vue2 vant-ui 实现搜索过滤、高亮功能
vant 实现是通过输入框(van-field)事件触发弹出层(van-popup),弹出层(van-popup)中包括了选择器(van-picker)

前言
回顾之前,使用cube-ui实现公司售后部门方便查看公司产品状态及配置设备的一个移动端项目,其中有个小功能 cube-ui 实现搜索过滤、高亮功能。cube-ui 实现搜索过滤、高亮功能地址,如何呢,售后开始搞事了,说这个功能不好用什么的,不能粘贴啥的(因为我设置了点击就弹让他选的),说要换个 UI ,说这 UI 不好用。
一、需求
流程
需求还是一样,只是 ui 变了,逻辑也会变点
实现效果
原效果:
现效果:
差别: 其实效果没多大变化,只是更换了 UI 和选择框标题修改为输入框
功能实现
概述: vant 实现是通过输入框(van-field) 事件触发 弹出层(van-popup),弹出层(van-popup)中包括了 选择器(van-picker)
