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();
};
}
