折叠面板

简单封装折叠面板无需安装各个UI组件库，实现需要折叠面板样式

<template>
    <div v-if="collapseFlag">
        <div v-for="(item,index) in panelList" :key="index">
            <div
                :style="{width:width,height:height,background:color,borderTop:'1px solid #aaa',borderBottom:'1px solid #aaa'}">
                <div
                    :style="{textAlign: 'left',height:height,lineHeight:height,paddingLeft:'10px',position:'relative'}">
                    {{ item.title }}
                    <i v-if="showIcon"
                       :class="{'icon-triangle-left':(item.iconName == 'icon-triangle-left'),'icon-triangle-down':(item.iconName=='icon-triangle-down')}"
                       @click="change(index)"></i>
                    <span v-if="!showIcon"

index.js

const resultComps = {}
let requireComponent = require.context(

    false, // 不遍历子文件夹
    /\.vue$/ // 正则匹配 以 .vue结尾的文件

requireComponent.keys().forEach(fileName => {
    let comp = requireComponent(fileName)
    resultComps[fileName.replace(/^\.\/(.*)\.\w+$/, '$1')] = comp.default
})

export default resultComps

折叠面板样式

根据showIcon显示图标

   

 

 使用组件
