使用JavaScript合并多维数组中的两个数组

Question

How can I merge two arrays ?

I tried this :

var data = {};
var array1 = [1.79 , 2.33 , 3.1];
var array2 = [2];
var data = array1.concat(array2);

it displays [1.79 , 2.33 , 3.1 , 2]

but I want to display the result this way : [1.79 , 2.33 , 3.1][2]

Answer 1

 var array1 = [1.79 , 2.33 , 3.1]; var array2 = [2]; var data = [array1,array2]; console.log(JSON.stringify(data)); 

Answer 2

try like this

 var array1 = [1.79 , 2.33 , 3.1]; var array2 = [2]; var data = [array1,array2]; console.log(data); 

Answer 3

You can either use push or concat and merge multiple arrays, Below are 2 methods provided to perform the merging of arrays:

 //Method 1 var array1 = [1.79 , 2.33 , 3.1]; var array2 = [2]; array1.push.apply(array1, array2) console.log(array1); //Method 2 var array1 = [1.79 , 2.33 , 3.1]; var array2 = [2]; var multipleArrays = [array1, array2]; var flatArray = [].concat.apply([], multipleArrays); console.log(flatArray); 

Answer 4

You need to push the two arrays into a new, empty array like below.

var data = [];
var array1 = [1.79 , 2.33 , 3.1];
var array2 = [2];
data.push(array1, array2);
