AS3 将数组添加到另一个数组

Question

我的问题示例。

 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

这将执行您正在查找的内容，还允许您将多行数据添加到 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

如 cmets 中所述，您可以使用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]);

当然，这看起来很乱。我想知道您为什么无缘无故地将数组存储在其他数组中。
