Small JS userscript to highlight items on steam market with min price lower than specified. Kinda shitty though.

steamAuctioneer.js

// ==UserScript==
// @name        Steam market highlighter
// @namespace   hj
// @description Highlights low prices
// @include     http://steamcommunity.com/market/*
// @version     1
// @grant       none
// ==/UserScript==

function addJQuery(callback) {
	var script = document.createElement("script");
	script.setAttribute("src", "//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js");
	script.addEventListener('load', function() {
		var script = document.createElement("script");
		script.textContent = "window.jQ=jQuery.noConflict(true);(" + callback.toString() + ")();";
		document.body.appendChild(script);
	}, false);
	document.body.appendChild(script);
}

function main() {
    // Highlight prices beyound
    var treshold = 31.0
    
	jQ("span:contains('Starting at')").each(function(i,s){
		if (parseFloat(s.textContent.split(":")[1].replace(",",".").match(/\d+[\.]\d+/)) < treshold){
			jQ(s).parent().parent().css("background-color","rgb(130, 150, 130)").css("color","black")
		}
	})
	jQ("#market_buynow_dialog_accept_ssa_container").css("width","100%").css("background-color", "green").css("position","relative")
	jQ("#market_buynow_dialog_accept_ssa_label").css("position","absolute").css("top", "0").css("bottom", "0").css("left","0").css("right","0")
}
