基于angular实现三级联动的生日插件

写了一个生日联动插件具体的效果是这样的：

具体的数据

我取得数据是今年的数据，如果是想要做三级联动的日期插件，改一下时间就好了

var app=angular.module("dataPicker",[])

app.factory('dataPicker', ['$http', '$q', function ($http, $q) {
  return {
   query: function () {
    var lengthYear=100;
    var dataPicker={
     month:[],
     year:[],
     day:[]
    };
    var data = new Date();
    var nowyear = data.getFullYear();
    for(var i=nowyear,j=0; i>nowyear-lengthYear;i--,j++){
     dataPicker.year[j]=i;
    }
    for(var i=0;i<=11;i++){
     if(i<9){
      dataPicker.month[i]='0'+(i+1);
     }else{
      dataPicker.month[i]=String(i+1);
     }
    }
    return dataPicker;
   }
  }
 }])

directive插件的主要内容

app.directive('selectDatepicker', function ($http,dataPicker) {
  return {
   restrict: 'EAMC',
   replace: false,
   scope: {
    birthday: '=birthday'
   },
   transclude: true,
   template: '<span>生日</span>'+
    '<select class="sel_year" ng-model="birY" ng-change="changeYear()"><option ng-repeat="x in yearAll">{{x}}</option></select>'+
    '<select class="sel_month" ng-model="birM" ng-change="changeMonth()" ng-disabled="birY==\'\'"><option ng-repeat="x in MonthAll">{{x}}</option> </select>'+
    '<select class="sel_day" ng-model="birD" ng-disabled="birM==\'\'" ng-change="changeDay()"><option ng-repeat="x in DayAll">{{x}}</option></select>',
   link: function (scope, element){
    var arr=[];
    scope.birthday=scope.birthday=='0000-00-00'?"":scope.birthday
    var shuju=dataPicker.query()
    scope.yearAll=shuju.year;
    scope.MonthAll=shuju.month;
    if(scope.birthday){
     scope.birY=scope.birthday.birthday.split('-')[0];
     scope.birM=String(scope.birthday.birthday.split('-')[1])
    }else{
     scope.birY="";
     scope.birM="";
    }
    scope.getDaysInOneMonth=function(year, month){
     var month1 = Number(month);
     month1=parseInt(month1,10)
     var d= new Date(Number(year),month1,0);
     return d.getDate();
    }
    scope.getDayArr=function(day){
     shuju.day=[];
     for(var i=0; i<day;i++){
      if(i<9){
       shuju.day[i]='0'+(i+1)
      }else{
       shuju.day[i]=String((i+1));
      }
     }
    }
    if(scope.birthday){
     var day=scope.getDaysInOneMonth(scope.birthday.birthday.split('-')[0],scope.birthday.birthday.split('-')[1]);
     scope.getDayArr(day)
     scope.DayAll=shuju.day;
     scope.birD=scope.birthday.birthday.split('-')[2]
    }
    scope.changeYear=function(){
     scope.birD="";
     scope.birM="";
    }
    scope.changeMonth=function(){
     var day=scope.getDaysInOneMonth(scope.birY,scope.birM);
     console.log(day)
     scope.getDayArr(day);
     scope.DayAll=shuju.day;
     scope.birD="";
    }
    scope.changeDay=function(){
     scope.returnDate();
    }
    scope.returnDate=function(){
     if(!scope.birD||!scope.birY||!scope.birM){
      scope.birthday.returnValue="";
     }else{
      arr[0]=scope.birY;
      arr[1]=scope.birM;
      arr[2]=scope.birD;
      scope.birthday.returnValue=arr.join("-");
     }
    }
   }
  }
 })
});
