	<mx:Script>
		<![CDATA[
			import mx.controls.Alert;
			import mx.controls.CheckBox;
			
			private function onClickHandler(event:Event):void 
			{
				var idx:int;
				var len:int = arr.length;
				for (idx=0; idx<len; idx++) {
					if (textInput[idx].text == "" ) {
						status.text = "required field.";
						stage.focus = textInput[idx];
						break;
					}
				}
				status.text = "";
				Alert.show("submit data");
			}
			
		]]>
