Atitit.列表页面and条件查询的实现最佳实践(2)------翻页 分页 控件的实现java .net php

 

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.. 1

2. 翻页的显示格式:: 1

2.1. 通常ui--“首页”、“上页”、“下页”、“末页”,还要有Goto到指定页 1

2.2. 百度式::...上一页567891011121314下一页 2

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

2.4.  2

3. 翻页器与数据源控件的交流数据.. 2

4. 分页/翻页的流程详细 2

4.1. :搜索框搜索按钮事件: 2

4.2. 翻页事件: 2

4.3. Jump事件... 2

5. 运行在服务端还是客户端控件?? 3

6. 数据源内部获得翻页数据运行在服务端还是客户端?? 3

7. 翻页控件选型::easyui 3

8. 翻页控件的扩展点and 调用点 3

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. 3

10. 数据源计算总记录的方法:::子能sql count()... 3

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..
