element表单回车登录解决的方法

#eleMent-ui 回车登录解决方法
直接上代码
在form表单设置默认的提交按钮后需要阻止表单默认提交事件，在表单上添加 @submit.native.prevent
@keyup.enter.native 是回车调用的方法

<template>
  <div class="loginContain">
    <div class="nav">
      <router-link to = '' class="navItem active">登录</router-link>
      <router-link to = "signUp" class="navItem">注册</router-link>
    </div>
    <div class="content_bx">
      <el-form action="" :model="loginData" :rules="rules" ref="rulForm" label-width="0" @submit.native.prevent>
        <el-form-item  prop="phone">
          <el-input class="input" autocomplete="off" v-model.number="loginData.phone" maxlength="11" placeholder="手机号" ></el-input>
       </el-form-item>
        <el-form-item prop="password">
          <el-input class="input" autocomplete="off" type="password" v-model="loginData.password" maxlength="16" placeholder="密码"></el-input>
        </el-form-item>
        <el-form-item>
          <el-row>
            <el-button class="btn_signIn" type="primary" @click = "submitForm('rulForm')" @keyup.enter.native="loginEnter">登录</el-button>
          </el-row>
        </el-form-item>
        <div class="findPasswordRow">
          <router-link class="findPassword" to = 'resetPassword'>找回密码</router-link>
        </div>
      </el-form>
    </div>
  </div>
