vue3滑块验证码代码实现

实现滑块验证码可以使用 Vue3 的组件库 Element Plus 中的 Slider 组件。具体实现步骤如下：

1. 安装 Element Plus：`npm install element-plus --save`

2. 在 main.js 中引入 Element Plus：`import ElementPlus from 'element-plus'`，并注册组件：`app.use(ElementPlus)`

3. 在组件中使用 Slider 组件，设置 v-model 绑定滑块的值，设置 :min 和 :max 分别为滑块的最小值和最大值，设置 :show-input 控制是否显示输入框，设置 :height 控制滑块的高度。

示例代码如下：

<template>
  <div>
    <el-slider v-model="sliderValue" :min="0" :max="100" :show-input="true" :height="30"></el-slider>
  </div>
</template>

<script>
export default {
  data() {
    return {
      sliderValue: 0
    }
  }
}
</script>

vue3 写滑块验证码

以下是一个简单的滑块验证码的 Vue3 实现：

<template>
  <div class="slider-captcha">
    <div class="captcha-container">
      <div class="captcha-image" ref="captchaImage">
        <img :src="captchaUrl" alt="captcha" @load="handleCaptchaLoad" />
      </div>
      <div class="slider" ref="slider" @mousedown="handleMouseDown" @mousemove="handleMouseMove" @mouseup="handleMouseUp">
        <div class="slider-icon" ref="sliderIcon"></div>
      </div>
    </div>
    <div class="result" v-if="isVerified">验证通过</div>
  </div>
</template>

<script>
import { ref } from 'vue';

export default {
  name: 'SliderCaptcha',
  setup() {
    const captchaUrl = ref('https://picsum.photos/300/150');
    const isVerified = ref(false);
    let isDragging = false;
    let startX = 0;
    let sliderWidth = 0;
    let sliderMaxX = 0;
    let dragOffset = 0;

    const handleCaptchaLoad = () => {
      sliderWidth = Math.floor(getComputedStyle($refs.slider).width.slice(0, -2));
      sliderMaxX = sliderWidth - 40;
    };

    const handleMouseDown = (event) => {
      isDragging = true;
      startX = event.clientX;
      dragOffset = $refs.slider.offsetLeft;
    };

    const handleMouseMove = (event) => {
      if (!isDragging) return;
      const x = event.clientX - startX + dragOffset;
      $refs.slider.style.left = `${Math.max(0, Math.min(sliderMaxX, x))}px`;
    };

    const handleMouseUp = () => {
      isDragging = false;
      if (Math.abs($refs.slider.offsetLeft - sliderMaxX) < 5) {
        isVerified.value = true;
      } else {
        $refs.slider.style.left = '0';
      }
    };

    return {
      captchaUrl,
      isVerified,
      handleCaptchaLoad,
      handleMouseDown,
      handleMouseMove,
      handleMouseUp,
    };
  },
};
</script>

<style scoped>
.slider-captcha {
  position: relative;
  width: 300px;
  height: 150px;
}
.captcha-container {
  position: relative;
  width: 100%;
  height: 100%;
  overflow: hidden;
}
.captcha-image {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
.slider {
  position: absolute;
  top: 50%;
  left: 0;
  width: 40px;
  height: 40px;
  transform: translateY(-50%);
  background-color: #ccc;
  border-radius: 50%;
  cursor: pointer;
}
.slider-icon {
  position: absolute;
  top: 0;
  left: 0;
  width: 40px;
  height: 40px;
  border-radius: 50%;
  background-color: #fff;
  box-shadow: 1px 1px 3px rgba(0, 0, 0, 0.3);
}
.result {
  position: absolute;
  top: 50%;
  left: 0;
  width: 100%;
  text-align: center;
  font-size: 18px;
  color: #fff;
  transform: translateY(-50%);
  background-color: green;
  padding: 10px;
}
</style>

这个组件会显示一个随机的图片作为验证码，下面有一个滑块。用户需要拖动滑块，使其到达滑动条的末端，才可通过验证。如果验证通过，会显示一个“验证通过”的提示。
