1.首先看效果 2.需要一个合计插件GridSummary.js GridSummary 插件，下载后将后缀名该为 js 3.页面需要引用的文件 1 <link rel="stylesheet" type="text/css" href="include/ext-3.4.0/resources/css/ext-all.css" />
2 <link rel="stylesheet" type="text/css" href="include/ext-3.4.0/ux/css/ux-all.css" />
3 <script type="text/javascript" src="include/ext-3.4.0/adapter/ext/ext-base.js"></script>
4 <script type="text/javascript" src="include/ext-3.4.0/ext-all.js"></script>
5 <script type="text/javascript" src="include/ext-3.4.0/ux/ux-all.js"></script>
6 <script type="text/javascript" src="include/ext-3.4.0/locale/ext-lang-zh_CN.js"></script>
7 <script type="text/javascript" src="include/ext-3.4.0/ux/GridSummary.js"></script> <!-- 合计插件 -->
8 <script type="text/javascript" src="demo.js"></script> <!-- 示例js -->
4.Grid代码 var url = "RequestAction/AT/Req_CT_SHIPMENTS.aspx?Action=GetDetailAll&S_SHIPMENTS_M_GUID=" + guid;
//复选框
var sm = new Ext.grid.CheckboxSelectionModel();
var textFileldVehicle = new Ext.form.TextField
({
allowBlank: false,
blankText: "请输入车号",
maxLength: 50
});
var numField = new Ext.form.NumberField({
allowNegative: false,
allowDecimals: true,
allowFormat: true,
decimalPrecision: 2,
allowBlank: false,
blankText: '金额必须大于零'
});
//字段集合
var fields =
[
{ name: 'S_VEHICLE_NUMBER' },
{ name: 'N_QUANTITY' },
{ name: 'N_FREIGHT' },
{ name: 'S_GUID' },
{ name: 'S_SHIPMENTS_M_GUID' }
];
var proxy = new Ext.data.HttpProxy({ url: url });
//数据读取器
var reader = new Ext.data.JsonReader({
totalProperty: "totalPorperty", //数据总条数
root: "rows", //将要显示数据的数组
id: "S_GUID", //每一行数据的唯一记录
fields: fields
});
//列集合 其中 summaryType: 'sum' 为求和
var cm = new Ext.grid.ColumnModel
({ columns: [sm,
new Ext.grid.RowNumberer({ header: 'NO', width: 30, align: 'center' }),
{ header: '车号', dataIndex: 'S_VEHICLE_NUMBER', editor: textFileldVehicle, summaryRenderer: function (v, params, data) { return '合计'; } },
{ header: '重量', dataIndex: 'N_QUANTITY', summaryType: 'sum', renderer: formatNumberDefault, align: 'right', editor: numField },
{ header: '运费', dataIndex: 'N_FREIGHT', summaryType: 'sum', renderer: formatNumberDefault, align: 'right', editor: numField}
]
});
//如果全部列都可排序否则单个设置
cm.defaultSortable = false;
//创建一个store
var shipmentsDetailstore = new Ext.data.Store({
proxy: proxy,
reader: reader,
autoDestroy: true,
autoLoad: { params: { start: 0, limit: pageSize} }
});
//插入行按钮
var btn_Insert = new Ext.Button({ text: '插入行', iconCls: 'insert', handler: function () {
//定义一个recode对象
var initValue = createShipmentDetailRow();
grid.stopEditing();
var maxRowIndex = grid.getStore().getCount();
grid.getStore().insert(maxRowIndex, initValue); //在第一个位置插入
grid.view.refresh();
grid.getSelectionModel().selectLastRow();
grid.getView().focusRow(maxRowIndex); //焦点标记行
grid.startEditing(maxRowIndex, 2); //单元格转换成编辑状态
}
});
//删除行按钮
var btn_Remove = new Ext.Button({ text: '删除行', iconCls: 'delete', handler: function () {
grid.stopEditing();
var rows = grid.getSelectionModel().getSelections();
if (rows == undefined || rows.length == 0) {
setShipmentStatusBarText('error', '请选择需要删除的行！');
return; //判断记录集是否为空，为空返回
}
grid.getStore().remove(rows);
grid.view.refresh();
}
});
//工具栏
var tbar = new Ext.Toolbar({
cls: 'top-toolbar',
items: [btn_Insert, '-', btn_Remove]
});
var summary = new Ext.ux.grid.GridSummary();
//创建GRID
var grid = new Ext.grid.EditorGridPanel
({
id: 'ShipmentsDetailGirdPanel',
deferredRender: false,
enableColumnHide: false,
enableHdMenu: false,
columnLines: true,
enableColumnMove: false,
store: shipmentsDetailstore,
sm: sm,
cm: cm,
loadMask: true,
//自适应宽度 参数为列数
// autoExpandColumn: 4,
//超过长度带自动滚动条
autoScroll: true,
border: false,
nocache: false,
timeout: 10,
clicksToEdit: 1,
scripts: true,
loadMask: { msg: '正在加载数据，请稍侯……' },
tbar: tbar,
view: new Ext.ux.grid.BufferView({
rowHeight: 25,
scrollDelay: true,
forceFit: true,
deferEmptyText: true,
emptyText: "无数据"
}),
plugins: summary
}); 5.此时会看到合计行字体偏小 添加样式 .x-grid3-summary-row .x-grid3-cell-inner {
FONT: 12.5px tahoma,arial,helvetica,sans-serif
} 6.此示例Ext版本为 3.4.0
