背景
今天在开发限时练-提分加项目的时候，有一个需要锚点定位的需求，而在Vue项目中，使用传统的在a标签的href属性中写id的方法无效，会导致浏览器的地址改变从而跳转到其他页面。
解决
最终参考vue2.0中怎么做锚点定位改问题下的回答实现了效果。
<template>
<div class="score-preview-container">
<div class="content-box">
<div class="content-page-box">
<GlobalAnalysis :id="#anchor-0" />
<ErrorMerge :id="#anchor-1" />
<DoExercise :id="#anchor-2" />
</div>
<div class="nav-button-box">
<span class="nav-button-fix">
<div class="nav-button" v-for="(item,index) in buttonArr" :key="index" :class="{active : activeBtn == index}" @click="goAnchor('#anchor-'+index,index)">{{item}}</div>
</span>
</div>
</div>
</div>
</template>
<script>
import { mapActions } from "vuex";
import GlobalAnalysis from "./components/GlobalAnalysis.vue";
import ErrorMerge from "./components/ErrorMerge.vue";
import DoExercise from "./components/DoExercise.vue";
export default {
name: "score-preview",
components: { GlobalAnalysis, ErrorMerge, DoExercise },
data() {
return {
buttonArr: ["整体分析", "错题整理", "提分训练"],
activeBtn: 0
};
},
mounted() {
this.dataInit();
},
methods: {
...mapActions("v2-score-preview", [
"fetchClassScoreData",
"fetchPersonalReportData",
"fetchErrorQuestionData",
"fetchExerciseData"
]),
//初始化
dataInit() {
this.fetchClassScoreData();
this.fetchPersonalReportData();
this.fetchErrorQuestionData();
this.fetchExerciseData();
},
//锚点跳转
goAnchor(selector, index) {
this.activeBtn = index;
document.querySelector("#app-root").scrollTop = this.$el.querySelector(selector).offsetTop;
}
}
};
</script>
另外，参考页面内锚点定位及跳转方法总结文章中的第四种方法，发现使用scrollIntoView()方法也能实现锚点定位的效果。
//锚点跳转
goAnchor(selector, index) {
this.activeBtn = index;
this.$el.querySelector(selector).scrollIntoView()
}
