這篇文章主要為大家詳細(xì)介紹了基于jquery編寫分頁(yè)插件的相關(guān)資料，感興趣的小伙伴們可以參考一下

擴(kuò)展JQuery很容易，作為一個(gè)練習(xí)，編寫一個(gè)簡(jiǎn)單的分頁(yè)插件，代碼量不大，直接看代碼好了：

$.fn.mypagination = function(totalProperty,opts){ 
  opts = $.extend({ 
    perPage:10, 
  
    callback:function(){ 
    } 
  },opts||{}); 
     
  return this.each(function(){ 
    function numPages(){ 
      return Math.ceil(totalProperty/opts.perPage); 
    } 
  
     
    function selectPage(page){ 
      return function(){ 
        currPage = page; 
        if (page<0) currPage = 0; 
        if (page>=numPages()) currPage = numPages()-1; 
        render(); 
  
        $('img.page-wait',panel).attr('src','images/wait.gif'); 
        opts.callback(currPage+1); 
        $('img.page-wait',panel).attr('src','images/nowait.gif'); 
      } 
    } 
     
    function render(){ 
  
      var html = '<table><tbody><tr>'  
        +'<td><a href="#"><img class="page-first"></a></td>' 
        +'<td><a href="#"><img class="page-prev"></a></td>' 
        +'<td><span>第<input type="text" class="page-num">頁(yè)/共'+numPages()+'頁(yè)</span></td>' 
        +'<td><a href="#"><img class="page-next"></a></td>' 
        +'<td><a href="#"><img class="page-last"></a></td>' 
        +'<td><img src="images/nowait.gif" class="page-wait"></td>' 
        +'<td><span style="padding-left:50px;">檢索到'+totalProperty+'記錄</span></td>' 
        +'</tr></tbody></table>'; 
      var imgFirst = 'images/page-first-disabled.gif'; 
      var imgPrev = 'images/page-prev-disabled.gif'; 
      var imgNext = 'images/page-next-disabled.gif'; 
      var imgLast = 'images/page-last-disabled.gif'; 
      if (currPage > 0){ 
        imgFirst = 'images/page-first.gif'; 
        imgPrev = 'images/page-prev.gif'; 
      } 
      if (currPage < numPages()-1){ 
        imgNext = 'images/page-next.gif'; 
        imgLast = 'images/page-last.gif'; 
      } 
      panel.empty(); 
      panel.append(html); 
      $('img.page-first',panel) 
        .bind('click',selectPage(0)) 
        .attr('src',imgFirst);  
      $('img.page-prev',panel) 
        .bind('click',selectPage(currPage-1)) 
        .attr('src',imgPrev);   
      $('img.page-next',panel) 
        .bind('click',selectPage(currPage+1)) 
        .attr('src',imgNext);   
      $('img.page-last',panel) 
        .bind('click',selectPage(numPages()-1)) 
        .attr('src',imgLast); 
      $('input.page-num',panel) 
        .val(currPage+1) 
        .change(function(){ 
          selectPage($(this).val()-1)(); 
        }); 
    } 
     
    var currPage = 0; 
    var panel = $(this); 
    render(); 
  
  }); 
}

下面測(cè)試一下：

<head> 
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
  <link rel="stylesheet" href="mypagination.css"/> 
  <script type="text/javascript" src="jquery-1.2.6.js"></script> 
  <script type="text/javascript" src="jquery.mypagination.js"></script> 
  <script> 
    $(document).ready(function(){ 
      $('#mypage').mypagination(10112,{ 
        callback:function(page){ 
          alert(page); 
        } 
      }); 
    }); 
  </script> 
</head> 
<div id="mypage" class="mypagination"></div>

運(yùn)行效果圖如下：
