                {
                    field: ‘OPERATE‘, title: ‘操作‘, width: 100, align: "center", formatter: btnDetailed
                }
        ]],

   });

// 详细按扭
function btnDetailed(value, rowData, rowIndex) {
    if (typeof rowData.ENTITY_NO == "string") {
        return ‘<input type="button" value="详细" onclick="clickDetailedEntity( \‘‘ + $.trim(rowData.ENTITY_NO) + ‘\‘);" class="easyui-linkbutton" iconCls="icon-edit" plain="true" style="width:50px;height:20px;" />‘;
    }
}

另：用<button>详细</button>来添加按钮时，当点击按钮时，页面会刷新

用<input  type="button" value="详细"/> 点击按钮时不会刷新页面
