split is not a function on array

Question

I have just started programming with javascript. I am trying to work with arrays and I don't understand why I am getting a split is not a function error, when I try to split the content of the array like in the following code.

var addressArray=[[]];
/*
some code to pass values to the addressArray 

*/

var values=addressArray[i].split(/ ,+/);

the error is occuring where I am spliting

There's no .split() function for arrays. There is a String .split() however. It's hard to know what it is you want to do without actually seeing the stuff in your array. — Pointy

in the array there phrase like: 1 housenumber street city, 2 hause number street city — akaAlso

Incidentally, that regex matches "exactly one space followed by one or more commas", which seems an odd thing to look for. But maybe it makes sense in your context. — IMSoP

You cannot split an array itself - split() is used to split a string into an array. I suspect you're attempting to split a string that is within an array, in which case you should be careful to index the string correctly. Looking at your declaration of addressArray:

var addressArray=[[]];

You seem to have nested arrays, in which case you will need to use two indices to refer to a string within an array, which is itself within addressArray; for example, addressArray[i][j].split(/ ,+/).
