我正在尝试做三件事:
-
防止在移动上自动聚焦输入
-
阻止网页在移动上移动
-
允许在<ul>
To prevent auto focus of input on mobile: a) add readonly to input tags b) add <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" /> To prevent the webpage from moving on mobile: a) function preventBehavior(e) { e.preventDefault(); }; document.addEventListener("touchmove", preventBehavior, {passive: false}); To allow touch movement on <ul> on mobile: a) function allowBehavior(e){ e.stopPropagation() } let tp = document.getElementsByClassName('ui-timepicker-viewport') tp[0].addEventListener("touchmove", allowBehavior);
这一切似乎在大多数时候都有效。偶尔,当滚动<李>元素,整个屏幕都会移动。我该如何阻止这种行为?
注意:js timepicker库使用class="timepicker"的输入,该库放置带有li元素的下拉列表。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";
