구현된 기능: 이동, 일시정지, 재개, 중지
구현되지 않은 기능: 단위 변환 불가, 색상 그라데이션 불가능(개선할 사항이 더 많습니다...)
코드 의 사용방법은 다음과 같습니다.
var $m = $M ("divAnimate");
_("btnAnimate").onclick = function(){
this.disabled =
var that = this; >$m.animate({왼쪽:"300px",top:"100px",너비:"300px", 높이:"200px",opacity:0.3},{duration:5000,easing:Tween.Back.easeInOut}) .delay(200)
.animate({왼쪽:"50px",top:"300px",width:"150px",height:"100px",opacity:0.8},{duration:2000,easing:Tween. Elastic.easeInOut,
callback:function(){
that.disabled = false;
}
})
}
_("btnPause").onclick = function( ){
$ m.pause();
this.disabled = true;
_("btnResume").disabled = false
_("btnResume").disabled = true;
_("btnResume").onclick = function(){
$m.resume();
this.disabled =
_("btnPause").disabled = false;
}
_("btnStop").onclick = function(){
$m.stop()
_("btnAnimate").disabled = false; 🎜>}
