用Vue-element写一个简单的注册页面

**首先要安装element **

npm i element-ui -S 安装elementui 依赖

然后就可以使用ele里面的组件

最后的效果图如下：

  <div class="myform">
    <h1>注册页</h1>
    <el-form
      :model="ruleForm"
      status-icon
      :rules="rules"
      ref="ruleForm"
      label-width="100px"
    >
      <el-form-item label="用户名" prop="username">
        <el-input v-model="ruleForm.username"></el-input>
      </el-form-item>
      <el-form-item label="邮箱" prop="email">
        <el-input v-model="ruleForm.email"></el-input>
      </el-form-item>
      <el-form-item label="密码" prop="password">
        <el-input
          type="password"
          v-model="ruleForm.password"
          autocomplete="off"
        ></el-input>
      </el-form-item>
      <el-form-item label="确认密码" prop="repassword">
        <el-input
          type="password"
          v-model="ruleForm.repassword"
          autocomplete="off"
        ></el-input>
      </el-form-item>
      <el-form-item class="btn-sty">
        <el-button type="primary" @click="submitForm('ruleForm')"
          >注册</el-button
        >
        <el-button @click="resetForm('ruleForm')">重置</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>
