基于jquery封装的一个js分页

(function ($) { 
var PageFunc = function PageFunc() { } 
$.PageFunc = function (Total, PageSize, curPageNum, FunUrl) { 
if (PageSize == "" || PageSize == null || PageSize == undefined) { 
PageSize = 10; 
} 
if (curPageNum == "" || curPageNum == null || curPageNum == undefined) { 
curPageNum = 1; 
} 
//计算总页数 
Total = parseInt(Total); //总记录数 
PageSize = parseInt(PageSize); //每页显示数 
curPageNum = parseInt(curPageNum); //当前页 
//总页数 
var AllPage = Math.floor(Total / PageSize); 
if (Total % PageSize != 0) { 
AllPage++; 
} 

var navHtml = ""; 

if (curPageNum <= 0) 
curPageNum = 1; 
if (AllPage > 1) { 
if (curPageNum != 1) { 
//处理首页连接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('1')\" >|<</a></span> "; 
} 
if (curPageNum > 1) { 
//处理上一页的连接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('" + (curPageNum - 1) + "')\" ><<</a></span> "; 
} 
else { 
navHtml += "<span class=\"disabled\"><<</span> "; 
} 

var currint = 5; 
for (var i = 0; i <= 10; i++) { 
//一共最多显示10个页码，前面5个，后面5个 
if ((curPageNum + i - currint) >= 1 && (curPageNum + i - currint) <= AllPage) 
if (currint == i) { 
//当前页处理 
navHtml += "<span lass=\"current\">[" + curPageNum + "]</span> "; 
} 
else { 
//一般页处理 
var n = curPageNum + i - currint; 
navHtml += "<a href=\"javascript:" + FunUrl + "('" + (parseInt(n)) + "')\">" + n + "</a> "; 
} 
} 
if (curPageNum < AllPage) { 
//处理下一页的链接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('" + (parseInt(curPageNum) + 1) + "')\">>></a></span> "; 
} 
else { 
navHtml += "<span class=\"disabled\">>></span> "; 
} 

if (curPageNum != AllPage) { 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('" + AllPage + "')\" >>|</a></span>  "; 
} 

} 

navHtml += "<span>[" + curPageNum + "/" + AllPage + "]</span> "; 

return navHtml; 

}; 

})(jQuery); 

　　调用:

(function ($) { 
var PageFunc = function PageFunc() { } 
$.PageFunc = function (Total, PageSize, curPageNum, FunUrl) { 
if (PageSize == "" || PageSize == null || PageSize == undefined) { 
PageSize = 10; 
} 
if (curPageNum == "" || curPageNum == null || curPageNum == undefined) { 
curPageNum = 1; 
} 
//计算总页数 
Total = parseInt(Total); //总记录数 
PageSize = parseInt(PageSize); //每页显示数 
curPageNum = parseInt(curPageNum); //当前页 
//总页数 
var AllPage = Math.floor(Total / PageSize); 
if (Total % PageSize != 0) { 
AllPage++; 
} 

var navHtml = ""; 

if (curPageNum <= 0) 
curPageNum = 1; 
if (AllPage > 1) { 
if (curPageNum != 1) { 
//处理首页连接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('1')\" >|<</a></span> "; 
} 
if (curPageNum > 1) { 
//处理上一页的连接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('" + (curPageNum - 1) + "')\" ><<</a></span> "; 
} 
else { 
navHtml += "<span class=\"disabled\"><<</span> "; 
} 

var currint = 5; 
for (var i = 0; i <= 10; i++) { 
//一共最多显示10个页码，前面5个，后面5个 
if ((curPageNum + i - currint) >= 1 && (curPageNum + i - currint) <= AllPage) 
if (currint == i) { 
//当前页处理 
navHtml += "<span lass=\"current\">[" + curPageNum + "]</span> "; 
} 
else { 
//一般页处理 
var n = curPageNum + i - currint; 
navHtml += "<a href=\"javascript:" + FunUrl + "('" + (parseInt(n)) + "')\">" + n + "</a> "; 
} 
} 
if (curPageNum < AllPage) { 
//处理下一页的链接 
navHtml += "<span><a href=\"javascript:" + FunUrl + "('" + (parseInt(curPageNum) + 1) + "')\">>></a></span> ";
