Today, the editor will share with you the relevant knowledge points about how to achieve the Mini Program order Calendar plug-in. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article, let's take a look at it.

The plug-in is divided into two parts, the top is the tab bar, will automatically locate the current date according to the current date, and display the date of the next 7 days, the following is the content display, changing with the tab bar.

Train of thought:

First initialize the time with the new Data () time object, get the current date, and use new Date (Date.UTC (year, month-1, 1). GetDay () to get what day the first day of each month is.

/ / calculate what day the first day of each month is

Function getFirstDayOfWeek (year, month) {

Return new Date (Date.UTC (year, month-1,1). GetDay ()

}

Const date = new Date ()

Const cur_year = date.getFullYear ()

Const cur_month = date.getMonth () + 1

Const cur_date=date.getDate ()

Const weeks_ch = ['Day', 'one', 'two', 'three', 'four', 'five', 'six']

Use the constructor to generate data, which will be used later.

/ / create an object using the constructor

Function calendar (date,week) {

This.date=cur_year+'-'+cur_month+'-'+date

If (date==cur_date) {

This.week = "Today"

} else if (date==cur_date+1) {

This.week = "tomorrow"

} else {

This.week = 'week' + week

}

}

Use for loops to generate json data:

For (var iTunes 1 Ten i6) {

Xerox 0

}

/ / create an object using the constructor

That.data.calendar [I] = new calendar (I, [weeks_ ch [x]] [0])

Xerox +

}

Here, because there are 7 days in a week, when x > 6, reset to 0.

Finally, part of the source code is shown.

Var that=this

Function getThisMonthDays (year, month) {

Return new Date (year, month, 0). GetDate ()

}

/ / calculate what day the first day of each month is

Function getFirstDayOfWeek (year, month) {

Return new Date (Date.UTC (year, month-1,1). GetDay ()

}

Const date = new Date ()

Const cur_year = date.getFullYear ()

Const cur_month = date.getMonth () + 1

Const cur_date=date.getDate ()

Const weeks_ch = ['Day', 'one', 'two', 'three', 'four', 'five', 'six']

/ / create an object using the constructor

Function calendar (date,week) {

This.date=cur_year+'-'+cur_month+'-'+date

If (date==cur_date) {

This.week = "Today"

} else if (date==cur_date+1) {

This.week = "tomorrow"

} else {

This.week = 'week' + week

}

}

/ / number of days in the current month

Var monthLength= getThisMonthDays (cur_year, cur_month)

/ / what day is the first day of the current month?

Var week = getFirstDayOfWeek (cur_year, cur_month)

Var x = week

For (var iTunes 1 Ten i6) {

Xerox 0

}

/ / create an object using the constructor

That.data.calendar [I] = new calendar (I, [weeks_ ch [x]] [0])

Xerox +

}

/ / limit the number of calendar data days to be rendered within 7 days (user experience)

Var flag = that.data.calendar.splice (cur_date, that.data.calendar.length-cur_date
