pg:pager【这个标签用来设置分页的总体参数】重要参数说明:
url:分页的链接根地址,pager标签会在这个链接的基础上附加分页参数
items:总记录数,pager标签正是根据这个值来计算分页参数的
maxPageItems:每页显示的行数,默认为10
maxIndexPages:在循环输出页码的时候,最大输出多少个页码,默认是10
pg:first【第一页的标签】重要参数说明:
export变量的意义:
pageUrl - 分页链接URL地址(最重要的export参数)
pageNumber - 页码
firstItem - 首页第一行的索引值
lastItem - 首页最后一行的索引值
pg:pre【上一页标签】重要参数说明:
export变量的意义:
pageUrl - 分页链接URL地址(最重要的export参数)
pageNumber - 页码
firstItem - 前页第一行的索引值
lastItem - 前页最后一行的索引值
pg:next【下一页标签】重要参数说明:
export变量的意义:
pageUrl - 分页链接URL地址(最重要的export参数)
pageNumber - 页码
firstItem - 下页第一行的索引值
lastItem - 下页最后一行的索引值
pg:last【最后一页的标签】重要参数说明:
export变量的意义:
pageUrl - 分页链接URL地址(最重要的export参数)
pageNumber - 页码
firstItem - 尾页第一行的索引值
lastItem - 尾页最后一行的索引值
pg:pages【这个标签用来循环输出页码信息】重要参数说明:
export变量的意义:
pageUrl - 分页链接URL地址(最重要的export参数)
pageNumber - 页码
firstItem - pageNumber这个页码指定的那一页的第一行的索引值
lastItem - pageNumber这个页码指定的那一页的最后一行的索引值
