在一些特定应用中,我们需要用到按钮的Disabled状态.下面我们就来制作一个这样的效果.
1.首先,在场景中新建一个MC(影片剪辑MovieClip),在此MC中绘制一个图形,把线条和填充颜色分别转换为MC,如图1:

(图1);
2.完成后拖到场景中,复制一个,并调整方向,分别取实例名为”arrowPrev””arrowNext”,如图2:

(图2)
3.在场景中绘制一个动态文本,命名变量名为”currentPage”,用于显示当前页数;
4.界面工作完毕,下面新建一图层,命名为AS,按F9打开动作面板,输入/复制下面的代码:

//初始化页面总数
pageNum = 5;
//初始化按钮
arrowPrev.enabled = false;
arrowNext.enabled = true;
borderColor = new Color(arrowPrev.border);
borderColor.setRGB("0x999999");
fillColor = new Color(arrowPrev.fill);
fillColor.setRGB("0xcccccc");
//上一页按钮
arrowPrev.onRollOver = function() {
borderColor = new Color(this.border);
borderColor.setRGB("0xff6600");
fillColor = new Color(this.fill);
fillColor.setRGB("0xFFEBD7");
};
arrowPrev.onRollOut = function() {
borderColor = new Color(this.border);
borderColor.setRGB("0x339966");
fillColor = new Color(this.fill);
fillColor.setRGB("0xD2F0E1");
};
arrowPrev.onRelease = function() {
arrowNext.enabled = true;
borderColor = new Color(arrowNext.border);
borderColor.setRGB("0x339966");
fillColor = new Color(arrowNext.fill);
fillColor.setRGB("0xD2F0E1");
if (currentPage>1) {
currentPage = parseInt(currentPage)-1;
} else {
this.enabled = false;
borderColor = new Color(this.border);
borderColor.setRGB("0x999999");
fillColor = new Color(this.fill);
fillColor.setRGB("0xcccccc");
}
};
//下一页按钮
arrowNext.onRollOver = function() {
borderColor = new Color(this.border);
borderColor.setRGB("0xff6600");
fillColor = new Color(this.fill);
fillColor.setRGB("0xFFEBD7");
};
arrowNext.onRollOut = function() {
borderColor = new Color(this.border);
borderColor.setRGB("0x339966");
fillColor = new Color(this.fill);
fillColor.setRGB("0xD2F0E1");
};
arrowNext.onRelease = function() {
arrowPrev.enabled = true;
borderColor = new Color(arrowPrev.border);
borderColor.setRGB("0x339966");
fillColor = new Color(arrowPrev.fill);
fillColor.setRGB("0xD2F0E1");
if (currentPagecurrentPage = parseInt(currentPage)+1;
} else {
this.enabled = false;
borderColor = new Color(this.border);
borderColor.setRGB("0x999999");
fillColor = new Color(this.fill);
fillColor.setRGB("0xcccccc");
}
};
//拖动场景
drag.onMouseDown=function(){
if(this.hitTest(_xmouse,_ymouse,true)) startDrag(_root,false);
}
drag.onMouseUp=function(){
stopDrag();;
}下是最终生成的效果和源文件:
