本文实例讲述了JS实现二维数组元素的排列组合运算。分享给大家供大家参考，具体如下：

var arrays = [["a0","a1","a2","a3"],["b0","b1","b2","b3"],["c0","c1","c2","c3"],["d0","d1","d2","d3"]];
var array = getArrayByArrays(arrays);
document.getElementById('value').value = array+"....."+array.length;
function getArrayByArrays(arrays)
{
var arr = [""];
for(var i = 0;i<arrays.length;i++)
{
arr = getValuesByArray(arr,arrays[i]);
}
return arr;
}
function getValuesByArray(arr1,arr2)
{
var arr = [];
for(var i=0;i<arr1.length;i++)
{
var v1 = arr1[i];
for(var j=0;j<arr2.length;j++)
{
var v2 = arr2[j];
var value = v1+v2;
arr.push(value);
};
};
return arr;
}
</script>

运行结果：
希望本文所述对大家JavaScript程序设计有所帮助。
