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..

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
