前端：横向滚动条，拖动进行左右滚动（含隐藏滚动条）

效果：

代码：

单独封装一个addMouseEvent.ts文件

TypeScript 复制代码

// 添加鼠标移动事件

export const addMouseEvent = (el: string) => {
	let container = document.querySelector(el) as HTMLDivElement;
	let isMouseDown = false;
	let startX = 0;
	let scrollLeft = 0;

	// 鼠标按下事件
	const onMouseDown = (e: MouseEvent) => {
		isMouseDown = true;
		startX = e.pageX - container.offsetLeft;
		scrollLeft = container.scrollLeft;
	};
	// 鼠标移动事件
	const onMouseMove = (e: MouseEvent) => {
		if (!isMouseDown) return;
		e.preventDefault();
		let x = e.pageX - container.offsetLeft;
		let walk = (x - startX) * 1; // 调整滚动速度
		container.scrollLeft = scrollLeft - walk;
	};
	// 鼠标抬起事件
	const onMouseUp = () => {
		isMouseDown = false;
	};
	// 鼠标离开事件
	const onMouseLeave = () => {
		isMouseDown = false;
	};

	container.addEventListener("mousedown", function (e) {
		onMouseDown(e);
	});
	container.addEventListener("mouseleave", function () {
		onMouseLeave();
	});
	container.addEventListener("mouseup", function () {
		onMouseUp();
	});
	container.addEventListener("mousemove", function (e) {
		onMouseMove(e);
	});

	const removeEventListeners = () => {
		container.removeEventListener("mousedown", onMouseDown);
		container.removeEventListener("mouseleave", onMouseLeave);
		container.removeEventListener("mouseup", onMouseUp);
		container.removeEventListener("mousemove", onMouseMove);
	};
	return removeEventListeners;
};

在页面中使用：

.device-list是要执行滑动的dom元素

TypeScript 复制代码

onMounted(() => {
	nextTick(() => {
		mouseLeaveEvent.value = addMouseEvent(".device-list");
	});
});
onBeforeUnmount(() => {
	mouseLeaveEvent.value && mouseLeaveEvent.value();
});

隐藏横向滚动条：

css 复制代码

::-webkit-scrollbar {
	/* 隐藏Webkit浏览器的滚动条 */
	display: none;
}
