backend 2025/7/2 7:15:51

组件滚动通知只能实现简单的滚动效果，不能实现滚动内容中的字进行不同颜色的更改，下面实现一个无缝衔接的滚动动画，可以根据自己的需要进行艺术化的更改需要滚动的内容，也可以自定义更改滚动速度。

<template><view class="container"><!-- 文字滚动条 --><view v-for="(item, index) in scrollItems" :key="'text-' + index"class="scroll" :style="{'--t': item.duration + 's'}"><view class="scroll-row"><text v-for="(skill, i) in skills" :key="i"class="skill-tag"@click="handleSkillClick(skill)">{{ skill }}</text></view><view class="scroll-row"><text v-for="(skill, i) in skills" :key="i + 'copy'"class="skill-tag"@click="handleSkillClick(skill)">{{ skill }}</text></view></view><!-- 彩色方块滚动条 --><view class="scroll img-box" style="--t: 25s"><view class="scroll-row"><view v-for="n in 9" :key="n"class="color-box" :style="{'--r': (n-1)*40}"@click="changeBoxColor(n)">{{ n }}</view></view><view class="scroll-row"><view v-for="n in 9" :key="n + 'copy'"class="color-box" :style="{'--r': (n-1)*40}"@click="changeBoxColor(n)">{{ n }}-1</view></view></view></view>
</template>

<script setup>
import { ref } from 'vue'const skills = ref(['HTML', 'CSS', 'JavaScript', 'Vue', 'React', 'Figma', 'Photoshop'
])const scrollItems = ref([{ duration: 20 },{ duration: 30 },{ duration: 10 },{ duration: 35 }
])const handleSkillClick = (skill) => {uni.showToast({title: `点击了: ${skill}`,icon: 'none'})
}const changeBoxColor = (n) => {// 在实际应用中，你可能需要找到对应的DOM元素来修改样式// 这里只是演示点击事件uni.showToast({title: `点击了方块 ${n}`,icon: 'none'})
}
</script>
