1、返回數(shù)組中的第一個元素

var letters:Array = new Array("a", "b", "c", "d", "e", "f"); var someLetters:Array = letters.slice(0,1); trace(someLetters);//a

2、返回數(shù)組中最后一個元素

var letters:Array = new Array("a", "b", "c", "d", "e", "f"); var someLetters:Array = letters.slice(-1); trace(someLetters);//f

3、返回數(shù)組中前兩個元素

var letters:Array = new Array("a", "b", "c", "d", "e", "f"); var someLetters:Array = letters.slice(0,2); trace(someLetters);//a,b

4、返回數(shù)組中倒數(shù)第二個元素

var letters:Array = new Array("a", "b", "c", "d", "e", "f"); var someLetters:Array = letters.slice(-2,-1); trace(someLetters);//e

5、返回數(shù)組所有元素

var letters:Array = new Array("a", "b", "c", "d", "e", "f"); var someLetters:Array = letters.slice(); trace(someLetters);//a,b,c,d,e,f

6、總結(jié)，第一個參數(shù)是起始索引，如果第二個參數(shù)不寫，就返回起始索引到數(shù)組最后所有的元素。參數(shù)不填，默認(rèn)返回數(shù)組所有元素，也就是數(shù)組的淺復(fù)制。起始索引是負(fù)值是表示從后面開始。
