Learn to write jsCalender calendar controls together

This article mainly describes jsCalender controls and writes a simple calendar control by yourself. Interested friends can refer to some functions about js date recently, I suddenly thought of the calendar control, so I tried to write one. As a background programmer, I have a limited level. Let's take a look at the example I wrote and learn and make progress together!

First, a common date function:

Date (year, month, day)

Var date = new Date ();

Get year

Var year = this. date. getFullYear ();

Obtain the month. Here is the monthly index, so we need to add 1 more.

Var month = this. date. getMonth () + 1;

Obtain the number of the current day

Var day = this. date. getDate ();

Returns the day of the week. 0. Sunday 1. Monday 2. Tuesday 3. Wednesday 4. Thursday 5. Friday 6. Saturday.

Var week = this. date. getDay ();

Obtain the number 1 of the week in the current month.

var   getWeekDay=function(year,month,day){     var date=new Date(year,month,day);     return date.getDay();     } 　　var  weekstart= getWeekDay(this.year, this.month-1, 1)

Obtain the number of days in the current month

var getMonthDays=function(year,month){      var date=new Date(year,month,0);      return date.getDate();    }var  monthdays= this.getMonthDays(this.year,this.month);

Well, we have used so many parameters. The following are some operations and judgments on the day of the week corresponding to the date, and dynamic tag splicing. The example I wrote is directly sent below:
