jQuery EasyUI的DataGrid 数据行上右键问题

如下图：

我想查看单行数据（如ID为20）的右键上获取该行的值，代码：

JavaScript code

 

<script type="text/javascript">
$(function(){
    $('#test').datagrid({
        title:'DataGrid数据列表',
        iconCls:'icon-grid',
        fit:true,
        collapsible:true,
        closable:true,
        nowrap: false,
        animate:true,
        url: '<%=rootPath%>data/getJobs',
        idField:'id',
        pagination: true,
        pageSize:20,
        pageList: [10,20,30,40,50,100],
        onRowContextMenu: onRowContextMenu, //右键。[表头(tab)右键onHeaderContextMenu,树形(tree)右键onContextMenu]
        rownumbers: true,
        singleSelect: true,
        columns:[[
            {title:'',field:'ck',120,checkbox:true},
            {field:'id',title:'岗位ID',80},
            {field:'job_name',title:'岗位名称',80},
            {field:'dat',title:'入职日期',80,align:'right'},
            {field:'work_address',title:'工作地点',80},
            {field:'salary',title:'薪资',80,align:'right'},
            {field:'status',title:'状态',60},
        ]],
        onLoadSuccess: function() {
            delete $(this).datagrid('options').queryParams['id'];
        }
        
    });
});
</script>

右键菜单：

XML/HTML code

<div id="mm" class="easyui-menu" style="120px;">
    <div onClick="view()" data-options="iconCls:'icon-search'">查看</div>
    <div onClick="add()" data-options="iconCls:'icon-add'">新增</div>
    <div onClick="edit()" data-options="iconCls:'icon-edit'">编辑</div>
    <div onClick="del()" data-options="iconCls:'icon-remove'">删除</div>
    <div class="menu-sep"></div>
    <div onClick="print()" data-options="iconCls:'icon-print'">打印</div>
    <div onClick="reload()" data-options="iconCls:'icon-reload'">刷新</div>
</div>

javascript:

//添加右击菜单内容
function onRowContextMenu(e, rowIndex, rowData){
   e.preventDefault();
    var selected=$("#test").datagrid('getRows'); //获取所有行集合对象
     var idValue = selected[rowIndex].id;
     $(this).datagrid('selectRecord', idValue);  //通过获取到的id的值做参数选中一行
    $('#mm').menu('show', {
        left:e.pageX,
        top:e.pageY
    });       
}
//查看详细
function view(){
/***
就是这里获取单行数据方法???? 
treeGrid上倒是很好实现:
  var node = $('#datagrid').treegrid('getSelected');
  if(node){
    ........
  }
***/
}
