elementui-plus实现锚点功能

效果：点击导航栏菜单，定位到指定的地方

适用于单界面操作

<template>  
  <el-menu>  
    <el-menu-item index="1" @click="scrollToAnchor('section1')">Section 1</el-menu-item>  
    <el-menu-item index="2" @click="scrollToAnchor('section2')">Section 2</el-menu-item>  
  </el-menu>  
  
  <div style="height: 1000px;"> <!-- 假设页面有足够的高度以展示滚动效果 -->  
    <h2 id="section1">Section 1</h2>  
    <!-- 更多内容 -->  
    <h2 id="section2">Section 2</h2>  
    <!-- 更多内容 -->  
  </div>  
</template>  
  
<script>  
export default {  
  methods: {  
    scrollToAnchor(anchorId) {  
      const element = document.getElementById(anchorId);  
      if (element) {  
        element.scrollIntoView({ behavior: 'smooth' });  
      }  
    }  
  }  
}  
</script>
