效果描述：在动画运行框里面输入一串文本，然后点提交按钮，你就看到文本移动效果了！

代码如下：

stop();

mc.setMask(mask_mc);

var v:Number = 5;//移动速度

var i:Number = 0;

var num:Number;

_btn.onPress = function() {

mc.t_txt.text = input_txt.text;

runMove();

};

_btn.onRelease = function() {

input_txt.text = "";

};

function runMove() {

onEnterFrame = function(){

if (mc._x>212) {

mc._x -= v;

}else{

delete onEnterFrame;

num=setInterval(funstop,1000);

};

updateAfterEvent();

};

};

function funstop() {

i++;

if (i>=4) {//中间停留时间

clearInterval(num);

run_left();

}

}

function run_left() {

onEnterFrame = function () {

mc._x -= v;

if (mc._x<=94) {

delete onEnterFrame;

mc._x = 319;

}

updateAfterEvent();

};

}
