Basic Questions About Arrays

Copy linkTweet thisAlerts:
Feb 16.2004

Hi everybody.

I have a question about the arrays:

Is there a function or a way to know the lenght or the dimmension of an array??? I really need to know.

I supose that I can use a variable to control the number of elements as I add them to it, but I’d prefer to use something like array.lenght or lenght(array), or like in VBScript:
UBound(array).

If someone knows… please help me!!! I’m quite new in JavaScripts.

@gil_davisFeb 16.2004 — All arrays have a length attribute free of charge.
var myAry = new Array("one","two","three","four");
alert(myAry.length); // should say 4
As to dimension, arrays are one dimension. However that does not prevent you from making each element an array also. It is not the same as BASIC where you have to dimension an array first.
