  • mvc中使用Pagination,对其进行再封装

    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:

    使用ajax请求部分视图:

        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr>
                <td>@item.Id</td>
                <td>@item.Name</td>

            </tr> 
        }
    </tbody>
    </table>
    <p>pageIndex:@ViewBag.pageIndex</p>

    控制器:
