Question

我现在空白，回答为什么这不起作用。基本上，最终结果是一个没有抛出Javascript或XHR错误的空白网格。

Javascript代码：

var MyServiceURL = "MyService.asmx/";

function getOrders() {
    $.ajax({
        type: "POST",
        dataType: "json",
        url: MyServiceURL + 'GetOrders',
        success: function(data) {
            var thegrid = $("#orders")[0];
            thegrid.addJSONData(data);
        },
        error: function(e) {
            var error = $.parseJSON(e.responseText);
            $('#msg').html(error.Message);
        }
    });
}

function bindGrid() {
    $("#orders").jqGrid({
        datatype: getOrders,
        colNames: ['CO_ODNO', 'CO_STATUS', 'ROUTE_CODE', 'ROUTE_STOP', 'PRIOR_NAME', 'CU_NO'],
        colModel: [{ name: 'CO_ODNO', index: 'CO_ODNO', width: 200, align: 'left' },
                   { name: 'CO_STATUS', index: 'CO_STATUS', width: 200, align: 'left' },
                   { name: 'ROUTE_CODE', index: 'ROUTE_CODE', width: 200, align: 'left' },
                   { name: 'ROUTE_STOP', index: 'ROUTE_STOP', width: 200, align: 'left' },
                   { name: 'PRIOR_NAME', index: 'PRIOR_NAME', width: 200, align: 'left' },
                   { name: 'CU_NO', index: 'CU_NO', width: 200, align: 'left' }
                   ],
        rowNum: 10,
        rowList: [5, 10, 20, 50, 100],
        sortname: 'CO_ODNO',
        pager: $('#pager'),
        sortorder: "desc",
        viewrecords: true
    });


}

$(document).ready(function() {

    $.ajaxSetup({
        type: "POST",
        cache: false,
        contentType: "application/json; charset=utf-8",
        data: "{}",
        dataFilter: function(data) {
            var msg;

            if (typeof (JSON) !== 'undefined' &&
            typeof (JSON.parse) === 'function')
                msg = JSON.parse(data);
            else
                msg = eval('(' + data + ')');

            if (msg.hasOwnProperty('d'))
                return msg.d;
            else
                return msg;
        }
    });

    $('#btnGetOrders').click(function() {
        bindGrid();
    });

});

从服务器返回的数据（使用JSON Lint验证）：

我无法将屏幕截图发布为新用户，但这些列已正确创建并显示为空白。

任何帮助解决此问题的人都将不胜感激！

谢谢，

如果我觉得你犯了同样的错误，比如here。

首先，我想在web方法GetOrders中使用JavaScriptSerializer来对象进行序列化，该对象代表网格行，服务返回string。结果，数据（字符串）的JSON表示将添加到具有d属性{d:result}的对象中，并且所有再次转换为JSON。而不是你的web方法应该只返回List<Order>类型。您可以验证这是否会使用thegrid.addJSONData(jQuery.parseJSON(data.d))代替thegrid.addJSONData(data)

我建议您也不要使用$.ajaxSetup，$.ajax和$("#orders").jqGrid的复杂结构作为函数datatype。在引入ajaxGridOptions和serializeGridData选项之前，这对jqGrid很有用。在jqGrid 3.6及更高版本中，jqGrid可以直接从几乎任何数据源加载数据。有关详细信息和代码示例，请参阅the answer（this，this）中的链接。您还可以搜索ajaxGridOptions and serializeGridData`。
