小程序 时分秒

好记性不如烂笔头，何况记性还不好。

wxml

    <picker mode="multiSelector" value="{{dateTime}}" bindchange="changeDateTime" range="{{dateTimeArray}}">
        <view class='text-item flex inp-wrapper'>
            <text style="flex:1">期望维修日期</text>
            <view>
                <text class="aaa"> {{dateTimeArray[0][dateTime[0]]}}-{{dateTimeArray[1][dateTime[1]]}}-{{dateTimeArray[2][dateTime[2]]}} {{dateTimeArray[3][dateTime[3]]}}:{{dateTimeArray[4][dateTime[4]]}}:{{dateTimeArray[5][dateTime[5]]}}</text>
            </view>
        </view>
    </picker>

js

var dateTimePicker = require('../../utils/dateTimePicker');
