Flex 产生随机数、随机颜色

 //创建一个x~y之间的随机数（不包含y值），Math.round(Math.random() * (y - x)) + x;  
      
//0-5之间的随机数，不包含5  
var index: Number = Math.round(Math.random() * 5);  
var colors: Array = ["#FF00FF", "#0000FF", "#000000", "#008000", "#800000"];  
color = colors[index];                 

//15-25之间的随机数，不包含25  
var index: Number = Math.round(Math.random() * (25 - 15)) + 15;  

随机16进制颜色：Alert.show((Math.random()* 0xffffff).toString(16));  
color = "#" + (Math.random()* 0xffffff).toString(16);
