我想做三件事：

防止输入在移动

上的自动聚焦

阻止网页在移动

上移动

允许触摸移动

为防止输入自动聚焦于移动: a)添加只读输入标签b)添加以防止网页在移动: a)函数preventBehavior(e) { e.preventDefault()；}；document.addEventListener(“触摸移动”，preventBehavior，{被动: false})；在移动平台上允许触摸移动: a)函数allowBehavior(e){ e.stopPropagation() } let = allowBehavior); tp.addEventListener(“触摸移动”，allowBehavior)；)

这一切似乎大部分时间都起作用。偶尔，当滚动这些元素时，整个屏幕会移动。我怎么才能阻止这种行为？

注意:带有class=' timepicker‘的输入由js时间选择器库使用，该库在li元素中放置下拉列表。请参阅链接并在移动设备上使用以复制行为。

尝试使用css：

.ui-timepicker-viewport {
  overscroll-behavior: none
}

body {
  overscroll-behavior: none
}

或者javascript：

[...document.getElementsByClassName('ui-timepicker-viewport')].forEach(element => element.style.overscrollBehavior = "none");
document.body.style.overscrollBehavior = "none";
