表单默认空白，无数据时赋默认值，新增时赋默认值

一.首先定义一个赋默认值的方法，然后初始化时调用，新增时调用

二.新增与更新，入参一致，所以可以共用一个接口，一个方法，根据是否有id判断

三.生成表单尽量用map不用push，因为push可能会出现重复添加的情况，但map每次会生成新的数组不用考虑这种情况

  <el-button type="primary" @click="switcSave()">保存</el-button>

    <el-button type="primary" @click="switcSave('add')">新增</el-button>
    <el-button type="danger" :disabled="this.flag" plain @click="doDelete">删除</el-button>
