Vue编写的登录界面

Question

使用rules的表单验证检测是否为空，username和code都可以检测空，但是password不可以，都是一样写的，不知道为啥不行。

<template>
  <div>
    <el-form :rules="rules" ref="loginForm" :model="loginForm" class="loginContainer">
      <h3 class="loginTitle">系统登录</h3>
      <el-form-item prop="username">
        <el-input type="text" v-model="loginForm.username" autocomplete="false" placeholder="Please enter username" class="loginUser"></el-input>
      </el-form-item>
      <el-from-item prop="pwd">
        <el-input type="password" v-model="loginForm.pwd" autocomplete="false" placeholder="Please enter password" class="loginPassword"></el-input>
      </el-from-item>
      <el-form-item prop="code">
        <el-input type="text" v-model="loginForm.code" autocomplete="false" placeholder="Please enter identifying code" class="loginIdentify"></el-input>
        <img src="capthcaurl">
      </el-form-item>
      <el-form-item>
        <el-checkbox v-model="checked" class="loginRemeber">Remeber me</el-checkbox>
        <el-button type="primary" style="width:100%" @click="submitLogin">Login</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>

<script>
export default {
  name: 'Login',
  data: function () {
    return {
      captchaurl: '',
      loginForm: {
        username: 'admin',
        pwd: '123456',
        code: ''
      },
      checked: true,
      rules: {
        username: [{required: true, message: '请输入用户名', trigger: 'blur'}],
        pwd: [{required: true, message: '请输入密码', trigger: 'blur'}],
        code: [{required: true, message: '请输入验证码', trigger: 'blur'}]
      }
    }
  },
  methods: {
    submitLogin: function () {
      this.$refs.loginForm.validate((valid) => {
        if (valid) {
          alert('submit!')
        } else {
          console.log('error submit!!')
          return false
        }
      })
    }
  }
}
</script>

.loginContainer{
  border-radius: 15px;

写代码从不看报错吗？看一下控制台错误：

看你的代码：单词form写成了from,控制台也有报错
<el-form-item> 写成： <el-from-item>
