jqGrid在编辑行时获取行数据方式以及自定义 select 的用法

<script type="text/javascript">
    function myelem (value,options){
         //创建 select 元素
        var el = document.createElement("select");
        if(value){  //编辑时
            //获取被编辑列id
            var id = $("#jqGrid").jqGrid('getGridParam','selrow');
            //根据 id 获取行数据对象
            var rowDatas = $("#jqGrid").jqGrid('getRowData',id);
            //获取物品 id
            var goodsId = rowDatas["goodsId"];
            //获取物品名称
            var goodsName = rowDatas['goodsName'];
            el.options[0] = new Option(goodsName, goodsId);
        }else{  //新增时
            el.options[0] = new Option("金币", 1);
        }
        return el;
    }

    function myValue(elem,operation, value){
        if(operation == 'get'){
            return $(elem).val();
        }else if(operation == 'set'){
            $('select',elem).val(value);
        }
    }

//获取物品列表填充物品下拉列表数据
function getGoodsList(){
        var goodsType = $("#goodsType").val();
        var url = "";
        if(goodsType <= 2){
            url = "xxx";
        }
        if(goodsType == 3){
            url = "xxx";
        }

        $.post(url,{"type":goodsType},function(data,textStatus){
            var options = "";
            if(data.length > 0){
                for(var i=0; i < data.length; i++){
                    options += "<option value=\"" +data[i].id+ "\">" + data[i].zhName + "</option>";
                }
                $("#goodsId").html(options);
            }
        },"json");
    }
