3、页面调用：(验证滑块成功的，一个可以调用成功方法，另一个可以判断 this.isPassing 的值，重置滑块的时候，直接调用 this.reset() 即可)

<template>
    <el-row style="margin-top:10px;">
         <drag-verify
             ref="dragVerify"
             :width="360"
            :height="40"
            progressBarBg="#FFA500"
            background="#F5F5F5"
            :isPassing.sync="isPassing"
             text="请按住滑块拖动"
             successText="验证通过"
             handlerIcon="el-icon-d-arrow-right"
             successIcon="el-icon-circle-check"
             @passcallback="passcallback2">
        </drag-verify>
    </el-row>
</template>

import JcRange from './JcRange.vue' //引入滑块验证页面

export default {
        name: 'Login',
        data() {
            return {
                status: false,
            }
        },
        components: {
　　　　　　  'drag-verify': JcRange,
　　　　 },
        methods: {
            passcallback2() {
                console.log("滑块验证成功的方法");
            },
        }
}

4、重置滑块：

reset() {
        console.log("重置滑块");
        this.isPassing = false;
        if(this.$refs.dragVerify != undefined){
          this.$refs.dragVerify.reset();
        }
      },
      passcallback2() {
        console.log("滑块验证成功走的方法");
      },
