// ==UserScript== // @name Auto Parts Price Rounder (X4.37 / X9.37) + Copy Button + Auto Search // @namespace tweeks.io // @version 9.0 // @description Rounds displayed auto part prices so the last digit before the decimal is 4 or 9 and cents are always .37; minimum 35.37. Adds a copy button without the dollar sign, auto-submits pasted searches, and supports minipartsdirect.com, oempartsonline.com, partsnow sites, and other catalogs. // @author Tweeks // @match *://*/* // @grant TW_notifications // ==/UserScript== (function () { 'use strict'; // --------------------------------------------------------------------------- // Catalog definitions: each entry describes how to find and update prices // on a specific family of sites. // --------------------------------------------------------------------------- var CATALOGS = [ // --- *partsnow.com family (kiapartsnow, hyundaipartsnow, genesispartsnow, etc.) --- { name: 'partsnow', test: function () { return /partsnow\.com/i.test(location.hostname); }, wrapSelector: '.pn-price-wrap', priceSelector: 'span.price-section-price', saveSelector: '.price-section-save', msrpSelector: 'span.price-section-retail span', observeSelector: '.pn-base-r-wrap, main, body', observeTriggerClasses: ['pn-price-wrap', 'price-section-price'], extractPrice: function (el) { return parsePrice(el.textContent.trim()); }, setPrice: function (el, value) { var updated = false; el.childNodes.forEach(function (node) { if (node.nodeType === Node.TEXT_NODE) { var t = node.textContent; if (/\d+\.\d+/.test(t)) { node.textContent = t.replace(/\d+\.\d+/, formatPrice(value)); updated = true; } } }); if (!updated) { el.textContent = '$' + formatPrice(value); } } }, // --- mazdapartsnow / hondapartsnow / toyotapartsnow / subarupartsnow --- // These sister sites share the same React app structure as *partsnow.com // and are already covered by the entry above.
