thinkPHP实现瀑布流的方法_php实例
本文实例讲述了thinkPHP实现瀑布流的方法。分享给大家供大家参考。具体分析如下:
很多人都想做瀑布流的效果,这里告诉大家官网使用的方法,首先要下载瀑布流的插件jquery.masonry.min.js 地址:http://masonry.desandro.com/index.html里面包含的很多示例.
流程:
1. 页面初始化时,调用插件进行一次排版;
2. 当用户将滚动条拖到底部时,用ajax加载一次数据,并排版显示
3. 重复2,直到无数据
Html代码:
加载中,请稍后...
});
var $newElems = $(html).css({ opacity: 0 }).appendTo($container);
$newElems.imagesLoaded(function(){
$newElems.animate({ opacity: 1 });
$container.masonry( 'appended', $newElems, true );
});
//一次请求完成,将on设为false,可以进行下一次的请求
loading.data("on", false);
}
loading.fadeOut();
},
"json"
);
}
});
});
Action代码:
public function lists(){
$data = D('Info')->order('id DESC')->limit(10)->select();
$this->assign('data', $data);
$this->display();
}
//获取一次请求的数据
public function getMore(){
//获取最后一个id
if(!emptyempty($_GET['lastid']))$map['id'] = array('lt', $_GET['lastid']);
$data = D('Info')->where($map)->order('id DESC')->limit(10)->select();
$this->ajaxReturn($data);
}
注意:通过判断窗口是否滚动到页面底部来决定用ajax加载一次数据,如果不做处理,会一下子请求很多次,所以,要使用条件来限制.
这里使用的是往一个元素上赋值 $("#loading").data("on", true);,在请求期间判断是true则不继续请求,然后在页面请求完成后再赋值为false.
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。

Performance comparison of Laravel and ThinkPHP frameworks: ThinkPHP generally performs better than Laravel, focusing on optimization and caching. Laravel performs well, but for complex applications, ThinkPHP may be a better fit.

"Development Suggestions: How to Use the ThinkPHP Framework to Implement Asynchronous Tasks" With the rapid development of Internet technology, Web applications have increasingly higher requirements for handling a large number of concurrent requests and complex business logic. In order to improve system performance and user experience, developers often consider using asynchronous tasks to perform some time-consuming operations, such as sending emails, processing file uploads, generating reports, etc. In the field of PHP, the ThinkPHP framework, as a popular development framework, provides some convenient ways to implement asynchronous tasks.

ThinkPHP installation steps: Prepare PHP, Composer, and MySQL environments. Create projects using Composer. Install the ThinkPHP framework and dependencies. Configure database connection. Generate application code. Launch the application and visit http://localhost:8000.

ThinkPHP is a high-performance PHP framework with advantages such as caching mechanism, code optimization, parallel processing and database optimization. Official performance tests show that it can handle more than 10,000 requests per second and is widely used in large-scale websites and enterprise systems such as JD.com and Ctrip in actual applications.

Development suggestions: How to use the ThinkPHP framework for API development. With the continuous development of the Internet, the importance of API (Application Programming Interface) has become increasingly prominent. API is a bridge for communication between different applications. It can realize data sharing, function calling and other operations, and provides developers with a relatively simple and fast development method. As an excellent PHP development framework, the ThinkPHP framework is efficient, scalable and easy to use.
