当前日期格式化

function CurentTime()
    { 
        var now = new Date();
        var year = now.getFullYear();       //年
        var month = now.getMonth() + 1;     //月
        var day = now.getDate();            //日
        var hh = now.getHours();            //时
        var mm = now.getMinutes();          //分
        var ss = now.getSeconds();
        var clock = year+"";        //加""的作用是转成字符串，不然会以整型计算
        if(month < 10)
            clock += ""+"0";       
        clock += month;
        if(day < 10)
            clock += ""+"0";           
        clock += day;
        if(hh < 10)
            clock += ""+"0";          
        clock += hh;
        if (mm < 10)
            clock += ""+"0"; 
        clock += mm; 
        if (ss < 10)
            clock += ""+"0"; 
        clock += ss;
        return(clock); 
    }    
    $scope.time='当前日期时间为：'+CurentTime();

获取

function GetDateStr(AddDayCount) {
           var dd = new Date();
           dd.setDate(dd.getDate()+AddDayCount);//获取AddDayCount天后的日期
           var y = dd.getFullYear();
           var m = dd.getMonth()+1;//获取当前月份的日期
           var d = dd.getDate();
           return y+"."+m+"."+d;
           }
   $scope.zuotian = GetDateStr(-1);//昨天
   var date_ = new Date();  
   var year = date_.getFullYear();  
   var month = date_.getMonth() + 1;  
   $scope.firstdate = year + '.' + month + '.01';//当月第一天
   var day = new Date(year,month,0);      
   $scope.lastdate = year + '.' + month + '.' + day.getDate();//当月最后一天
