The code is very simple, so I won’t go into too much nonsense, just give me the code:

Copy code The code is as follows:

/**

* * Realize that the current date is the first week of the year, and then push forward and backward by a few weeks 

* The js array stores the two weeks before and after the current date (a total of five weeks of data) 

**/

var initSearchMajorChanges = function(){

//Realize that the current date is the first week of the year, and then push forward and backward by a few weeks. The js array saves the two weeks before and after the current date (a total of five weeks of data)

      var vv='2015-02-07';

      var vNowDate=moment(new moment(vv).format("YYYY-MM-DD"));//.add('month',0).add('days',-1);

        var vWeekOfDay=moment(vNowDate).format("E");//Calculate the day of the week

      var vWeekOfDays=7-vWeekOfDay-1;

      var vStartDate=moment(vNowDate).add('days',vWeekOfDays);

      var vEndDate=moment(vNowDate).add('days',-vWeekOfDay);

      var vStartDateNew=moment(vStartDate).add('days',7*$scope.gWeeks);

        var vEndDateNew=moment(vEndDate).add('days',-(7*$scope.gWeeks));

//var vYearAndWeek=moment(vStartDate).format("YYYY") '-' moment(vStartDate).format("WW");

searchMajorChanges(vStartDateNew,vEndDateNew);

}
