[AS3]删除数组一段连续的元素返回被删除的元素数组

var arr:Array = ["a","b","c","d","e","f","g"];  
arr.splice(删除点的索引,要删除的个数,新元素1,新元素2);  
arr.splice(2,3,"o","p","q");//从索引为2开始，删除3个元素，并插入3个新元素"o","p","q" 
arr.splice(-2,3,"o","p","q");//从倒数为2的索引开始，删除3个元素，并插入3个新元素"o","p","q" 
arr.splice(2,3);//单纯的删除从索引2开始的3个元素(不插入)  
arr.splice(2);//单纯的删除从索引2开始的所有元素(不插入)  
arr.splice(2,0,"x","y","z");//在索引2的后面插入3个新元素(不删除)
