vue2和elementUI 打造落日余晖登录页和滑块校验

以下是一个使用Vue 2和Element UI创建的登录页面，其中包括一个滑块验证组件的简单示例：

<template>
  <el-form ref="loginForm" :model="loginForm" :rules="rules" class="login-container">
    <h3 class="login-title">落日余晖登录</h3>
    <el-form-item prop="username">
      <el-input v-model="loginForm.username" placeholder="用户名"></el-input>
    </el-form-item>
    <el-form-item prop="password">
      <el-input type="password" v-model="loginForm.password" placeholder="密码"></el-input>
    </el-form-item>
    <el-form-item prop="captcha">
      <el-input v-model="loginForm.captcha" placeholder="验证码">
        <template slot="append">
          <img :src="captchaSrc" @click="refreshCaptcha" class="captcha-img"/>
        </template>
      </el-input>
    </el-form-item>
    <el-form-item prop="sliderCaptcha">
      <slider-captcha :captcha-src="sliderCaptchaSrc" @success="onSliderVerifySuccess"></slider-captcha>
    </el-form-item>
    <el-form-item>
      <el-button :loading="loading" type="primary" style="width:100%;" @click="handleLogin">登录</el-button>
    </el-form-item>
  </el-form>
</template>
 
<script>
import SliderCaptcha from './SliderCaptcha.vue'; // 假设你有一个滑块组件
 
export default {
  components: {
    SliderCaptcha
  },
  data() {
    return {
      loginForm: {
        username: '',
        password: '',
        captcha: '',
        sliderCaptcha: ''
      },
      rules: {
        // 验证规则
      },
      captchaSrc: '', // 验证码图片地址
      sliderCaptchaSrc: '', // 滑块验证码图片地址
      loading: false
    };
  },
  methods: {
    handleLogin() {
      this.$refs.loginForm.validate(valid => {
        if (valid) {
          this.loading = true;
          // 登录逻辑...
        }
      });
    },
    refreshCaptcha() {
      // 刷新验证码逻辑...
      this.captchaSrc = `captcha?timestamp=${new Date().getTime()}`;
    },
    onSliderVerifySuccess(token) {
      this.loginForm.sliderCaptcha = token;
    }
  },
  created() {
    this.refreshCaptcha();
  }
};
</script>
 
<style scoped>
.login-container {
  width: 350px;
  margin: 180px auto 0;
  padding: 35px;
  background-color: #fff;
  border: 1px solid #eaeaea;
