ExtJs表格控件Grid
下面介绍三种ExtJs中最常见的表格控件:GridPanel,EditorGridPanel,PropertyGrid.
1.创建普通的Grid表格
/** 创建普通的Grid表格 */function createGridPanel(){ var myData = [//以数组的形式定义数据 ['3m Co',71.72,0.02,0.03,'9/1 12:00am','www.baidu.com'], ['Alcoa Inc',29.01,0.42,1.47,'10/1 12:00am','www.163.com'], ['Boeing Co.',75.43,0.53,0.71,'9/2 12:00am','www.sina.com.cn'], ['Hewlett-Packard Co.',36.53,-0.03,-0.08,'9/1 12:00am','www.iteye.com'], ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'8/30 12:00am','www.oracle.com']];var myStore = new Ext.data.ArrayStore({//定义用于存放数据的store,并且为每个字段取名data: myData,//把数据绑定到storefields: [//为每列取名,并且设置数据类型 {name: 'name'}, {name: 'price', type: 'float'}, {name: 'change', type: 'float'}, {name: 'pctChange', type: 'float'}, {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}, 'url']}) ;var myGrid = new Ext.grid.GridPanel({//定义列表 store: myStore,//把定义好的store绑定到此列表 columns: [//根据在store中定义的列名,把列数据绑定到相应的列表头 {header: '姓名', width: 200, sortable: true, dataIndex: 'name'},//dataIndex:store中定义的fieldname. {header: '价格', renderer: Ext.util.Format.usMoney, dataIndex: 'price'},//renderer: Ext.util.Format.usMoney,显示美元的货币符号 {header: '改变', renderer:function(v){ if(v<=0){ return "<font color='red'>"+v+"</font>" ; }else{ return v ; } }, dataIndex: 'change'}, {header: '改变百分比', dataIndex: 'pctChange'}, { header: '最后改变时间', width: 135, dataIndex: 'lastChange', xtype: 'datecolumn', format: 'Y-m-d'//显示日期型变量的格式 }, {header: '网址', renderer: function(v){ return v.link(v) ;//渲染成超链接形式 }, dataIndex: 'url'}]}) ;new Ext.Viewport({layout:'fit',items:myGrid}) ;//充满整个body显示列表}2.创建可编辑的Grid表格
/** 创建可编辑的Grid表格 注意:EditorGrid与Grid的区别在于,在要想设置成可编辑的列中定义如下属性editor: Ext.form.TextField(DateField) */function createEditorGridPanel(){ var myData = [//以数组的形式定义数据 ['3m Co',71.72,0.02,0.03,new Date(),'www.baidu.com'], ['Alcoa Inc',29.01,0.42,1.47,new Date(),'www.163.com'], ['Boeing Co.',75.43,0.53,0.71,new Date(),'www.sina.com.cn'], ['Hewlett-Packard Co.',36.53,-0.03,-0.08,new Date(),'www.iteye.com'], ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,new Date(),'www.oracle.com']];var myStore = new Ext.data.ArrayStore({//定义用于存放数据的store,并且为每个字段取名data: myData,//把数据绑定到storefields: [//为每列取名,并且设置数据类型 {name: 'name'}, {name: 'price', type: 'float'}, {name: 'change', type: 'float'}, {name: 'pctChange', type: 'float'}, {name: 'lastChange', type: 'date'}, 'url']}) ;var myGrid = new Ext.grid.EditorGridPanel({//定义列表 store: myStore,//把定义好的store绑定到此列表 columns: [//根据在store中定义的列名,把列数据绑定到相应的列表头 {header: '姓名', width: 200, sortable: true,editor: Ext.form.TextField, dataIndex: 'name'},//dataIndex:store中定义的fieldname. {header: '价格', renderer: Ext.util.Format.usMoney, dataIndex: 'price'},//renderer: Ext.util.Format.usMoney,显示美元的货币符号 {header: '改变', renderer:function(v){ if(v<=0){ return "<font color='red'>"+v+"</font>" ; }else{ return v ; } }, dataIndex: 'change'}, {header: '改变百分比', dataIndex: 'pctChange'}, { header: '最后改变时间', width: 135, dataIndex: 'lastChange',editor: Ext.form.DateField,//此字段可以编辑 xtype: 'datecolumn', format: 'Y-m-d H:i:s'//显示日期型变量的格式 }, {header: '网址', renderer: function(v){ return v.link(v) ;//渲染成超链接形式 }, dataIndex: 'url'}]}) ;new Ext.Viewport({layout:'fit',items:myGrid}) ;//充满整个body显示列表}3.创建Property(Key-value)的Grid表格
/** 创建Property(Key-value)的Grid表格 下在source中定义的是name及对应的value(默认值),在页面的列表中可以对value进行编辑修改 */function createPropertyGridPanel(){ var grid = new Ext.grid.PropertyGrid({ title: 'Properties Grid', autoHeight: true, width: 300, source: { "(name)": "My Object", "Created": new Date(), "Available": false, "Version": .01, "Description": "A test object" }});new Ext.Viewport({layout:'fit',items:grid}) ;//充满整个body显示列表}?4.载入相应的列表
/** 载入相应的列表 *///Ext.onReady(createGridPanel);//Ext.onReady(createEditorGridPanel);Ext.onReady(createPropertyGridPanel);?
