jqGrid扩展 重新加载表格数据，数据源从C#的webservice

先上代码：

$.jgrid.extend({    refresh: function (param) {        var $_t = $(this);        var defaults = { sortname: $_t.jqGrid("getGridParam", "sortname"), callback: null, url: '', postData: {}, isXls: false };        var opts = $.extend(defaults, param);        //param= $.extend( { sortname: '', callback: null, url: '' },param);        $("input[type='button']").prop("disabled", true);        var jsonReader = {};        if (opts.url.indexOf(".asmx") > -1) {            jsonReader = { root: "d.Table.rows", page: "d.Page", total: "d.Total", records: "d.Records", userdata: "d.Userdata" };        }        else {            jsonReader = { root: "rows", page: "page", total: "total", records: "records" };        }        var _loadPage = $_t.jqGrid("getGridParam", "page");        if (!_loadPage) _loadPage = 1;        $_t.jqGrid("setGridParam", {            url: opts.url, jsonReader: jsonReader,            datatype: "json", page: _loadPage, sortname: opts.sortname,            ajaxGridOptions: { contentType: 'application/json; charset=utf-8' },            postData: opts.postData,            gridComplete: function () {                if (param.callback) param.callback($_t);            },            loadComplete: function (data) {                if (param.loadComplete) param.loadComplete(data);            }        }).trigger("reloadGrid");        if (opts.isXls) {            $(".ui-pg-div:contains(导出)", $_t.jqGrid("getGridParam", "pager")).parent().remove();            $_t.jqGrid('navButtonAdd', $_t.jqGrid("getGridParam", "pager"), {                caption: "导出", onClickButton: function () {                    var _url = opts.url;                    if (opts.url.indexOf('?') > -1) _url += '&'; else _url += '?';                    if (_url.indexOf('isXls') > -1) { } else {                        _url += 'isXls=1&';                    }                    //colNames colModel 进行处理 传到服务端                    var _colNames = $_t.jqGrid("getGridParam", "colNames");                    var _colModel = $_t.jqGrid("getGridParam", "colModel");                    var _result = {};                    $.map(_colModel, function (item, k) {                        _result['xls_' + item.name] = _colNames[k];                    });                    _url = _url + $.param(_result);                    _url = _url + "&page=" + $_t.jqGrid("getGridParam", "page");                    _url = _url + "&rows=" + $_t.jqGrid("getGridParam", "rowNum");                    _url = _url + "&" + $.param(opts.postData);                    window.open(_url);                }            });        }        $("input[type='button']").prop("disabled", false);        $(".ui-jqgrid-bdiv div").css("position", "");    }});function loadFilter(data) {    /// <summary>jqGrid加载JSON数据时，对返回的data统一处理方式函数</summary>    /// <param name="data">json返回的JsonData对象</param>    /// <returns>无返回</returns>    if (!data.d) {        data.d = { Table: {} };    }    if (!data.d.Table) data.d.Table = {};    if (data.d.Total)        data.d.Table.total = data.d.Total;    else        data.d.Table.total = 0;    if (!data.d.Table.rows) data.d.Table.rows = [];    return data.d.Table;}

使用方法：

$("#tblList").jqGrid("refresh", { url: "/Task/Services/S_Task.asmx/GetLists?action='MyJoin'" + param ,isXls:false},callback:function(){

});

在使用jqGrid的时候，刷新加载服务端json数据，需要写很多代码，所以封装了这个方法，可以方便调用。

需要注意Framework要3.5以上。
