简单粗暴直接上代码:
<a-form-itemlabel="用户名":label-col="{ span: 5, offset: 1 }":wrapper-col="{ span: 15 }"><a-inputplaceholder="请输入"v-decorator="['userName',{ rules: [{ validator: validateUserName},{ required: true, message: '请输入用户名'}],// 注意validateTrigger要写在rules外面// 验证的触发是validateTrigger，不是triggervalidateTrigger: 'blur' },]"/></a-form-item>
