当用户滚动collection-repeat长列表时，我在离子应用中收到此错误。

ignored attempt to cancel a touchstart event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.

知道这是什么吗？

<div class="scrollContainer">

Answer 1

对我来说，在文件vendor.js中注释了这些行

ToggleGesture.prototype.onDragStart = function (ev) {
    /*ev.preventDefault();*/
    this.toggle._onDragStart(Object(__WEBPACK_IMPORTED_MODULE_2__util_dom__["f" /* pointerCoord */])(ev).x);
};
ToggleGesture.prototype.onDragMove = function (ev) {
    /*ev.preventDefault();*/
    this.toggle._onDragMove(Object(__WEBPACK_IMPORTED_MODULE_2__util_dom__["f" /* pointerCoord */])(ev).x);
};
ToggleGesture.prototype.onDragEnd = function (ev) {
    /*ev.preventDefault();*/
    this.toggle._onDragEnd(Object(__WEBPACK_IMPORTED_MODULE_2__util_dom__["f" /* pointerCoord */])(ev).x);
};

只需转到 ion-datetime 3-ios.entry.js 并评论第 1383 行：

detail.event.preventDefault();

您将摆脱错误：
