count arrays in js

[Ginso]

hello,
when i send arrays to my js file like in the getAllDatas or with notifyAllPlayers, the objects that js gets are not really arrays.
How can i get the number of entries there?

Just use array_values in your php code when sending arrays so that js get them as array and not object.

Or use Object.keys(yourCollection).length

If you send php associative array, you get an object in js.

You can get values of object properties as array with

Code: Select all

	Object.values(gamedatas.something)

Now you have array and you can do with him anything you will do with arrays:

Code: Select all

	let something = Object.values(gamedatas.something);
	console.length(something.length);
	something.forEach(item => console.log(item));

More info about Object.values is here: https://developer.mozilla.org/en/docs/W ... ect/values

Or use Object.keys(yourCollection).length

Sure but then what the point of sending associative array if you just use the values ?
