[RESOLVED] Javascript Arrays :embarrassed

[dougal85]

I cant figure how out how to do this! It's doing my head in.

in PHP i would do...

$arrayname[] = "something";

I don't know how to add something to javascript without defining an index.

Thanks.

arrayname[arrayname.length]="something"; or something like that.

[JPnyc]

var arrayname= new Array('bucket1','bucket2');

That's 1 way. There are a few ways

Weedpacket's method is how I usually deal with this situation. Basically, you're defining the next index - ".length" tells you how many items are in the array (e.g. 2 if we take JPnyc's code from above). Since arrays start at index #0, the last valid index of the array is length - 1 (or 1, as in JPnyc's example array). So, if you simply take length instead of subtracting one, you'd get the next unused ID.
