基于jquery封装的一个js分页

代码如下:

(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);

下边是调用方法：

代码如下:

function querylist(curpage) {
if (curpage == "" || curpage == null || curpage == undefined) {
curpage = 1;
}
var pagesize = 10;

var countys = $("#countys").val(); //县
var enddate = $("#enddate").val(); //结束时间
var begindate = $("#begindate").val(); //开始时间
$.ajax({
url: "",
type: "post",
data: { "countys": countys, "enddate": enddate, "begindate": begindate, "curpage": curpage, "pagesize": pagesize },
datatype: "json",
error: function (xhr, status, errmsg) { window.location.href = "/commonerror/index/" + errmsg.code + "?txt=" + errmsg.msg; },
success: function (mydata) {
var str = "";
$.each(mydata.tdata, function (i, item) {

str += "<tr>"
str += "<td>" + $.formatdatetime(item.controlbegintime, false) + "</td>";
str += "<td>" + $.formatdatetime(item.controlendtime, false) + "</td>";
str += "<td>" + item.name + "</td>";
str += "<td>" + item.platenumber + "</td>";
str += "<td>" + item.controldept + "</td>";
if (item.isall == "0") {
str += "<td>全县布控</td>";
}
else {
str += "<td>按卡口点布控</td>";
}
str += "<td>" + item.isall == "0" ? "全县布控" : "按卡口点布控" + "</td>";
str += "<td>修改</td>";
str += "<td>删除</td>";
str += "<td>详细</td>";
str + "</tr>";
});

$("#srh_rslt tbody").html(str);

$(".pagination").html($.pagefunc(mydata.total, pagesize, curpage, "querylist"));
}
});
}
