WeChat applet selector (time, date, region)

WeChat applet development Since I have recently learned the development of WeChat applet, based on my own practical results I have sorted out the results and found some examples of date selector, time selector, and region selector. If there are any mistakes, I hope you can correct them.

The controls packaged in WeChat envelopes feel very good and save us developers a lot of trouble. The disadvantage is that we cannot do a lot of customization. I tried the selector today.

①Ordinary selector

The selector is distinguished by mode. The default is the ordinary selector, e.detail The value obtained by .value is the index index of the selected item, and then the value is obtained through the array. When initializing the data, just add the alternative item to the array.

bindPickerChange is triggered when selecting Event, get index.

②Time selector

When mode = time, it is the time selector. start and end are the beginning of the valid time range respectively. and end.Format hh:mm
Trigger bindTimeChange event when selecting, get time.

③Date selector

mode = date, yes Time selector. start and end are the start and end of the valid date range respectively. The bindDateChange event is triggered when the format yyyy-MM-dd
is selected, and the date

is obtained. The above is the entire content of this article. I hope it will be helpful to everyone’s learning. For more related content, please pay attention to the PHP Chinese website!
