If I have for example this array-variable:
var arr=[
[1,2,3]
[4,5,6]
]
How can I insert something in that array, for example like this:
arr=[
[1,2,3]
[4,5,6]
[7,8,9]
]
I tried arr=[arr,[7,8,9]] but then the [] are building up.
How to do this?
arr.push([7,8,9]);
That should do the trick. If you want to insert:
arr.splice(offset,0,thing_to_insert);
Use push:
arr.push([7,8,9]);
Try this:
arr.push([7,8,9]);
push() is a standard array method
Try this:
var arr=[
[1,2,3]
[4,5,6]
] ;
arr.push([7,8,9]);
Array.prototype.push adds elements to the end of an array.
var arr=[
[1,2,3]
[4,5,6]
];
arr.push([7,8,9]);
Array.prototype.splice lets you add elements to the array at any index you desire:
var arr=[
[1,2,3]
[4,5,6]
];
arr.splice(arr.length, 0, [7,8,9]);
You could use push?
I'm not sure if this would work:
arr.push([7,8,9]);
but I'm sure this would work:
arr.push(7);
arr.push(8);
arr.push(9);
arr after your last code would look like this: [[1,2,3],[4,5,6],7,8,9] ... which is not correct.
