1.extjs,如何将前面的操作放到grid后面,详情如图所示

var grid = Ext.create('Ext.grid.Panel', { store: store, stateful: true, collapsible: true, multiSelect: true, stateId: 'stateGrid', columns: [ { text : 'Company', flex : 1, sortable : false, dataIndex: 'company' }, { text : 'Price', width : 75, sortable : true, renderer : 'usMoney', dataIndex: 'price' }, { text : 'Change', width : 75, sortable : true, renderer : change, dataIndex: 'change' }, { text : '% Change', width : 75, sortable : true, renderer : pctChange, dataIndex: 'pctChange' }, { text : 'Last Updated', width : 85, sortable : true, renderer : Ext.util.Format.dateRenderer('m/d/Y'), dataIndex: 'lastChange' }, { menuDisabled: true, sortable: false, xtype: 'actioncolumn', width: 50, items: [{ icon : '../shared/icons/fam/delete.gif', // Use a URL in the icon config tooltip: 'Sell stock', handler: function(grid, rowIndex, colIndex) { var rec = store.getAt(rowIndex); alert("Sell " + rec.get('company')); } }, { getClass: function(v, meta, rec) { // Or return a class from a function if (rec.get('change') < 0) { this.items[1].tooltip = 'Hold stock'; return 'alert-col'; } else { this.items[1].tooltip = 'Buy stock'; return 'buy-col'; } }, handler: function(grid, rowIndex, colIndex) { var rec = store.getAt(rowIndex); alert((rec.get('change') < 0 ? "Hold " : "Buy ") + rec.get('company')); } }] } ], height: 350, width: 600, title: 'Array Grid', renderTo: 'grid-example', viewConfig: { stripeRows: true, enableTextSelection: true } }）；类似这样可以实现在一个列中有多个按钮图标。

2.如何在ext的window窗口里放置grid?

首先定义好grid

var grid = new Ext.grid.GridPanel({

。。.

});

然后定义window

var win = new Ext.Window({

title : 'TEST',

width : 500,

closeAction : 'hide',

items : [grid]

});

然后在你需要显示window的地方加上win.show（)；即可
