单列选择器测试没有问题，但是多列选择器会能打开选择的list，但不知报错原因
代码：
<template>
<view class="content">
<picker mode="multiSelector" :range="range" @change="gdbm" @columnchange="onegdbm">
<view>多列</view>
</picker>
<view class="ff">
<picker mode="selector" :range="range1" @change="change1">
<view>单列</view>
</picker>
</view>
</view>
</template>
import citys from './city.js'
import provinces from './province.js'
import {uniList,uniListItem} from '@dcloudio/uni-ui'
export default {
components:{
uniList,
uniListItem,
},
data() {
return {
province_citys:[],//某个省下的所有城市
range:[provinces,['北京']],
range1:['a','b','c'],
}
},
