jqGrid初始化加载本地json数据

$(function(){  

    $("#gridTable").jqGrid({  
        width:930,  
        dataType:'local',         
        colNames:["国家/地区/组织代码","国家/地区/组织名称","操作","国家/地区/组织代码","国家/地区/组织名称","操作"],  
        colModel:[  
                    {name:"code",index:"code",align:'center'},  
                    {name:"name",index:"name",align:'center'},  
                    {name:"operation",index:"operation",align:'center'},  
                    {name:"code1",index:"code1",align:'center'},

                    {name:"operation1",index:"operation1",align:'center'},  
                ],

            records: "records",   
            repeatitems: false   

        },  
        pager:"#gridPager",           
    });  

    var rows = [  
                {"code":"CN","name":"中国","operation":"<span style='color:blue;cursor:pointer;'>应用</span>","code1":"US","name1":"美国","operation1":"<span style='color:blue;cursor:pointer;'>应用</span>"},

                ];  
    for(var i=0;i<rows.length;i++){  
        $("#gridTable").jqGrid('addRowData',i+1,rows[i]);  
    }  



});

或者可以设置data属性(但是没有成功)

$("#grid1").jqgrid(
......
       data:mydata,
　　　　datatype:'local',
.......
);
