我怎样才能为两个数组的内容创建可能的组合？ [英] How can I create every combination possible for the contents of two arrays?

问题描述

我有两个数组：

I have two arrays:

var array1=["A","B","C"];

var array2=["1","2","3"];

如何设置另一个数组来包含上述的每个组合，以便：

How can I set another array to contain every combination of the above, so that:

var combos=["A1","A2","A3","B1","B2","B3","C1","C2","C3"];

推荐答案

这种形式的循环

combos = [] //or combos = new Array(2);

for(var i = 0; i < array1.length; i++)
{
     for(var j = 0; j < array2.length; j++)
     {
        //you would access the element of the array as array1[i] and array2[j]
        //create and array with as many elements as the number of arrays you are to combine
        //add them in
        //you could have as many dimensions as you need
        combos.push(array1[i] + array2[j])
     }
}
