实现思路
在vue中如何复制一份列表出来呢且不能丢失绑定的事件，很简单使用slot插槽，使用两个插槽我们就拥有了两个列表
<div class="listScroll" ref="box">
<slot></slot>
<slot></slot>
</div>组件完整代码
<template>
<div class="listScroll" ref="box">
<slot></slot>
<slot></slot>
</div>
</template>
<script>
export default {
name: "listScroll",
created() {},
mounted() {
//在盒子内容高度小于可视高度时不滚动
if (this.boxHeight < this.ele0.clientHeight) {
this.start(this.height);
this.setEvet();
} else {
this.isScroll = false;
}
},
props: {
speed: {
default: 1,
type: Number,
},
},
computed: {
//第一个slot
ele0() {
return this.$refs.box.children[0];
},
//第二个slot
ele1() {
return this.$refs.box.children[1];
},
//盒子的可视高度
boxHeight() {
return this.$refs.box.clientHeight;
},
},
data() {
return {
height: 0,
isScroll: true,
};
},
methods: {
//鼠标移入停止滚动 移出继续滚动
setEvet() {
this.$refs.box.onmouseenter = () => {
this.isScroll = false;
// this.height = 0;
};
this.$refs.box.onmouseleave = () => {
this.isScroll = true;
this.$nextTick(() => {
this.start(this.height);
});
};
},
//滚动方法
start(height) {
this.ele0.style = `transform:translateY(-${height}px);`;
this.ele1.style = `height:${this.boxHeight}px;transform:translateY(-${height}px);overflow: hidden;`;
if (height >= this.ele0.clientHeight) {
this.height = 0;
} else {
this.height += this.speed;
}
if (!this.isScroll) return;
window.requestAnimationFrame(() => {
this.start(this.height);
});
},
},
};
</script>
<style lang="less" scoped>
.listScroll {
overflow: hidden;
}
.hover {
overflow-y: auto;
}
.hide {
display: none;
}
</style>使用
<template>
<div class="scroll">
<list-scroll class="box" :speed="1">
<div class="list">
<div class="item" v-for="item in list" :key="item.xh">
<span>{{ item.xh }}</span
><span>{{ item.label }}</span>
</div>
</div>
</list-scroll>
</div>
</template>
<script>
import ListScroll from "@/components/listScroll";
export default {
name: "scroll",
components: { ListScroll },
data() {
return {
list: new Array(10)
.fill(1)
.map((s, i) => ({ xh: i + 1, label: "hello wrold" })),
};
},
};
</script>
<style lang="less" scoped>
.box {
height: 300px;
}
.list {
padding: 0 10px;
width: 300px;
.item {
display: flex;
justify-content: space-between;
padding: 5px 0;
cursor: pointer;
&:hover {
background-color: #95a5a6;
}
}
}
</style>至此一个简单的无缝滚动就完成了（vue2和vue3通用）
