Why can't I add an element with an attribute to an array?

Question

JavaScript

I'm tormented by adding elements with a certain attribute to the array, although I seem to be doing everything right. I'm using the autocomlect library, can it interfere? Tell me where is the mistake?

here is the code:

var masiive = []	
masiive.push(($('<li>').attr("data-context-key"));
alert(masiive)

Here is the code demonstrating the problem: jsfiddle.net/t52ka/107

Answer 1

masiive.push(($('<li>').attr("data-context-key"));
the first parenthesis is redundant.
