How can we retrieve value on main.mxml from other .mxml?
- by Roshan
main.mxml
[Bindable]
private var _dp:ArrayCollection = new ArrayCollection([
{day:"Monday", dailyTill:7792.43},
{day:"Tuesday", dailyTill:8544.875},
{day:"Wednesday", dailyTill:6891.432},
{day:"Thursday", dailyTill:10438.1},
{day:"Friday", dailyTill:8395.222},
{day:"Saturday", dailyTill:5467.00},
{day:"Sunday", dailyTill:10001.5}
]);
public var hx:String ;
public function init():void
{
//parameters is passed to it from flashVars
//values are either amount or order
hx = Application.application.parameters.tab;
}
]]>
</mx:Script>
<mx:LineChart
id="myLC"
dataProvider="{_dp}"
showDataTips="true"
dataTipRenderer="com.Amount"
>
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="day" />
</mx:horizontalAxis>
<mx:series>
<mx:LineSeries xField="day" yField="dailyTill">
</mx:LineSeries>
</mx:series>
</mx:LineChart>
com/Amount.mxml
[Bindable]
private var _dayText:String;
[Bindable]
private var _dollarText:String;
override public function set data(value:Object):void{
//Alert.show(Application.application.parameters.tab);
//we know to expect a HitData object from a chart, so let's cast it as such
//so that there aren't any nasty runtime surprises
var hd:HitData = value as HitData;
//Any HitData object carries a reference to the ChartItem that created it.
//This is where we need to know exactly what kind of Chartitem we're dealing with.
//Why? Because a pie chart isn't going to have an xValue and a yValue, but things
//like bar charts, column charts and, in our case, line charts will.
var item:LineSeriesItem = hd.chartItem as LineSeriesItem;
//the xValue and yValue are returned as Objects. Let's cast them as strings, so
//that we can display them in the Label fields.
_dayText = String(item.xValue);
var hx : String = String(item.yValue)
_dollarText = hx.replace("$"," ");
}//end set data
]]>
</mx:Script>
QUES : Amount.mxml is used as dataTipRenderer for line chart. Now, I need to obtain the value assigned to variable "hx" in main.mxml from "com/Amount.mxml".Any help would be greatly appreciated?
