 1 //"总条数"：rowCount，"每页总条数"：pageSize
 2 pageTotal(rowCount, pageSize) {  
 3        if (rowCount == null || rowCount == "") {
 4              return 0;
 5        } else {
 6              if (pageSize != 0 && rowCount % pageSize == 0) {
 7                     return parseInt(rowCount / pageSize                  
 8              }
 9              if (pageSize != 0 && rowCount % pageSize != 0) {
10                     return parseInt(rowCount / pageSize) + 1;
11              }
