async-validator使用事项

注意属性的绑定

el-from标签中绑定model属性和rules属性。

1. model:保存值得对象

2. 规则对象

<el-form
      label-width="60px"
      class="form_count"
      :model="acount"
      :rules="rules"
      ref="formRef"
    >
      <el-form-item label="账号" prop="name">
        <el-input type="text" v-model="acount.name"></el-input>
      </el-form-item>
      <el-form-item label="密码" prop="password">
        <el-input type="password" v-model="acount.password"></el-input>
      </el-form-item>
    </el-form>
    
    //属性对象
    const acount = reactive({
      name: "",
      password: ""
    });
    
  //为每个属性编写规则
 const rules = {
  name: [
    {
      required: true,
      message: "账号是必传的哦~",
      trigger: "blur"
    },
    {
      pattern: /^[a-z0-9]{5,10}$/,
      message: "用户名必须是5~10个字母或者数字~",
      trigger: "blur"
    }
  ],
  password: [
    {
      required: true,
      message: "密码是必传的哦~",
      trigger: "blur"
    },
    {
      pattern: /^[a-z0-9]{5,}$/,
      message: "密码长度不能少于5位哦~",
      trigger: "blur"
    }
  ]
};
