Small Program (18) picker component details, small program picker

Picker selectors are divided into three types: Common selector and time selector. The date selector is distinguished by the mode attribute. The default value is normal selector. During the test, the time and date click did not respond. I don't know if it's a BUG or something! No way to test the phone. I don't know what's going on now !!

Main attributes:

Common Selector

Time Selector

Date Selector

Wxml

<View> normal selector </view> <! -- Mode: index bindchange event listener selected by default for selector range data source value --> <picker mode = "selector" range = "{array}" value = "{index }}" bindchange = "listenerPickerSelected"> <text >{{ array [index] }}</text> </picker> <view> time selector </view> <picker mode = "time "value =" {time }}" start = "06:00" end = "24:00" bindchange = "listenerTimePickerSelected"> <text >{{ time }}</text> </ picker> <view> date selector </view> <picker mode = "date" value = "{date}" start = "2016-09-26" end = "2017-10-10" bindchange =" listenerDatePickerSelected "> <text >{{ date }}</text> </picker>
