vue-cli

element ui

表单验证

实现效果：

注意一点：

出现一个警告：[Element Warn][Form]model is required for validat

解决方法：将form绑定数据由v-model换成 :model

具体代码：

<template>
  <div id="login">
    <div class="loginToHome">
      <el-form
        ref="form"
        :model="form"
        :rules="ruleForm"
        status-icon
        label-width="80px"
        class="loginForm"
      >
        <h3>登陆</h3>
        <el-form-item
          label="用户名"
          prop="name"
        >
          <el-input
            type="text"
            v-model="form.name"
            auto-complete="off"
            placeholder="请输入用户名"
          ></el-input>
        </el-form-item>
        <el-form-item
          label="密码"
          prop="password"
        >

            auto-complete="off"
