对其进行再次封装:

(function($) {
            $["fn"]["easyPaging"] = function(o) {
                if (!o.pageSelect ||!$["fn"]["pagination"]) {
                    return this;
                }               
                var num = o.num || 50;                
                var opts = {
                    "items_per_page": 10,
                    "num_display_entries": 5,
                    "num_edge_entries": 1,
                    "prev_text": "< 上一页",
                    "next_text": "> 下一页",                   
                    "callback": function(page_index, jq) {}
                };
                $["extend"](opts, o || {});

                opts.callback = function(page_index, jq){
                    var select = o.pageSelect;         
                    var max_elem = Math.min((page_index+1) * opts.items_per_page, num);
                    select(page_index + 1, page_index * opts.items_per_page, max_elem);
                    return false;
                }
                var sumPage = Math.ceil(num/opts.items_per_page);
                opts.bindclick = function(pageSelected){
                    $("#hx_getPageData").on("click",function(evt){
                        var hxpageIndex = $.trim($("#hx_pageIndex").val());
                        if(hxpageIndex.length == 0 || hxpageIndex <= 0)
                        {
                            hxpageIndex = 1;
                            $("#hx_pageIndex").val(1);
                        }
                        if(hxpageIndex > sumPage)
                        {
                            hxpageIndex = sumPage;
                            $("#hx_pageIndex").val(hxpageIndex);
                        }
                        pageSelected(hxpageIndex-1,evt);
                    });
                }                
                var othertext = ‘<span>共‘ + sumPage + ‘页,去第</span><input type="text" id="hx_pageIndex" />页
<input type="button" id="hx_getPageData" value="确定" />‘; var thisObj = $(this); $(othertext).insertAfter(thisObj); thisObj.pagination(o.num, opts); }; }(jQuery));

使用方式:

        function pageSelect(pindex, start,end){              
            $.get( ‘@Url.Action("PersonDetail", "PageTest")‘+‘?pindex=‘ + pindex + "&start=" + start + "&end=" + end,
            function(data) {
                $(‘#Searchresult‘).html(data);
            });
            return false;
        }
        $(document).ready(function(){

            $("#Pagination").easyPaging({num:195,pageSelect:pageSelect});
        });

整个页面:

@section css
{
    <link href="@Url.Content("~/Scripts/Pagination/Pagination.css")" rel="stylesheet" type="text/css" />
    
}

<div id="Pagination" class="pagination"></div>
<br style="clear:both;"/>
<h3>List of former members of the United States House of Representatives (A)</h3>
<div id="Searchresult"></div>
@section script{
   <script src="@Url.Content("~/Scripts/Pagination/myPagination.js?v=11")" charset="UTF-8" type="text/javascript"></script> 
   <script type="text/javascript">
           (function($) {
            $["fn"]["easyPaging"] = function(o) {
                if (!o.pageSelect ||!$["fn"]["pagination"]) {
                    return this;
                }               
                var num = o.num || 50;                
                var opts = {
                    "items_per_page": 10,
                    "num_display_entries": 5,
                    "num_edge_entries": 1,
                    "prev_text": "< 上一页",

                };
                $["extend"](opts, o || {});

                opts.callback = function(page_index, jq){
                    var select = o.pageSelect;         
                    var max_elem = Math.min((page_index+1) * opts.items_per_page, num);
                    select(page_index + 1, page_index * opts.items_per_page, max_elem);
                    return false;
                }
                var sumPage = Math.ceil(num/opts.items_per_page);
                opts.bindclick = function(pageSelected){
                    $("#hx_getPageData").on("click",function(evt){
                        var hxpageIndex = $.trim($("#hx_pageIndex").val());
                        if(hxpageIndex.length == 0 || hxpageIndex <= 0)
                        {
                            hxpageIndex = 1;
                            $("#hx_pageIndex").val(1);
                        }
                        if(hxpageIndex > sumPage)
                        {
                            hxpageIndex = sumPage;
                            $("#hx_pageIndex").val(hxpageIndex);
                        }
                        pageSelected(hxpageIndex-1,evt);
                    });
                }

使用ajax请求部分视图:

@model List<MvcApp.Models.Person>

<table>
<thead>
    <tr>
        <td>Id</td>
        <td>Name</td>
        <td>NicName</td>
        <td>Tel</td>
    </tr>
</thead>
<tbody>
    @foreach (var item in Model)
    {
        <tr>
            <td>@item.Id</td>
            <td>@item.Name</td>
            <td>@item.NicName</td>
            <td>@item.Tel</td>
        </tr> 
    }
</tbody>
</table>
<p>pageIndex:@ViewBag.pageIndex</p>

控制器:

        public ActionResult PersonDetail(int pindex)
        {
            ViewBag.pageIndex = pindex;
            return PartialView(GetDatas());
        }
        public List<Person> GetDatas()
        {
            return new List<Person>
            {
                new Person{Id=1,Name="ly1",NicName="llllyyyy",Tel="135"},
                new Person{Id=2,Name="ly2",NicName="llllyyyy",Tel="135"},
                new Person{Id=3,Name="ly3",NicName="llllyyyy",Tel="135"},
                new Person{Id=4,Name="ly4",NicName="llllyyyy",Tel="135"},
                new Person{Id=5,Name="ly5",NicName="llllyyyy",Tel="135"},
                new Person{Id=6,Name="ly6",NicName="llllyyyy",Tel="135"},
                new Person{Id=7,Name="ly7",NicName="llllyyyy",Tel="135"},

        }
        // When all initialisation is done, draw the links
        drawLinks();
        // call callback function
        opts.callback(current_page, this);
        opts.bindclick(pageSelected);        
    });
}

css:

.pagination {
            font-size: 80%;
        }
        
.pagination a {
    text-decoration: none;
    border: solid 1px #AAE;
    color: #15B;
}

.pagination a, .pagination span {
    display: block;
    float: left;
    padding: 0.3em 0.5em;
    margin-right: 5px;
    margin-bottom: 5px;
}

.pagination .current {
    background: #26B;
    color: #fff;
    border: solid 1px #AAE;
}

.pagination .current.prev, .pagination .current.next{
    color:#999;
    border-color:#999;
    background:#fff;
}

 

mvc中使用Pagination,对其进行再封装
