js获取当前一周的日期和星期

     var bbb7= new Array();

         //获取最近7天日期
         bbb7.push(getDay(0)+xingqi(0));//当天日期
         bbb7.push(getDay(-1)+xingqi(1));
         bbb7.push(getDay(-2)+xingqi(2));

         bbb7.push(getDay(-4)+xingqi(4));
         bbb7.push(getDay(-5)+xingqi(5));
         bbb7.push(getDay(-6)+xingqi(6));
