本文实例为大家分享了基于Vue可左右滑动按钮组组件，供大家参考，具体内容如下
左右两箭头控制按钮组左右移动，双击到最左或最右边，功能比较简单。如下所示
<template>
<div class="demoButtons">
<div class="buttonF">
<el-row style="height:30px ">
<el-col class="lableI"><i class="el-icon-arrow-left " @click="moveButtons('left')" @dblclick="moveSide('left')" /></el-col>
<el-col ref="buttonBody" class="buttonBody">
<el-row id="buttonRow" ref="buttonRow">
<el-tag :style="{'width':buttonWidth+'px'}" v-for="(item, index) in buttonData" :key="index" :type="index == clickIndex ? '' : 'info'" @click="resetData(index, item)">
<el-tooltip v-if="item.name && item.name.length > parseInt(buttonWidth/12) - 1" placement="top" :content="item.name" effect="light">
<span>{{ resetName(item.name) }}</span>
</el-tooltip>
<span v-else>{{ item.name }}</span>
</el-tag>
</el-row>
</el-col>
<el-col class="lableI"><i class="el-icon-arrow-right " @click="moveButtons('right')" @dblclick="moveSide('right')" /></el-col>
</el-row>
</div>
</div>
</template>
