详解vue如何使用rules对表单字段进行校验

 <Form ref="loginForm" :model="form" :rules="rules" @keydown.enter.native="handleSubmit" class="form-con">            <FormItem prop="phone">              <Input v-model="form.phone" prefix="md-person" placeholder="请输入您的手机号" size="large" class="login-form-input" :maxlength="11"></Input>            </FormItem>            <FormItem prop="password">              <Input type="password" v-model="form.password" prefix="md-lock" placeholder="请输入您的密码" size="large" class="login-form-input" :maxlength="100"></Input>            </FormItem>            <FormItem prop="code">              <Input v-model="form.code" placeholder="请输入验证码" prefix="ios-barcode" size="large" class="login-form-input" :maxlength="4"></Input>              <img @click="refLoginImg" :src="loginImgSrc" class="login-img"/>            </FormItem>            <FormItem>              <Button @click="handleSubmit" :loading="submitLoading" type="info" long size="large" class="login-btn" icon="md-log-in">                <span v-if="!submitLoading">立即登录</span>                <span v-else>正在登录，请稍候...</span>              </Button>            </FormItem>          </Form>
