怎么样做网站代建站之星模板的使用

页面需求：

• 点击左侧版本号，右侧展示对应版本内容并置于顶部
• 右侧某一内容滚动到顶部时，左侧需要展示高亮

实现效果：

实现代码：

<template><div><div class="historyBox pd-20 bg-white"><div class="w100 flex h100" v-if="versionList.length > 0"><div class="left size-14"><divv-for="(item, index) in versionList":key="index"class="leftItem pd-10 pointer":class="index == activeIndex ? 'isActive' : ''"@click="gotoTarget(index)"><div>{{ item.versionNumber }}</div><div>{{ item.releaseTime }}</div></div></div><div class="right"><divv-for="(item, index) in versionList":key="index"class="rightItem pd-20 center":class="index == activeIndex ? 'isActive' : ''"><div v-html="item.versionDescription" class="ql-editor w60"></div></div></div></div><div class="w100 h100 center size-16 gray-2" v-else>暂无版本记录</div></div></div>
</template><script>
