使用Vue.js开发后台管理平台登录页面

使用Vue.js搭建后台管理系统

登录页面

views/login/index.vue

页面基础标签

<template>
  <h3>管理员登录</h3>
</template>
<script>
export default {
  // 定义页面组件名称
  name: "login",
};
</script>
<style scoped>
</style>

配置路由

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'login',
      component: () => import('@/views/login/index')
    }
  ]
})

添加简单表单

<template>
  <el-form
    ref="loginForm"
    :model="loginForm"
    class="login-form"
    auto-complete="on"
    label-position="left"
  >
    <h3 class="title">管理员登录</h3>
    <el-form-item prop="username">
      <span class="svg-container">
        <svg-icon icon-class="user" />
      </span>
      <el-input
        v-model="loginForm.username"
        name="username"
        type="text"
        tabindex="1"
        auto-complete="on"
        placeholder="管理员账户"
      />
    </el-form-item>
    <el-form-item>
      <span class="svg-container">
        <svg-icon icon-class="password" />
      </span>
      <el-input
        v-model="loginForm.password"
        name="password"
        type="text"
        tabindex="1"
        auto-complete="on"
        placeholder="管理员密码"
      />
    </el-form-item>
    <el-button type="primary" style="width: 100%; margin-bottom: 30px"
      >登录</el-button
    >
  </el-form>
</template>
<script>
export default {
  // 定义页面组件名称
  name: "login",
  data() {
    return {
      loginForm: {
        username: "admin123",
        password: "admin123",
        code: "",
      },
    };
  },
};
</script>
<style scoped>
</style>

添加点击事件和表单校验

 loginRules: {
        username: [{ required: true, message: '管理员账户不允许为空', trigger: 'blur' }],
        password: [
          { required: true, message: '管理员密码不允许为空', trigger: 'blur' },
          { validator: validatePassword, trigger: 'blur' }
        ]
      },

<el-button :loading="loading" type="primary" style="width:100%;margin-bottom:30px;" @click.native.prevent="handleLogin">登录</el-button>

    handleLogin() {
      this.$refs.loginForm.validate(valid => {
        if (valid && !this.loading) {
          this.loading = true
          this.$store.dispatch('LoginByUsername', this.loginForm).then(() => {
            this.loading = false
            this.$router.push({ path: this.redirect || '/' })
          }).catch(response => {
            if (response.data.data) {
              this.codeImg = response.data.data
            }
            this.$notify.error({
              title: '失败',
              message: response.data.errmsg
            })
            this.loading = false
          })
        } else {
          return false
        }
      })
    }

修改样式，背景颜色。

<template>
  <div class="login-container">
    <el-form ref="loginForm" :model="loginForm" :rules="loginRules" class="login-form" auto-complete="on" label-position="left">
      <div class="title-container">

        </span>
        <el-input v-model="loginForm.username" name="username" type="text" tabindex="1" auto-complete="on" placeholder="管理员账户" />
      </el-form-item>

      <el-form-item prop="password">
        <span class="svg-container">
          <svg-icon icon-class="password" />

        <el-input v-model="loginForm.password" :type="passwordType" name="password" auto-complete="on" tabindex="2" show-password placeholder="管理员密码" @keyup.enter.native="handleLogin" />
      </el-form-item>

      <!-- <el-form-item prop="code">

      <el-button :loading="loading" type="primary" style="width:100%;margin-bottom:30px;" @click.native.prevent="handleLogin">登录</el-button>

      <div style="position:relative">
