AS3将阵列添加到另一个阵列

Question

我的问题的示例。

var array_1:Array = new Array(); 
array_1[0] = [2,4,6,8]; 

var array_2:array = new Array(); 
array_2[0] = [10,12,14,16]; 
array_2[1] = [18,20,22,24]; 

// and the out come I want it to be is this 
trace(array_1[0]) // 2,4,6,8,10,12,14,16,20,22,24 

// I did try array_1[0] += array_2[0] but it didn't work currently 

任何建议都会很棒。

Answer 1

这将执行你在找什么，也可以让你多行数据添加到array_1或array_2

var array_1:Array = new Array(); 
array_1[0] = [2,4,6,8]; 

var array_2:Array = new Array(); 
array_2[0] = [10,12,14,16]; 
array_2[1] = [18,20,22,24]; 

var combinedArray:Array = new Array(); 
for(var i:int = 0; i < array_1.length; i++) { 
    combinedArray = combinedArray.concat(array_1[i]); 
} 
for(i = 0; i < array_2.length; i++) { 
    combinedArray = combinedArray.concat(array_2[i]); 
} 

trace(combinedArray); 

Answer 2

正如评论所说，你可以使用concat方法：

var array_1:Array = new Array(); 
array_1[0] = [2,4,6,8]; 

var array_2:array = new Array(); 
array_2[0] = [10,12,14,16]; 
array_2[1] = [18,20,22,24]; 

array_1[0] = array_1[0].concat(array_2[0]).concat(array_2[1]); 

这当然是很凌乱看。我想知道为什么你没有明显的理由将数组存储在其他数组中。
