Small Talk: The first day of the new year to work, looking at the end of their 15 years writing code, really feel very bad, because there is no time to write at the end, a thought to do backstage management need to get a week start and end date, panic, the project to test it, there are many things not done, Directly copied a section of the online error code, in fact, really simple, today re-spend some time to encapsulate, for later use, big God do not spray, thank you!

First, package for the jquery version of the date collection plug-in
Jquery.datecollections = (function(){    varNowdate =NewDate (); varClonenowdate =NewDate (); varFullyear =nowdate.getfullyear (); varmonth = Nowdate.getmonth () + 1;//the GetMonth method returns 0-11, representing January-December    varDate =nowdate.getdate (); varEndOfMonth =NewDate (fullyear, month, 0). GetDate ();//get the last day of the month    //formatted Date (2016-02-14)    functiongetfulldate (targetdate) {vard, Y, M, D; if(targetdate) {D=NewDate (targetdate); Y=d.getfullyear (); M= D.getmonth () + 1; D=d.getdate (); } Else{y=fullyear; M=month; D=date; } m= m > 9? M: ' 0 ' +m; D= d > 9? D: ' 0 ' +D; returnY + '-' + M + '-' +D; }    //Timestamp of the day (in milliseconds)    varTimestampofday = 1000*60*60*24; //Today, yesterday    varFulltoday =getfulldate (); varFullyesterday = Getfulldate (Nowdate-timestampofday); varNowday = Nowdate.getday ();//The GetDay method returns 0 for SundayNowday = Nowday = = = 0? 7: Nowday; //this Monday, the end of the week (Sunday)    //Note: Under Safari (Nowdate +-0) is not converted to a timestamp, where the operator + is preceded by the nowdate, and the timestamp operation is manually converted    varFullmonday = Getfulldate (+nowdate-(nowDay-1) *timestampofday); varFullsunday = getfulldate (+nowdate + (7-nowday) *timestampofday); //Early month, month end    varFullstartofmonth = Getfulldate (clonenowdate.setdate (1) ); varFullendofmonth =getfulldate (Clonenowdate.setdate (endOfMonth)); return{fulltoday:fulltoday, Fullyesterday:fullyesterday, Fullmonday:fullmonday, Fullsunday: Fullsunday, Fullstartofmonth:fullstartofmonth, fullendofmonth:fullendofmonth};} ());
Second, the package is a module, can be used for webpack tool packaging
varNowdate =NewDate ();varClonenowdate =NewDate ();varFullyear =nowdate.getfullyear ();varmonth = Nowdate.getmonth () + 1;//the GetMonth method returns 0-11, representing January-DecembervarDate =nowdate.getdate ();varEndOfMonth =NewDate (fullyear, month, 0). GetDate ();//get the last day of the month//formatted Date (2016-02-14)functiongetfulldate (targetdate) {vard, Y, M, D; if(targetdate) {D=NewDate (targetdate); Y=d.getfullyear (); M= D.getmonth () + 1; D=d.getdate (); } Else{y=fullyear; M=month; D=date; } m= m > 9? M: ' 0 ' +m; D= d > 9? D: ' 0 ' +D; returnY + '-' + M + '-' +D;}//Timestamp of the day (in milliseconds)varTimestampofday = 1000*60*60*24;//Today, yesterdayvarFulltoday =getfulldate ();varFullyesterday = Getfulldate (Nowdate-timestampofday);varNowday = Nowdate.getday ();//The GetDay method returns 0 for SundayNowday = Nowday = = = 0? 7: Nowday;//this Monday, the end of the week (Sunday)//Note: Under Safari (Nowdate +-0) is not converted to a timestamp, where the operator + is preceded by the nowdate, and the timestamp operation is manually convertedvarFullmonday = Getfulldate (+nowdate-(nowDay-1) *timestampofday);varFullsunday = getfulldate (+nowdate + (7-nowday) *timestampofday);//Early month, month endvarFullstartofmonth = Getfulldate (clonenowdate.setdate (1) );varFullendofmonth =getfulldate (Clonenowdate.setdate (EndOfMonth)); Module.exports={fulltoday:fulltoday, Fullyesterday:fullyesterday, Fullmonday:fullmonday, Fullsunday:fullsunday, Fullstartofmonth:fullstartofmonth, fullendofmonth:fullendofmonth};

Summary: code in two difficult points, one is to get the last day of the month's date, the second is to ask for a week's start and end date time, the 1th is not aware of the problem, the 2nd is compared today with the weekend (Sunday), Monday difference days, plus and minus the time stamp to obtain the corresponding date, in short said difficult, It is not difficult to say that it is possible to spend some time in your busy schedule and keep a clear mind;
