I recently decided to buy a house and to fund the down payment I would sell off my Prosper notes. Prosper has a trading platform that works well enough but from the standard interface you can only sell 10 notes at a time. 50 if you do it a more complicated way, but neither is all that helpful when trying to sell 1000 loans.

Keep in mind that this hack is not very robust. If you want to stop selling notes automatically when you go to the not trading platform’s sell page you need to disable the extension. If you want to quit in the middle, you will need to disable it manually or close the tab. It currently only does the one thing I wanted it to do. Sell ALL my notes.

The following should work in greasemonkey for firefox, or in chrome as an add-on. It assumes you want to sell at 100% of value in a auction format. But with a little work you could make this work for fixed price sales and other percentages.

Using jQuery mobile for the client site today I came across an interesting problem.  The client had an existing HTML privacy policy document with a bunch of anchor tags linking to hashes within the page.  Since jQuery mobile uses the hash for it’s ajax loading the #top, #whatWeCollect and so on links would of course trigger a new (non-existant) page to load.

To get around this limitation in jQuery Mobile I wrote a little script:

$('.ui-page').live('pagebeforeshow',function()
{
	$('.retroHashes').find('a[href^="#"]').unbind('click').click(function(e)
	{
		e.stopPropagation();
		e.preventDefault();

		var $target = $(this).parents('.ui-page').find($(this).attr('href')).eq(0);
		if($target.length == 1)
		{
			$.mobile.silentScroll($target.offset().top);
		}
		return;
	});
});

Essentially, what is going on here is that when a “page” is loaded by jQuery Mobile, I am looking for a wrapper element with the class “retroHashes”. Inside this element is the old [ugly] code I got from my client.

The I look for all the anchor tags where the href begins with the hash.  If it does I unbind anything that might have been attached to click by other methods.  Not very nice and you might not want to do that step but in my case I was fragging all other behaviors on these links.

I bind new functionality to the click.  stopPropagation() prevents jQuery Mobile from doing it’s ajax load.

The rest is finding the target.  In my case the client was setting the the id of the target element and not the name, so I can actually just use the href attribute of the link as the selector.

I check to make sure that I found a target, and scroll to the offset within the document.

There you have it.  A quick hash link hack for jQuery Mobile.  If people like it I may expand this example to more use cases.
