1. 关于翻页有关的几大控件::搜索框控件,显示表格控件,翻页器,数据源控件..
2. 翻页的显示格式::
2.1. 通常ui--“首页”、“上页”、“下页”、“末页”,还要有Goto到指定页
“首页”、“上页”、“下页”、“末页”,还要有Goto到指定页等等
当前页/总页数 总条数 指定pagesize选择器
2.2. 百度式::...2.3. 综合的页面 首页”、“上页”、56789 “下页”、“末页”,还要有Goto到指定页
2.4.
优缺点::
3. 翻页器与数据源控件的交流数据..
翻页器 pre ,next页面事件,,,会传出数据:::: pagesize,page...
数据源会返回数据:: rows(记录总数) , datalist..(当前页的数据)
4. 分页/翻页的流程详细
4.1. :搜索框搜索按钮事件:
获得搜索框参数>>传给翻页器>>指定翻页器当前页面为1>>> 翻页器执行查询>>数据源>》》获得显示数据绑定显示在表格控件中...>>按照返回的记录计算翻页器的总页数...>>翻页器设置嘎自的 首页”、“上页”为禁用状态..
或者
搜索框控件获得参数>>直接执行查询pagesize,page=1>>数据源>》》获得显示数据绑定显示在表格控件中...>>按照返回的记录计算翻页器的总页数.>>>指定翻页器当前页面为1>>翻页器设置嘎自的 首页”、“上页”为禁用状态..
4.2. 翻页事件:
翻页器计算(+-或者goto 第一的页or最后的页面) 要使用的页数>>执行从 搜索框控件获得参数>>参数传给数据源控件>>>返回翻页数据..>>绑定显示在表格控件中..>>>按照返回的记录计算翻页器的总页数>>>>翻页器设置嘎自的 首页”、“上页”“下页”、“末页”为禁用状态..
4.3. Jump事件...
5. 运行在服务端还是客户端控件??
从兼容性考虑, 翻页控件还是运行在客户端更好...java .net php都能使用....
6. 数据源内部获得翻页数据运行在服务端还是客户端??
从开发效率想, 少量数据可以在客户端数据源内部获得...
7. 翻页控件选型::easyui
客户端easyui 推荐,,,...Ligerui的根本马独立的翻页控件
服务端:: 倒霉,几乎马知名的分页控件,只好嘎自写兰..
aspnetpager
8. 翻页控件的扩展点and 调用点
扩展点:::一个接口,用来调用外部控件...
var onSelectPage= function(pageNumber, pageSize){
//$('#content').panel('refresh', 'show_content.php?page='+pageNumber);
query();
}
调用点:::外部控件可以调用的翻页控件方法..
resetPageTo1()
9. 容器注射DI,IOC绑定搜索控件and翻页控件and数据源and表格控件.
10. 数据源计算总记录的方法:::子能sql count()...
或者使用server 翻页而不是数据库翻页..
