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 (currentPage currentPage = 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();; } 为什么每次都要建一个颜色对象.事先建好.不是省去很多冗余.而且那个按钮到了第一页和第五页后必须再按一下才会无效..这也算个BUG吧..一同修改过.效果如下: 我觉的这样的效果用时间轴动画实现更为简单. //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); fillColor = new Color(arrowPrev.fill); rgbset(borderColor, 0x999999, fillColor, 0xcccccc); borderColornext = new Color(arrowNext.border); fillColornext = new Color(arrowNext.fill); //上一页按钮 arrowPrev.onRollOver = function() { rgbset(borderColor, 0xff6600, fillColor, 0xFFEBD7); }; arrowPrev.onRollOut = function() { rgbset(borderColor, 0x339966, fillColor, 0xD2F0E1); }; arrowPrev.onRelease = function() { arrowNext.enabled = true; rgbset(borderColornext, 0x339966, fillColornext, 0xD2F0E1); if (currentPage>2) { currentPage = parseInt(currentPage)-1; } else { currentPage = parseInt(currentPage)-1; this.enabled = false; rgbset(borderColor, 0x999999, fillColor, 0xcccccc); } }; //下一页按钮 arrowNext.onRollOver = function() { rgbset(borderColornext, 0xff6600, fillColornext, 0xFFEBD7); }; arrowNext.onRollOut = function() { rgbset(borderColornext, 0x339966, fillColornext, 0xD2F0E1); }; arrowNext.onRelease = function() { arrowPrev.enabled = true; rgbset(borderColor, 0x339966, fillColor, 0xD2F0E1); if (currentPage currentPage = parseInt(currentPage)+1; } else { currentPage = parseInt(currentPage)+1; this.enabled = false; rgbset(borderColornext, 0x999999, fillColornext, 0xcccccc); } }; //拖动场景 drag.onMouseDown = function() { if (this.hitTest(_xmouse, _ymouse, true)) { startDrag(_root); } }; drag.onMouseUp = function() { stopDrag(); }; function rgbset(rgbobj1, rgb1, rgbobj2, rgb2) { rgbobj1.setRGB(rgb1); rgbobj2.setRGB(rgb2); }
