I created this Chrome extension: https://chrome.google.com/webstore/detail/backpacktf-price-checker/aneicgekdeglaaiechdnaeiefgfdfpno?hl=en

The purpose of this extension is to supply an easy-to-use backpack.tf price checker directly in Chrome. It also features price tagging directly on items on tf2outpost.com.

I would really like to bring this functionality to dispenser.tf, but it would be very difficult unless information about the item is included in the item's tile. TF2Outpost does this using the data and search attributes:

If something like this could be added to dispenser.tf, I could bring backpack.tf price tags here!

Added appid, contextid, defindex and quality in the html for each item.

Each item got an attribute 'itemattr', the values in order are appid, contextid, defindex and quality.

e.g. itemattr="440,2,5046,6" -> Team Fortress (440,2), Team Spirit (5046), Unique (6)

This attribute only apply to items of Valve games. Steam Gifts has no defindex (we identify each Steam Gift with icon URL), so this attribute cannot uniquely identify Steam Gifts.

It looks like only some items are getting the itemattr attribute.

Example without itemattr:
