titlewindow弹出 传递参数 和 barchart点击获取数据

点击barchart弹出相对应的数据，用到了titlewindow和datagrid

flex代码：

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" minWidth="955" minHeight="600" initialize="chart()"> <mx:Script> <!--[CDATA[ import mx.charts.CategoryAxis; import mx.charts.events.ChartItemEvent; import mx.charts.series.items.BarSeriesItem; import mx.charts.series.items.ColumnSeriesItem; import mx.collections.ArrayCollection; import mx.controls.Alert; import mx.managers.PopUpManager; import mx.rpc.events.ResultEvent; import mx.utils.ArrayUtil; [Bindable] public var getxml:XML=new XML; [Bindable] public var getxml1:XML=new XML; private function result1(event:ResultEvent):void { getxml=XML(event.result); } private function result2(event:ResultEvent):void { getxml1=XML(event.result); } private function chart():void{ var sql1:String="select * from stu1"; wbs.student(sql1); } private var point1:Point = new Point(); private function click1(event:ChartItemEvent):void{ var chart:BarSeriesItem=event.hitData.chartItem as BarSeriesItem; var sql:String="select * from stu where age between left('"+chart.item.年龄+"',2) and right('"+chart.item.年龄+"',2)"; wbs.conn(sql); var detail:titlewindow=new titlewindow; detail.xmldata=getxml1.Table; detail.x=1; detail.y=21; PopUpManager.addPopUp(detail,this,true); } ]]--> </mx:Script> <mx:WebService id="wbs" wsdl="http://localhost:3645/WebSite7/Service.asmx?WSDL" > <mx:operation name="conn" result="result2(event)"/> <mx:operation result="result1(event)" name="student"/> </mx:WebService> <mx:Panel x="51" y="21" width="562" height="342" layout="absolute" fontSize="12"> <mx:BarChart itemClick="click1(event)" x="130.5" y="33" id="barchart1" width="281" height="235" dataProvider="{getxml.Table}"> <mx:verticalAxis> <mx:CategoryAxis id="cate" categoryField="年龄"/> </mx:verticalAxis> <mx:series> <mx:BarSeries id="bar1" displayName="男" xField="男" yField="年龄"/> <mx:BarSeries id="bar2" displayName="女" xField="女" yField="年龄"/> </mx:series> </mx:BarChart> <mx:Legend dataProvider="{barchart1}" x="22" y="80"/> <mx:Label id="label1" width="100"/> </mx:Panel> </mx:Application>

titlewindow代码：

?

<?xml version="1.0" encoding="utf-8"?> <!-- Main application to demonstrate TitleWindow layout container. --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <!--[CDATA[ import mx.managers.PopUpManager; import mx.containers.TitleWindow; import flash.geom.Point; private var point1:Point = new Point(); private function showWindow():void { var login:SimpleTitleWindowExample=SimpleTitleWindowExample(PopUpManager.createPopUp( this,SimpleTitleWindowExample,true)); point1.x=myButton.x; point1.y=myButton.y; point1=myButton.localToGlobal(point1); login.x=point1.x+25; login.y=point1.y+25; login.loginName=returnedName; } ]]--> </mx:Script> <mx:Panel title="TitleWindow Container Example" height="75%" width="75%" paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10"> <mx:Button id="myButton" label="Click to open the TitleWindow container" click="showWindow();"/> <mx:Text id="returnedName" text="" width="100%"/> </mx:Panel> </mx:Application>

webservic和前几天写的那个是一样的，连接数据库然后把数据给dataset?，再给flex。这里有一个主页面和titlewindow之间传递参数的问题，先实例化titlewindow然后再把参数传给它：

?
???var detail:titlewindow=new titlewindow;
????
???detail.xmldata=getxml1.Table;
????
???detail.x=1;
???detail.y=21;
????
???PopUpManager.addPopUp(detail,true);

?

也可以在titlewindow页面[Bindable]一个，比如叫 data，然后在主页面和上面一样，detail.data=要传递的参数值

就可以了

?

弹出窗口也可以采用这种方式：

var detail:titlewindow=new titlewindow(PopUpManager.createPopUp(this,detail,true);

?

下面的代码，是获取点击的item的数据的方法：

?var chart:BarSeriesItem=event.hitData.chartItem as BarSeriesItem;
???var sql:String="select * from stu where age between left('"+chart.item.年龄+"',2)";
???wbs.conn(sql);

?

还有一个问题没有解决，就是titlewindow里的datagrid的数据源获取，总是比我点击晚一步，也就是我点击的时候要的数据，是上一次点击该出来的。。不知道该怎么解决。。
