How to implement the Mini Program order Calendar plug-in
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
