天气晴朗，天空万里无云，温暖的阳光洒在人的身上，就像是一位母亲轻轻地抚摸着我们，微风徐徐，波光粼粼，站在美丽的湖边尽情享受大自然的无穷魅力。
本文实例为大家分享了Vue滑块验证的实现，代码如下
<template>

<div class="drag_bg"></div>
<div class="drag_text">{{confirmWords}}</div>
<div ref="moveDiv"

:class="{'handler_ok_bg':confirmSuccess}"
class="handler handler_bg"
style="position: absolute;top: 0px;left: 0px;"></div>
</div>
</template>
