HomeBackend DevelopmentPHP TutorialthinkPHP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:

复制代码 代码如下:
 
 
 
 
Insert title here 
 
 
 
 
 
 
 
 
 
 
 
 
 
瀑布流下来了
 
 
 
 
 
 
 
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:

复制代码 代码如下:
//初始化的数据 
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。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
