vue 表单 验证 async-validator

1、使用插件async-validator

async-validator 地址：https://github.com/yiminghe/async-validator

2、示例（vue+element-ui）

<el-form :model="numberValidateForm" ref="numberValidateForm" label-width="100px" class="demo-ruleForm">
  <el-form-item label="年龄" prop="age" :rules="[ { required: true, message: '年龄不能为空'}, { type: 'number', message: '年龄必须为数字值'} ]"
  >
    <el-input type="age" v-model.number="numberValidateForm.age" autocomplete="off"></el-input>
  </el-form-item>
  <el-form-item>
    <el-button type="primary" @click="submitForm('numberValidateForm')">提交</el-button>
    <el-button @click="resetForm('numberValidateForm')">重置</el-button>
  </el-form-item>
</el-form>
<script> export default { data() { return { numberValidateForm: { age: '' } }; }, methods: { submitForm(formName) { this.$refs[formName].validate((valid) => { if (valid) { alert('submit!'); } else { console.log('error submit!!'); return false; } }); }, resetForm(formName) { this.$refs[formName].resetFields(); } } } </script>

注意校验书写格式：

{ required: true, message: '年龄不能为空'},
{ type: 'number', message: '年龄必须为数字值'}
像校验邮箱、数值类型类型时，多行配置校验规则。
