vue 滑块验证

1、在登录页同级目录下，新建滑块验证页面 JcRange.vue：

 2、JcRange.vue：

<template>
	<div ref="dragVerify" class="drag_verify" :style="dragVerifyStyle" @mousemove="dragMoving" @mouseup="dragFinish" @mouseleave="dragFinish" @touchmove="dragMoving" @touchend="dragFinish">
	<div class="dv_progress_bar" :class="{goFirst2:isOk}" ref="progressBar" :style="progressBarStyle"></div>
	<div class="dv_text" :style="textStyle" ref="message">
		<slot name="textBefore" v-if="$slots.textBefore" ></slot>
			{{message}}
			<slot name="textAfter" v-if="$slots.textAfter"></slot>
		</div>
		<div class="dv_handler dv_handler_bg" :class="{goFirst:isOk}" @mousedown="dragStart" @touchstart="dragStart" ref="handler" :style="handlerStyle">
			<i :class="handlerIcon"></i>
		</div>
	</div>
</template>
<script>

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,
            }
        },
        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");
      },
