本文实例为大家分享了jquery.pager.js分页实现代码，供大家参考，具体内容如下

jquery.pager.js：

 
(function($) { 
 
 $.fn.pager = function(options) { 
 
 var opts = $.extend({}, $.fn.pager.defaults, options); 
 
 return this.each(function() { 
 
 // empty out the destination element and then render out the pager with the supplied options 
  $(this).empty().append(renderpager(parseInt(options.pagenumber), parseInt(options.pagecount), options.buttonClickCallback)); 
  
  // specify correct cursor activity 
  $('.pages li').mouseover(function() { document.body.style.cursor = "pointer"; }).mouseout(function() { document.body.style.cursor = "auto"; }); 
 }); 
 }; 
 
 // render and return the pager with the supplied options 
 function renderpager(pagenumber, pagecount, buttonClickCallback) { 
 
 // setup $pager to hold render 
 var $pager = $('
'); 
 
 // add in the previous and next buttons 
 $pager.append(renderButton('第一页', pagenumber, pagecount, buttonClickCallback)).append(renderButton('上一页', pagenumber, pagecount, buttonClickCallback)); 
 
 // pager currently only handles 5 viewable pages ( could be easily parameterized, maybe in next version ) so handle edge cases 
 var startPoint = 1; 
 var endPoint = 5; 
 
 if (pagenumber > 2) { 
  startPoint = pagenumber - 2; 
  endPoint = pagenumber + 2; 
 } 
 
 if (endPoint > pagecount) { 
  startPoint = pagecount - 3; 
  endPoint = pagecount; 
 } 
 
 if (startPoint < 1) { 
  startPoint = 1; 
 } 
 
 // loop thru visible pages and render buttons 
 for (var page = startPoint; page <= endPoint; page++) { 
 
  var currentButton = $('
' + (page) + '
'); 
 
  page == pagenumber ? currentButton.addClass('pgCurrent') : currentButton.click(function() { buttonClickCallback(this.firstChild.data); }); 
  currentButton.appendTo($pager); 
 } 
 
 // render in the next and last buttons before returning the whole rendered control back. 
 $pager.append(renderButton('下一页', pagenumber, pagecount, buttonClickCallback)).append(renderButton('尾页', pagenumber, pagecount, buttonClickCallback)); 
 
 return $pager; 
 } 
 
 // renders and returns a 'specialized' button, ie 'next', 'previous' etc. rather than a page number button 
 function renderButton(buttonLabel, pagenumber, pagecount, buttonClickCallback) { 
 
 var $Button = $('
' + buttonLabel + '
'); 
 
 var destPage = 1; 
 
 // work out destination page for required button type 
 switch (buttonLabel) { 
  case "第一页": 
  destPage = 1; 
  break; 
  case "上一页": 
  destPage = pagenumber - 1; 
  break; 
  case "下一页": 
  destPage = pagenumber + 1; 
  break; 
  case "尾页": 
  destPage = pagecount; 
  break; 
 } 
 
 // disable and 'grey' out buttons if not needed. 
 if (buttonLabel == "第一页" || buttonLabel == "上一页") { 
  pagenumber <= 1 ? $Button.addClass('pgEmpty') : $Button.click(function() { buttonClickCallback(destPage); }); 
 } 
 else { 
  pagenumber >= pagecount ? $Button.addClass('pgEmpty') : $Button.click(function() { buttonClickCallback(destPage); }); 
 } 
 
 return $Button; 
 } 
 
 // pager defaults. hardly worth bothering with in this case but used as placeholder for expansion in the next version 
 $.fn.pager.defaults = { 
 pagenumber: 1, 
 pagecount: 1 
 }; 
 
})(jQuery);
