So I'm creating a web worker:

var arrayit = function(obj) {

  return Array.prototype.slice.call(obj);

};

work = arrayit(images);

console.log(work);

//work = images.push.apply( images, array );

// Method : load+scroll

var worker = new Worker('jail_worker.js');

worker.postMessage(work)

worker.onmessage = function(event) {

  console.log(Worker said: + event.data);

};

Here's what images is:

$.jail.initialStack = this;

// Store the selector into 'triggerEl' data for the images selected

this.data('triggerEl', (options.selector) ? $(options.selector) : $window);

var images = this;

I think my problem has something to do with this:

How can I get around this? as you can see, I tried slicing the host object into a real array, but that didn't work.

Here's a link to the file I'm hacking on:

UPDATE--------------------------------------------------

This is what I had to do based on the accepted answer from @davin:

var arrayit = function(obj) {

  return Array.prototype.slice.call(obj);

};

imgArray = arrayit(images);

work = _.map(images, function(i){ return i.attributes[0].ownerElement.outerHTML; });



var worker = new Worker('jail_worker.js');

worker.postMessage(work)

worker.onmessage = function(event) {

  console.log(Worker said: + event.data);

};

NOTE: I used underscore.js to assure compatibility.
