uni-vue 组件选中和动态数据图标的使用

作者:互联网

index.vue内使用list组件,组件的功能主要包含1:根据不同数据显示不同图标,2:选中事件

实现1:利用:class="iconClass" 

实现2:vue基础 子传父$emit,父传子prop

代码:父组件index.vue

<template>
    <view class="content">
        <nav-bar></nav-bar>
        <view class="dg">
            <view class="content">
                <!-- 搜索框 -->
