TextInput

[Booma Devi]

Hi,

Can any one please help me how to get the key value from the map in flex..?

I have used the property file in server side which contains the value as K=1000 B=100000. In flex side, I have red the key and value pair..

What I need this, when I type the string say 1K in the textInput, i want to retrieve the K value (1000) from the flex side...


Code is below:

<?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" creationComplete="serv.getCurrValue()">
	<fx:Declarations>
		<!-- Place non-visual elements (e.g., services, value objects) here -->
		<mx:RemoteObject id="serv" destination="currencyDestination" fault="faultHandler(event)" result="resultHandler(event)"/>
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[
			
			import mx.collections.ArrayCollection;
			import mx.controls.Alert;
			import mx.rpc.events.FaultEvent;
			import mx.rpc.events.ResultEvent;   
				
			[Bindable]
			public var persons:Object;   
			[Bindable]
			public var currValue:Number;
			[Bindable]
			public var currKey:String;
			
			public function faultHandler(event:FaultEvent):void  
			{   
				Alert.show(event.fault.faultDetail,"Error");   
			}   
			
			public function resultHandler(event:ResultEvent):void  
			{   
				var persons:Object=event.result as Object;
				
				for(var key:String in persons)
				{
					var currKey:String=key;             
					var currValue:Object=persons[key];
										
				}
			}
			
			public function ti_keyUpHandler(event:KeyboardEvent):void
			{
				
				    if(event.charCode==75)
					{
		
					} }
			]]>
	</fx:Script>
	
	<s:TextInput id="ti" keyUp="ti_keyUpHandler(event)"/>
</s:Application>

var persons:Object=event.result as Object;

for(var key:String in persons)
{
var currKey:String=key;
var currValue:Object=persons[key];

}

This looks a little strange. "persons" is a single object and its being used in a foreach loop(which doesnt make sense)..."key" in the first iteration would probably be the string representation of persons reference variable and not the 1000 that you want.

Hi Praveen,

Could you please help me to solve this....

I have one textInput which allows only 10 chars... If I enter the text as 1T in spark text input then it will become 1,000.00 (here length is 8)..

My requirement is I dont want to allow the char K again in textInput because if I enter the character K then it will exceeds the maximum character... How to restrict the character K in textinput.. so that we cant
exceed the max char limit...


Thanks in Advance....
