Question

I declared a array variable els = []; in which I want to store jquery elments which are created at some point within certain events:

els[file.id] = $('<li></li>');
$('body').append(els[file.id]);

file.id is a unique id generated by the plupload script which I’m using (the event is from it)

But it doesnt work, the array is always empty…

Answer 1

Arrays can only have sequential, numeric keys. You can’t choose arbitrary keys. To use arbitrary key-value pairs, use an object:

var els = {};

With that said, the code you’ve written should still work (even though els.length would be 0) – perhaps this isn’t a complete code sample?
