snack.wrap on non-existent element returns length of 1

[jenshedqvist]

When I run snack.wrap on an element that doesn't exist in the DOM I expect it to return an object with length of zero (0). Alternatively "undefined". This is needed to test if an element exists.

This is what I get when I run snack.wrap on an non-existent element today:

0 []

id 16

length 1

addClass function()

attach function()

data function()

delegate function()

detach function()

each function()

fire function()

removeClass function()

I've changed line 154 (in my version of snack.js) from

wrapper.length = l 

to

wrapper.length = (l == 1 && nodes[0].nodeName === undefined) ? 0 : l

Haven't tested rigorously but it works for me so far.
