每天学一点flash（79） 输入文本的默认文字

import flash.text.TextField;
import flash.text.TextFieldType;
import flash.events.*;

//定义输入文本
var input:TextField=new TextField();
input.type = TextFieldType.INPUT;
input.text = "请填写名称";
input.border = true;
addChild(input);

//光标事件
input.addEventListener(FocusEvent.FOCUS_IN,onFocusHandler);
input.addEventListener(FocusEvent.FOCUS_OUT,onFocusHandler);
function onFocusHandler(event:FocusEvent):void
{
	if (event.type == FocusEvent.FOCUS_IN)
	{
		input.text = "";
	}
	else
	{
		input.text = "请填写名称";
	}
}
