禁止 IOS 橡皮筋效果
SKILL·NULL · 2024-12-20 · via 博客园 - SKILL·NULL

方法一:

首先,在拖动 div 时,判断当前容器 div 是否有滚动条,如果没有,则禁止整个 div 拖动,例:

const list_dom: any = document.querySelector(".list");
list_dom.addEventListener("touchmove",(ev) => {
  if (list_dom.scrollHeight <= list_dom.clientHeight &&list_dom.offsetHeight <= list_dom.clientHeight) {
    ev.preventDefault();
  }
},{ passive: false });

注:上述方法仅适用于 div 内没有其他内容滚动情形!如果内层有其他 div 滚动,则需要监听当前滑动区域是否在内层滚动 div 上,如果在对应滚动 div 上,则不调用 ev.preventDefault() 方法,否则则调用。

在配置上述方法同时,对相应存在滚动的 div 设置 css 属性:

overscroll-behavior: none;

使临近滚动区域不受到滚动链影响,滚动到边界后不会带动外层滚动。

方法二:

export const getClientHeight = () => {
	return (
		window.innerHeight ||
		document.documentElement.clientHeight ||
		document.body.clientHeight
	);
};

/*
 * @Function 处理touchmove, 将滚动条拖到边缘的时候,禁止橡皮筋效果
 */
class HandleTouchMove {
	startX;
	startY;

	constructor() {
		this.startX = 0;
		this.startY = 0;
		this.listenTouchstart = this.listenTouchstart.bind(this);
		this.listenTouchmove = this.listenTouchmove.bind(this);
	}

	listenTouchstart = (ev: any) => {
		this.startX = ev.changedTouches[0].pageX;
		this.startY = ev.changedTouches[0].pageY;
	};

	listenTouchmove = (ev: any, _dom: any) => {
		const dom = document.querySelector(_dom);
		const moveEndX = ev.changedTouches[0].pageX;
		const moveEndY = ev.changedTouches[0].pageY;
		const moveX = moveEndX - this.startX;
		const moveY = moveEndY - this.startY;
		if (Math.abs(moveX) > Math.abs(moveY) && moveX > 0) {
			// 向右拖拽
			if (dom?.scrollLeft === 0) {
				ev.cancelable && ev.preventDefault();
			}
		}
		if (Math.abs(moveX) > Math.abs(moveY) && moveX < 0) {
			// 向左拖拽
			if (
				dom?.scrollLeft + dom?.offsetWidth === dom?.scrollWidth &&
				dom?.scrollLeft + dom?.clientWidth === dom?.scrollWidth
			) {
				ev.cancelable && ev.preventDefault();
			}
		}
		if (Math.abs(moveY) > Math.abs(moveX) && moveY > 0) {
			// 向下拖拽
			if (dom?.scrollTop === 0) {
				ev.cancelable && ev.preventDefault();
			}
		}
		if (Math.abs(moveY) > Math.abs(moveX) && moveY < 0) {
			// 向上拖拽
			if (
				dom?.scrollHeight - (dom?.scrollTop + dom?.offsetHeight) <= 1 &&
				dom?.scrollHeight - (dom?.scrollTop + dom?.clientHeight) <= 1
			) {
				ev.cancelable && ev.preventDefault();
                                ev.stopPropagation();
			}
		}
	};
}

export const handleTouchmove = new HandleTouchMove();

调用示例:

<template>
	<div class="wrap" :style="{ height: client_height }">
		<div
			class="content"
			@touchstart="handleTouchmove.listenTouchstart"
			@touchmove="
				(ev) => handleTouchmove.listenTouchmove(ev, 'content')
			">
			<div style="height: 1000px">132</div>
		</div>
	</div>
</template>

<script lang="ts" setup>
	import { getClientHeight, handleTouchmove } from "@/components/Common/utils";
	import { onMounted, ref } from "vue";

	const client_height: any = ref("100vh");

	onMounted(() => {
		client_height.value = getClientHeight() + "px";
	});
</script>

<style lang="scss" scoped>
	.wrap {
		width: 100%;

		.content {
			height: 100%;
			overflow-y: auto;
			overscroll-behavior: none;
		}
	}

	@supports (padding-bottom: env(safe-area-inset-bottom)) or
		(padding-bottom: constant(safe-area-inset-bottom)) {
		.content {
			padding-bottom: constant(safe-area-inset-bottom); /* 兼容 iOS < 11.2 */
			padding-bottom: env(safe-area-inset-bottom); /* 兼容 iOS >= 11.2 */
		}
	}

	@supports not (padding-bottom: env(safe-area-inset-bottom)) {
		.content {
			padding-bottom: 20px;
		}
	}

	@supports not (padding-bottom: constant(safe-area-inset-bottom)) {
		.content {
			padding-bottom: 20px;
		}
	}
</style>
