SPA项目开发之CRUD+表单验证

dialog布局

表单验证

Form组件提供了表单验证的功能，只需要通过 rules 属性传入约定的验证规则，
并将Form-Item的prop属性设置为需校验的字段名即可

<el-form-item label="活动名称" prop="name">
<el-form :model="ruleForm" :rules="rules" ref="ruleForm"

注：有多个表单，怎么在提交进行区分？
我们在rules这里写了对表单的验证规则，但是我们如何在methods里进行指定的表单进行认证所以我们一开始就在el-form里写了ref="ruleForm"，我们在methods里就可以用

清空表单验证信息

  this.$refs[formName].resetFields();

CUD

1. 新增
2. 删除/修改
3. 在上使用特殊的slot-scope 特性，可以接收传递给插槽的prop
