jQuery+PHP发布的内容进行无刷新分页(Fckeditor),jqueryfckeditor

这篇文章将使用jQuery,并结合PHP,将Fckeditor发布的内容进行分页,并且实现无刷新切换页面。
 本文假设你是WEB开发人员,掌握了jQuery和PHP相关知识,并且熟知Fckeditor的配置和使用。
Fckeditor编辑器有一个插入分页符的功能按钮,点击该按钮,将会在内容区插入一条分页符,如下图红色框标注:

分页符对应生成的html代码是:

<div style="page-break-after: always"><span style="display: none"> </span></div> 
Copy after login

我们实际应用情况是这样的:后台通过Fckeditor编辑器发布的内容,提交到数据库,前台通过PHP链接数据库获取发布的内容,然后将长内容进行分割,并进行分页。
PHP
PHP将内容分割的方法如下:

function pageBreak($content){ 
 $content = $content; 
 $pattern = "/<div style=\"page-break-after: always\"><span style=\"display: none\"> 
<\/span><\/div>/"; 
 $strSplit = preg_split($pattern, $content, -1, PREG_SPLIT_NO_EMPTY); 
 $count = count($strSplit); 
 $outStr = ""; 
 $i  = 1; 
 
 if ($count > 1 ) { 
  $outStr = "<div id='page_break'>"; 
  foreach($strSplit as $value) { 
   if ($i <= 1) { 
    $outStr .= "<div id='page_$i'>$value</div>"; 
   } else { 
    $outStr .= "<div id='page_$i' class='collapse'>$value</div>"; 
   } 
   $i++; 
  } 
 
  $outStr .= "<div class='num'>"; 
  for ($i = 1; $i <= $count; $i++) { 
   $outStr .= "<li>$i</li>"; 
  } 
  $outStr .= "</div></div>"; 
  return $outStr; 
 } else { 
  return $content; 
 } 
}
Copy after login

可以看出啦,上述代码中的$pattern就是Fckeditor编辑器生成的分页符代码,然后PHP通过preg_split()函数比对内容,以分隔符为分界点,将内容分割为多个page_,并且生成分页导航按钮。使用时只需调用pageBreak($content)即可。
CSS
我们通过CSS来呈现分页按钮的风格,当然你可以修改这些CSS,定制你想要的外观。

#page_break {} 
#page_break .collapse {display: none;} 
#page_break .num {padding: 10px 0;text-align: center;} 
#page_break .num li{display: inline; margin: 0 2px;padding: 3px 5px;border:1px solid #abcee4; 
background-color: #fff;color: #369;text-align: center;cursor: pointer;overflow: hidden;} 
#page_break .num li.on{background-color: #369;color: #fff;font-weight: bold;} 
Copy after login

jQuery

$(function(){ 
 $('#page_break .num li:first').addClass('on'); 
 
 $('#page_break .num li').click(function(){ 
  //隐藏所有页内容 
  $("#page_break div[id^='page_']").hide(); 
 
  //显示当前页内容。 
  if ($(this).hasClass('on')) { 
   $('#page_break #page_' + $(this).text()).show(); 
  } else { 
   $('#page_break .num li').removeClass('on'); 
   $(this).addClass('on'); 
   $('#page_break #page_' + $(this).text()).fadeIn('normal'); 
  } 
 }); 
}); 
Copy after login

我们使用jQuery将分页导航按钮的第一页设置为当前状态,然后通过单击分页按钮,切换按钮的状态,并且显示对应页的内容。
顺便说一下,文章标题说的是无刷新,其实这不是Ajax的无刷新效果,而是通过jQuery控制页面内容的显示与隐藏,页面内容是一次性读取载入的。

关于jquery无刷新分页有许多文章,大家可以搜搜之前的文章,或许会有更大的启发。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
