使用 v-model 而不是 :model 在 el-form 中，应该使用 :model 而不是 v-model。Vue 3 中的 v-model 用于双向绑定，而 :model 用于将数据传递给表单。

怎么创建一个注册表单，带验证功能

• 输入框记着添加v-model绑定数据
• 在它上边的form-item加上prop，做校验

<script setup>javascript">
import { User, Lock } from '@element-plus/icons-vue'
import { ref } from 'vue'
const registerData=ref({username:'',password:'',rePassword:''
})
const rePasswordValid=(rule,value,callback)=>{if(value==='')callback(new Error('请确认密码'))if(value!==registerData.value.password)callback(new Error('两次密码不一致')) 
}
const registerDataRules=ref({username:[{required:true,message:'请输入用户名',trigger:'blur'},{min:6,max:15,message:'用户名长度在6-15位之间',trigger:'blur'}],password:[{required:true,message:'请输入密码',trigger:'blur'},{min:6,max:15,message:'密码长度在6-15位之间',trigger:'blur'}],rePassword:[{validator:rePasswordValid,trigger:'blur'}]
})
const register=()=>{console.log(registerData)
}
