自从用饿了么框架重构项目以来，遇到 很多问题，我都有一一记录下来，现在特喜欢这个框架，说实话，如果你是用了vue这个技术栈的话，一定要用饿了么的pc端框架哦，遇到问题的时候在网上百度一下，就能找到解决方案，还有很多社区可以讨论，社区文档都比较成熟，很容易上手~~

在添加的时候，需要点击添加按钮，出现一个form弹框的效果
然后在表单里面填写内容，填写完成时，将内容提交。

示例代码：

<template>
  <div class="tab-container">
    <el-button
      class="filter-item"
      style="margin-left: 10px;"
      type="primary"
      icon="el-icon-edit"
      @click="handleCreate"
    >添加</el-button>
    <el-dialog :visible.sync="dialogFormVisible">
      <el-form
        :model="questionForm"
        ref="dataForm"
        label-position="left"
        label-width="90px"
        style="width: 400px; margin-left:50px;"
      >
        <el-form-item label="题目" prop="questionContent">
          <el-input type="textarea" :rows="2" v-model="questionForm.questionContent"></el-input>
        </el-form-item>
        <el-form-item label="分类">
          <el-radio-group v-model="questionForm.questionCategory" style="margin-right:12px;">
            <el-radio v-for="(radio, index) in subjectList" :key="index" :label="radio">{{radio}}</el-radio>
          </el-radio-group>
        </el-form-item>
        <el-form-item label="正确答案" prop="correctAnswer">

        </el-form-item>
        <el-form-item label="其他答案3" prop="otherAnswer3">
