Question

我正在使用codeigniter。当我通过提供文件的完整路径来调用页面的ajax请求时，它可以正常工作：

    <!DOCTYPE html>
<html lang="en">
<head>
    <title id='Description'>In this example is demonstrated how to implement server filtering, sorting and paging with jqxGrid.</title>

        cache: false,

        filter: function()

            {
                source.totalrecords = data[0].TotalRows;                    
            }
        }
        };      
        var dataadapter = new $.jqx.dataAdapter(source, {
            loadError: function(xhr, status, error)
            {
                alert(error);
            }
        }
        );

        // initialize jqxGrid
        $("#jqxgrid").jqxGrid(
        {       
            source: dataadapter,
            width: "100%",
            filterable: true,
            sortable: true,
            autoheight: true,
            pageable: true,
            virtualmode: true,

            {
                return obj.data;    
            },
            columns: [
                { text: 'Ship Name', datafield: 'ShipName'},
                { text: 'Address', datafield: 'ShipAddress'},
                { text: 'City', datafield: 'ShipCity'},
                { text: 'Country', datafield: 'ShipCountry'}
            ]
        });
    });
    </script>
</head>
<body class='default'>
    <h1>Shipment Records</h1>
    <div style="width: 1000px" id="jqxgrid"></div>
</body>
</html>

可以正常使用

url: 'http://localhost/CodeIgniter_2.1.4/application/view/serverfiltering_paging_and_sorting_data.php',

但是

url: 'http://server/CodeIgniter_2.1.4/index.php/controllername/controlerfunction',

显示错误：SyntaxError：JSON.parse：意外字符

我没有在代码中做任何其他更改。

SyntaxError：JSON.parse：使用codeigniter调用ajax时出现意外字符
