如何将数组推向数组？ （二维数组javascript codeigniter）

Question

对不起，我是一个JavaScript初学者。 我的数据有问题。 我希望有人能给我解决方案（与js的文档或在这里回答）。 我有阵列

var array1 = ["you","they","them","he","she","it"]; 
var array2 = ["we","us","me","I"]; 

和我有一个数组来保存阵列

var data = [][]; //I don't know how to write. 

如何保存在数据ARRAY1和数组2？ 以及如何打印该数据？ 谢谢。

Answer 1

试试这个。

var array1 = ["you","they","them","he","she","it"]; 
 
var array2 = ["we","us","me","I"]; 
 

 
var mergedArray = []; 
 
mergedArray.push(array1); 
 
mergedArray.push(array2); 
 
console.log(mergedArray); //To access the merged array 
 
console.log(mergedArray[0]); //To access first array 
 
console.log(mergedArray[0][0]); //To access element inside first array

Answer 2

通过创建一个数组

var arr = []; 

刚开始时，只是把你的其他阵列它

arr.push(["you","they","them","he","she","it"]); 
arr.push(["we","us","me","I"]); 

您可以检索单个项目，像这样

var youVar = arr[0][0]; // has value "you"
