【element-ui】运用vueX+elementUI 制作问答题，数据增加了之后，页面切换/记载迟缓(延迟0.7s左右)，有什么好的解决办法？
- 我感觉数据加载和获取多了就导致了页面卡顿
2、 这是部分数据和运行的逻辑。希望能提供一点建议，3Q3Q！！！！！！！！！！！！！！
回答：
我的逻辑是这样的，就是自己保存进了state,再从不同界面取出state的数据
<template> <div class="single" ref="single">
<div class="beforeContent">
<h2 v-show="this.biaoti.length>0" v-html="this.biaoti[0]"></h2>
<p class="ppp" v-html="this.biaotiNeirong[0]"></p>
<el-button type="primary" @click="back">编辑</el-button>
</div>
<div class="titleWrapper">
<div class="top">
<p>1、"index"</p>
<p>必填</p>
<!--单选标题部分-->
<el-form :model="ruleForm3" :rules="rules3" ref="ruleForm3" class="demo-ruleForm">
<el-form-item label="编辑选项标题信息" prop="singleTit">
<el-input v-model="ruleForm3.singleTit" placeholder="请输入选项标题信息"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="submitForm3('ruleForm3')">完成</el-button>
<el-button @click="resetForm3('ruleForm3')">重置</el-button>
</el-form-item>
</el-form>
<p style="margin:10px 0 5px;">添加图片 <small style="font-size:13px;color:gray;">[选填]</small></p>
<!--添加图片上传功能-->
<div style="border: 1px dashed red;" class="imgAdd">
