                            rules={[

                                {

                                    required: true,

                                    message: 'Please input your Username!',

                                },

                                {

                                },

                            ]}

                        >

                            <Input prefix={<UserOutlined className="site-form-item-icon" />} placeholder="Username" />

                                    validator: (_, value) =>{

                                    if(value.length >= 6 && value.length<=10) {

                                        return Promise.resolve()

                                    }else{

                                        return Promise.reject('密码长度必须是6~10位')

                                    }

                                  }

                                }

                            ]}

                        >

                            <Input

                                prefix={<LockOutlined className="site-form-item-icon" />}

                                type="password"

                                placeholder="Password"

                            />

                        </Form.Item>

antd-design-vue form表单验证,禁止输入中文,只数字,等验证要怎么写呀~~

因为是在表单里写的,所以有点迷,不知道要怎么写..
请大神给个思路~~~
<a-form-item v-bind="formStyle" label="别名(英文)">
    <a-input
        placeholder="请输入别名"
        v-decorator="['menuPath', { rules: [
            { required: true, message: '请输入别名' },
            { validator: (rule, value, cb) => this.changeKey(rule, value, cb) }
        ] }]"
    />
</a-form-item>
把采纳给了楼下
我现在的解决办法如下: 感觉这样更方便点儿
 <a-form-item v-bind="formStyle" label="别名(英文)">
    <a-input
        placeholder="请输入别名"
        maxlength="50"
        minlength="3"
        v-decorator="['menuPath', { rules: [
            { required: true, message: '请输入别名' }
        ],
            getValueFromEvent: (event) => {
                return event.target.value.replace(/[\u4E00-\u9FA5]/g,'')
            }
         }]"
    />
</a-form-item>

相关代码

// 只列举一个表单项,其他的规则都是必填。

<a-form :form="form" @submit="handleSubmit" layout="vertical">
  <a-form-item
    label="标题"
    :labelCol="formItemLayout.labelCol"
    :wrapperCol="formItemLayout.wrapperCol">
      <a-input
        v-decorator="[
          'title',
          {initialValue: formData.title, rules: [{ required: true, message: '请输入标题' }]}
        ]"
        placeholder="标题" />
  </a-form-item>
</a-form>

// 提交

async handleSubmit (e) {
  event.preventDefault()
  this.form.validateFields((err, values) => {
    if (!err) {
      Object.assign(this.formData, values)
      Object.assign(this.formData, { updatedAt: Date.now() })
      console.log('提交信息成功', this.formData)
    }
  })
  if (this.formData.id) {
    const res = await updateBanner(this.formData)
    console.log('编辑', res)
  } else {
    const res = await createBanner(this.formData)
    console.log('新增', res)
  }
},


以下是一段手机号的的自定义校验,在提交表单的时候form.validateFields总是出现错误,方法无法向下执行Vue+Antd表单校验form.validateFields执行错误的解决方法

在自定义校验里面每一个判断都要调用callback(),要保证方法最后执行到的永远都是callback()

//自定义校验(检查手机号是否输入正确)
checkPhone(rule, value, callback) {
  if (value != null && value != "") {
    var reg = /^1[3456789]\d{9}$/;
    if (!reg.test(value)) callback(new Error("手机号格式不正确"));
    //调用callback
    else callback();
  } else {
    callback();
  }
}
