 $('#rightMenu').menu('show', { left: e.pageX, top: e.pageY }); e.preventDefault();
}
	<th data-options="field:'code'">Code</th>
	<th data-options="field:'name'">Name</th>
	<th data-options="field:'price'">Price</th>
</table>

<div id="rightMenu" class="easyui-menu" style="width:100px;display: none">
    <div iconCls="icon-xls" οnclick="exportData()">导出数据</div>
</div>

<script src="datagrid-export.js" charset="utf-8"></script>
<script>
  // 导出轨迹点数据
  function exportData(){
    var tbl = $("#tbl");
    var items = tbl.datagrid("getRows");
    tbl.datagrid("toExcel", {
    filename: "xxxx数据.xls",
    rows: items,
    worksheet: "Sheet"
  });
</script>
```
