1、设计思路
(1)新建一个DataGrid,在其中最后一列加入三个按钮:新增、修改和删除;
(2)点击新增按钮,可以将表格新增一行;
(3)单击“修改”按钮,可以修改表格中该行的一些属性;
(4)单击“删除”按钮,会将表格中该行删除。
2、实现步骤
(1)新建一个应用程序,DataGrid.mxml
DataGrid.mxml:
<?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <s:layout> <s:BasicLayout/> </s:layout> <fx:Declarations> <!-- 将非可视元素(例如服务、值对象)放在此处 --> </fx:Declarations> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; [Bindable] //表格数据源绑定 private var grid:ArrayCollection = new ArrayCollection([ {number:"2014010101",name:"张三",sex:"男",age:"19"}, {number:"2014010102",name:"李思",sex:"女",age:"20"}, {number:"2014010103",name:"蔡华",sex:"男",age:"21"}, {number:"2014010104",name:"牛耳",sex:"女",age:"22"}, {number:"2014010105",name:"兆司",sex:"男",age:"18"}, {number:"2014010106",name:"胡柳",sex:"女",age:"19"}, {number:"2014010107",name:"刘斯",sex:"男",age:"20"}, {number:"2014010108",name:"孙阳",sex:"女",age:"22"}, {number:"2014010109",name:"郑武",sex:"男",age:"21"}, {number:"2014010110",name:"王雪",sex:"女",age:"20"}, {number:"2014010111",name:"胡柳",sex:"女",age:"19"}, {number:"2014010112",name:"刘斯",sex:"男",age:"20"}, {number:"2014010113",name:"孙阳",sex:"女",age:"22"}, {number:"2014010114",name:"郑武",sex:"男",age:"21"}, {number:"2014010115",name:"王雪",sex:"女",age:"20"} ]); ]]> </fx:Script> <mx:VBox width="100%" height="100%" paddingBottom="100" paddingLeft="100" paddingRight="100" paddingTop="100"> <mx:DataGrid id="dataGrid" dataProvider="{grid}" rowCount="{grid.length+1}" width="100%" textAlign="center"> <mx:columns> <mx:DataGridColumn headerText="学号" dataField="number" id="stuNumber"/> <mx:DataGridColumn headerText="姓名" dataField="name"/> <mx:DataGridColumn headerText="性别" dataField="sex"/> <mx:DataGridColumn headerText="年龄" dataField="age"/> <mx:DataGridColumn headerText="操作"> <mx:itemRenderer> <fx:Component> <mx:HBox width="100%" paddingLeft="40"> <fx:Script> <![CDATA[ import mx.managers.PopUpManager; /*添加按钮事件函数*/ protected function addHandler(event:MouseEvent):void { var childWindow:ChildWindow = ChildWindow(PopUpManager.createPopUp(this,ChildWindow,true)); var point:Point = new Point(100,100); childWindow.x = point.x + 400; childWindow.y = point.y + 50; } /*修改按钮事件函数*/ protected function updateHandler(event:MouseEvent):void { var updateWindow:UpdateWindow = UpdateWindow(PopUpManager.createPopUp(this,UpdateWindow,true)); var point:Point = new Point(100,100); updateWindow.x = point.x + 400; updateWindow.y = point.y + 50; updateWindow.stuNo = event.currentTarget.selectedItem.content; } ]]> </fx:Script> <mx:LinkButton label="新增" click="addHandler(event)"/> <s:Label width="10"/> <mx:LinkButton label="修改" click="updateHandler(event)"/> <s:Label width="10"/> <mx:LinkButton label="删除"/> </mx:HBox> </fx:Component> </mx:itemRenderer> </mx:DataGridColumn> </mx:columns> </mx:DataGrid> </mx:VBox> </s:Application>
(2)新建一个新增窗口组件,ChildWindow.mxml
ChildWindow.mxml:
<?xml version="1.0" encoding="utf-8"?> <s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" close="closeHandler(event)" title="新增窗口"> <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ import mx.events.CloseEvent; import mx.managers.PopUpManager; /*关闭按钮函数*/ protected function closeHandler(event:CloseEvent):void { PopUpManager.removePopUp(this); } /*取消按钮函数*/ protected function cancelHandler(event:MouseEvent):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <!-- 将非可视元素(例如服务、值对象)放在此处 --> </fx:Declarations> <mx:VBox width="100%" height="100%" horizontalAlign="center"> <mx:Form borderStyle="solid" borderColor="#CCCCCC" width="100%"> <mx:FormHeading label="新增界面" fontSize="14"/> <mx:FormItem label="学号:"> <s:TextInput id="stuNo" width="200"/> </mx:FormItem> <mx:FormItem label="姓名:"> <s:TextInput id="stuName" width="200"/> </mx:FormItem> <mx:FormItem label="性别:"> <s:TextInput id="stuSex" width="200"/> </mx:FormItem> <mx:FormItem label="年龄:"> <s:TextInput id="stuAge" width="200"/> </mx:FormItem> </mx:Form> <mx:HBox width="100%" height="25"> <s:Label width="60"/> <s:Button label="新增"/> <s:Label width="48"/> <s:Button label="取消" click="cancelHandler(event)"/> </mx:HBox> </mx:VBox> </s:TitleWindow>
(3)新建一个修改界面组件,UpdateWindow.mxml
UpdateWindow.mxml:
<?xml version="1.0" encoding="utf-8"?> <s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300" close="closeHandler(event)" title="修改窗口"> <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ import mx.events.CloseEvent; import mx.managers.PopUpManager; /*关闭按钮函数*/ protected function closeHandler(event:CloseEvent):void { PopUpManager.removePopUp(this); } /*取消按钮函数*/ protected function cancelHandler(event:MouseEvent):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <!-- 将非可视元素(例如服务、值对象)放在此处 --> </fx:Declarations> <mx:VBox width="100%" height="100%" horizontalAlign="center"> <mx:Form borderStyle="solid" borderColor="#CCCCCC" width="100%"> <mx:FormHeading label="修改界面" fontSize="14"/> <mx:FormItem label="学号:"> <s:TextInput id="stuNo" width="200"/> </mx:FormItem> <mx:FormItem label="姓名:"> <s:TextInput id="stuName" width="200"/> </mx:FormItem> <mx:FormItem label="性别:"> <s:TextInput id="stuSex" width="200"/> </mx:FormItem> <mx:FormItem label="年龄:"> <s:TextInput id="stuAge" width="200"/> </mx:FormItem> </mx:Form> <mx:HBox width="100%" height="25"> <s:Label width="60"/> <s:Button label="修改"/> <s:Label width="48"/> <s:Button label="取消" click="cancelHandler(event)"/> </mx:HBox> </mx:VBox> </s:TitleWindow>
