vue实现鼠标滚轮控制页面横向滑动
先看效果

1.首先创建一个xScroll.vue组件
<template><div class="main" v-size-ob="mainSize"><div class="v-scroll"><div class="content"><slot></slot></div></div></div>
</template>
<script setup lang="ts"></script>
<style scoped lang="less">
.main {width: 100%;height: 100%;
}
</style>
在页面中使用
<div class="zlcXScroll"><xScroll><div class="imgs"><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div><div><img src="https://picsum.photos/200/300" alt="" /></div></div></xScroll></div>效果：
将容器内的内容横向排列
.zlcXScroll {width: 100%;height: 300px;.imgs {display: flex;flex-direction: row;align-items: center;img {margin-right: 10px;}}}效果：(目前需要按住shift再滑动滚轮)
2.利用盒子纵向滚动条默认不需要shift键
绿色盒子就是v-scroll,v-scroll网上转90之前，需要将内容(照片盒子content)向下旋转90°
3.获取红色盒子的宽高，赋值给绿色盒子的高宽
<template><div class="main" v-size-ob="mainSize"><div class="v-scroll"><div class="content"><slot></slot></div></div></div>
</template>
<script setup lang="ts">
import { reactive } from "vue";
let mainMes = reactive({w: 0,h: 0,
});
interface Eobj {width: number;height: number;
}
let mainSize = (e: Eobj) => {let { width, height } = e;mainMes.w = width;mainMes.h = height;
};
</script>
<style scoped lang="less">
.main {width: 100%;height: 100%;outline: 1px solid red;.v-scroll {outline: 1px solid rgb(17, 0, 255);--w: calc(v-bind(mainMes.w) * 1px);--h: calc(v-bind(mainMes.h) * 1px);width: var(--h);height: var(--w);.content{height: var(--h);}}
}
</style>
4.将content盒子向下旋转90°
按照左上角为中心，直接旋转，会跑到最大容器外面去，可以往右移一点距离(红色容器的高度)，然后再旋转
<template><div class="main" v-size-ob="mainSize"><div class="v-scroll"><div class="content"><slot></slot></div></div></div>
</template>
<script setup lang="ts">
import { reactive } from "vue";
let mainMes = reactive({w: 0,h: 0,
});
interface Eobj {width: number;height: number;
}
let mainSize = (e: Eobj) => {let { width, height } = e;mainMes.w = width;mainMes.h = height;
};
</script>
<style scoped lang="less">
.main {width: 100%;height: 100%;outline: 1px solid red;.v-scroll {outline: 1px solid rgb(17, 0, 255);--w: calc(v-bind(mainMes.w) * 1px);--h: calc(v-bind(mainMes.h) * 1px);width: var(--h);height: var(--w);position: relative;.content {height: var(--h);position: absolute;left: var(--h);transform-origin: left top;transform: rotate(90deg);}}
}
</style>
效果：
5.content旋转完后，再将v-scroll向上旋转90°即可
<template><div class="main" v-size-ob="mainSize"><div class="v-scroll"><div class="content"><slot></slot></div></div></div>
</template>
<script setup lang="ts">
import { reactive } from "vue";
let mainMes = reactive({w: 0,h: 0,
});
interface Eobj {width: number;height: number;
}
let mainSize = (e: Eobj) => {let { width, height } = e;mainMes.w = width;mainMes.h = height;
};
</script>
<style scoped lang="less">
.main {width: 100%;height: 100%;outline: 1px solid red;.v-scroll {outline: 1px solid rgb(17, 0, 255);--w: calc(v-bind(mainMes.w) * 1px);--h: calc(v-bind(mainMes.h) * 1px);width: var(--h);height: var(--w);position: relative;overflow: hidden scroll;transform-origin: 0 0;transform: translateY(var(--h)) rotate(-90deg);&::-webkit-scrollbar {width: 0;height: 0;}.content {height: var(--h);position: absolute;left: var(--h);transform-origin: left top;transform: rotate(90deg);}}
}
</style>
效果：(现在不需要按住shift，可直接滑动滚轮实现页面横向滑动)
6.v-size-ob是自定义指令：（获取元素的宽高）
新建一个sizeOb.ts文件
const map = new WeakMap();
const ob = new ResizeObserver((entries) => {for (const entry of entries) {const handler = map.get(entry.target);if (handler) {const box = entry.borderBoxSize[0];handler({width: box.inlineSize,height: box.blockSize,});}}
});export default {mounted(el, binding) {ob.observe(el);map.set(el, binding.value);},unmounted(el) {ob.unobserve(el);},
};
在main.ts入口文件中引入
import { createApp } from "vue";
import "./style.css";
import App from "./App.vue";
import Antd from "ant-design-vue";
import "ant-design-vue/dist/reset.css";
import sizeOb from "./directives/sizeOb";let app = createApp(App);
app.config.globalProperties.msg = "hello";//自定义指令
app.directive("size-ob", sizeOb);app.use(Antd).mount("#app");
