如下：

{qb:tag name='list_fqhaibao_02' type='cms' mid='10' rows='3' where='hbtype=$hbtype'}

与

{qb:tag name='list_fqhaibao_02' type='cms' mid='10' rows='3' union='hbtype'}

在使用如下ajax：

var url= "{qb:url name='list_fqhaibao_02'}" + page + "&hbtype=" + index;

获取到的数据有明显差异，

{qb:tag name='list_fqhaibao_02' type='cms' mid='10' rows='3' where='hbtype=$hbtype'}

这种写法get到的数据更加准确.此坑踩了好久
