Question

我正在尝试制作六个数组，所以我已经手动创建了它们。我知道有一种方法可以让这整个混乱更短，但它让我的思绪下滑。

var variant_1:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

var variant_2:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

var variant_3:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

var variant_4:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

var variant_5:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

var variant_6:Array = new Array
                    (rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), rp.getNum(), 
                     "", "",  "", "",  "", "", "", "", "", "", "", "");

注意： getNum（）是一个函数，它为我提供1到90之间的随机数字范围，然后我将它们分配给动态创建的表。

注意2 ：数组中的空值是表格中的空单元格，因为在9x3的表格中我需要15个数字和12个空格。

注意3 ：是的，这是宾果游戏。

谢谢。

Answer 1

您可以使用for循环，例如

for(var i:int=0; i<10; i++) {
  trace(i);       
}

对于您要执行的操作，可以将其包装在返回新数组的函数中

function createArray(){
   var a = [];//new array

   for(var i:int=0; i<??; i++) {
      //some conditions
      if(i < ??)  {
         //push to array
      }  
      else {
         //push to array
      }  
   } 

  return a;
}


var myNewArray:Array = createArray();

请查看http://www.adobe.com/devnet/actionscript/learning/as3-fundamentals/loops.html有关循环的详细介绍。

Answer 2

var variants = createVariants(6, 15, 12);

//使用您的变体： // variants [0] [0]与您的variant_1 [0]

相同

function createVariants(numVariants : int, numPrefilled : int, numEmpty : int) : Array{
  var variants : Array = [];
  for(var i : int = 0;i<numVariants;i++){
    var variant : Array = [];
    for(var j : int = 0;j<numPrefilled ;j++){
      variant.push(rp.getNum());
    }
    for(var j : int = 0;j<numEmpty ;j++){
      variant.push("");
    }
    variants.push(variant);
  }
  return variants;
}

Answer 3

基于Paul的答案，您还可以使用二维数组来存储每个数组，这样可以使用循环来创建所需数量的变量（成本会增加必须维护的复杂性）一个2d数组）。

使用2d数组可能是：

function createArrayVarient(){
    var result:Array = new Array();
    var counter:int;

    // 15 as there are 15 numbers added first
    for(counter = 0; counter < 15; counter++){
        result.push(rp.getNum());
    }

    // 12 for the number of "" added
    for(counter = 0; counter < 12; counter++){
        result.push("");
    }
    return result;
}

var arrayVarients:Array = new Array();

// 6 as you have 6 array variants in your sample
for(var counter = 0; counter < 6; counter++){
    arrayVarients.push(createArrayVarient());
}

然后如果您之前没有使用过2d数组，要访问“arrayVarients”中的每个数组变量，它将会出现：

arrayVarients[0] // the first array variant
arrayVarients[1] // the second array variant
arrayVarients[2] // the third array variant
...etc

访问数组变体中的每个值，它将（使用2个索引）：

arrayVarients[0][0] // the first value in the first variant array
arrayVarients[2][7] // the eight value in the third variant array

Answer 4

我想这就是你想要的

var iVariantCount:int = 6;//number of variants
var arrVariants:Array = new Array();//this will hold your variants array (variant_1,variant_2,etc)
var iVariantLength:int = 27;//total no fo elements in a variant array
var iRandomNumCount:int = 15;//no of random numbers in a variant array

for (var i:int = 0;  i<iVariantCount ; i++) 
{
    var arrVariant:Array = new Array();
    for (var j:int = 0;  j < iVariantCount ; j++) 
    {
        if (i < iRandomNumCount)
        {
            arrVariant.push(rp.getNum());
        }
        else
        {
            arrVariant.push("");
        }
        arrVariants.push(arrVariant);
    }   
}

//Check the result
for (i = 0;  i<arrVariants.length ; i++) 
{
    trace("Variant_" + i + ": " + arrVariants[i]);
}

试试这个并告诉我它是否适合你。
