 }



2、caculate方法，计算日历的天数与样式
　　1)将上个月的天数计算出来，本月第一天的星期不是星期天的话，就需要根据上个月的最后一天计算
　　2)将本月的天数遍历出来，如果是休息天就加上特殊的css样式
　　3)将下个月的天数计算出来，分三种情况，星期日、星期六和工作日

 function caculate($calendar) {
  $days = $calendar['days'];
  $firstDayOfWeek = $calendar['firstDayOfWeek'];//本月第一天的星期
  $lastDayOfWeek = $calendar['lastDayOfWeek'];//本月最后一天的星期
  $lastMonthOfLastDay = $calendar['lastMonthOfLastDay'];//上个月的最后一天
  $year = $calendar['year'];
  $month = $calendar['month'];
  
  $dates = array();
  if($firstDayOfWeek != 7) {
   $lastDays = array();
   $current = $lastMonthOfLastDay;//上个月的最后一天
   for ($i = 0; $i < $firstDayOfWeek; $i++) {
    array_push($lastDays, $current);//添加上一个月的日期天数
    $current--;
   }
   $lastDays = array_reverse($lastDays);//反序
   foreach ($lastDays as $index => $day) {
    array_push($dates, array('day' => $day, 'tdclass' => ($index ==0 "htmlcode">
