as+xml.txt

一个简单的flash滚动条

前两个星期抽时间看了看一直很感兴趣却没时间研究的XML类和绘图API
觉得也没之前想象的那么神秘：）

用了三个晚自习的时间用AS1.0写了这个纯AS+XML的滚动条，算做练习吧。
请高手多多指教！

下面是所有的AS代码：

//%%%%%%%%%%%%MC类自定义方法%%%%%%%%%%%%//
//——————绘图方法————//
//三角型方法
MovieClip.prototype.sanjiaoxing = function(zuobiao1, zuobiao2, zuobiao3, bangzhi, yanse, toumingdu) {
    this.lineStyle(bangzhi, yanse, toumingdu);
    this.moveTo(zuobiao1.x, zuobiao1.y);
    this.lineTo(zuobiao2.x, zuobiao2.y);
    this.lineTo(zuobiao3.x, zuobiao3.y);
    this.lineTo(zuobiao1.x, zuobiao1.y);
};
//宽高矩形法，根据初始点坐标和宽与高确定矩形。x，y为初始点坐标，kuan和gao为矩形的宽和高。
MovieClip.prototype.changkuanjuxing = function(x, y, kuan, gao, bangzhi, yanse, toumingdu) {
    this.lineStyle(bangzhi, yanse, toumingdu);
    this.moveTo(x, y);
    this.lineTo(x+kuan, y);
    this.lineTo(x+kuan, y+gao);
    this.lineTo(x, y+gao);
    this.lineTo(x, y);
};
//中心点矩形法，根据中心点的坐标和宽与高确定矩形。x，y为中心点坐标，kuan，gao为矩形的长和宽。
MovieClip.prototype.zhongxinjuxing = function(x, y, kuan, gao, bangzhi, yanse, toumingdu) {
    this.lineStyle(bangzhi, yanse, toumingdu);

    this.lineTo(x-kuan/2, y-gao/2);
    this.lineTo(x-kuan/2, y+gao/2);
};
//————定位方法————//
MovieClip.prototype.dingwei = function(x, y) {
    this._x = x;
    this._y = y;
};
//————上色方法————//
//定义一个获取颜色值，并把它转化成16进制的函数   
//获取颜色值的后六位，使此方法可以同时满足“#FFFFFF”和“0xFFFFFF”两种格式的颜色值

    var yansezhi = yansezhi.substr(-6, 6);
    return parseInt(yansezhi, 16);

    this.setRGB(jinzhizhuanhuan(yansezhi));
};
