easyui中，searchbox和datagrid一起使用时发现的一个问题

<div id="shaixuanqu" style="padding: 5px;">

//这里是一个普通的searchbox控价，由于我的是js输出控件，所以不太方便贴代码

    </div>



<table id="dg" data-options="toolbar:'#shaixuanqu'"></table>

<script>

        $("#dg").datagrid({

            method: "GET",

            width: "100%",

            height: frmHeight + "px",

            fitColumns: true,

            showFooter: true,

            striped: true,

            pagination: true,

            pageSize: 21,

            pageList: [10, 21, 50, 100],

            loadFilter: pagerFilter,

            onDblClickCell: function (index, field, value) {                

                   //一些业务代码                

            },



            frozenColumns: [[

                { field: "编码", title: "编码", sortable: true, width: "100px" },

                { field: "条形码", title: "条形码" },                

            ]],

            columns: [[                

                { field: "中文称呼", title: "中文称呼", editor: "textbox", width: "150px" },

                { field: "英文称呼", title: "英文称呼", editor: "textbox", width: "150px" }

            ]],

           

        });

    </script>
