Vue实现滑动验证功能

2022-04-17 02:04:54 来源：易采站长站作者：

用vue实现滑动验证码，鼠标点击滑动验证，验证成功之后会显示验证通过。

程序分析

1、鼠标的点击
2、滑块的拖动
3、未验证之前滑动条上显示的文字
4、滑块箭头指向Vue函数
5、判断是否拖动完毕
6、拖动完毕时改变背景色并显示验证成功

有没有感觉很奇妙的呢？？？

在欣赏代码之前准备工作要做好的！！！
**特别注意：**相关架包的引入（三个架包）

<script src="js/vue.js"></script><script src="https://unpkg.com/element-ui/lib/index.js"></script><script src="js/jquery.js"></script>
