[Flash]*a typing effect

yesterday very night,a guy call me on the QQ and ask how to make this effect,but it's such a long time since I use Flash last time,so I anwser that maybe frame by frames will fit u,But when I was on bed,i have a comand of myself to try it out,at least in mind,so today I'mhere programming now ,and blows are my codes:

import mx.controls.Label;

import mx.controls.Button;

import mx.controls.TextInput;

createClassObject(TextInput,"input",4{text:""});

createClassObject(Label,"lab",3{text:" "});

createClassObject(Button,"btn",2,{label:"Oops"});

btn.onPress = function() {

var n = 0;

var s:String = input.text;

var ID = setInterval(showText, 1000);

function showText() {

n++;

lab.text = s.substr(0, n-1);

trace("ok"+s.substr(0, n-1));

if (n>=s.length+1) {

clearInterval(ID);

}

updateAfterEvent();

}

};
