如何为两个数组的内容创建所有可能的组合? [英] How can I create every combination possible for the contents of two arrays?

问题描述

我有两个数组:

var array1 = ["A", "B", "C"];
var array2 = ["1", "2", "3"];

如何设置另一个数组以包含上述所有组合，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])
     }
}
