The basic javascript console code in Google Chrome for availability is as below

iPhone7availability    Select all
// proper case string prptotype (JScript 5.5+) String.prototype.toProperCase = function() { return this.toLowerCase().replace(/^(.)|\s(.)/g, function($1) { return $1.toUpperCase(); }); } function testip7plus() { var targetProduct = "Plus" var targetCapacity = "256GB" // "32GB", "128GB", "256GB" var targetColor = "Silver" // "Rose Gold" 玫瑰金色, "Gold" 金色, "Sliver" 銀色, "Black" 黑色, "Jet Black" 亮黑色 var FinalSelectedProduct = false; targetCapacity = targetCapacity.toUpperCase() targetColor = targetColor.toProperCase(); var stores_length = $('form#availabilityForm #selectStore option[disabled!=disabled]').length; for(a=0; a<stores_length; a++) { var enabledStore = $('form#availabilityForm #selectStore option[disabled!=disabled]').eq(a).val(); setTimeout(function() { $('form#availabilityForm div.form-element.select-store select').val(enabledStore); $('form#availabilityForm div.form-element.select-store select').change(); },1800) var enabledStoreText = $('form#availabilityForm #selectStore option[disabled!=disabled]').eq(a).text().replace(/^\s+|\s+$/g, ''); var products_length = $('form#availabilityForm #selectSubfamily option[disabled!=disabled]').length; for(p=0; p<products_length; p++) { var enabledProduct = $('div#productSelectionView #selectSubfamily option[disabled!=disabled]').eq(p).val(); var enabledProductText = $('div#productSelectionView #selectSubfamily option[disabled!=disabled]').eq(p).text(); if (~enabledProductText.toLowerCase().indexOf(targetProduct.toLowerCase())) { console.log("Log " + enabledStoreText + " has " + enabledProductText); $('form#availabilityForm div.form-element.select-product select').val(enabledProduct); $('form#availabilityForm div.form-element.select-product select').change(); var unavailableGB = $('div#capacity-row li.unavailable input[value="'+targetCapacity+'"]').length console.log("Log " + enabledStoreText + " checking for " + targetCapacity) if (unavailableGB == 0) { var sizeAva_length = $('div#capacity-row li').length; for(u=0;u<sizeAva_length;u++) { if ($('div#capacity-row li').eq(u).find('div').attr('id') == targetCapacity) { $('div#capacity-row li').eq(u).find("input").click(); break; } } var unavailableColor = $('div#product-row li.unavailable input[data-color="'+targetColor+'"]').length console.log("Log " + enabledStoreText + " checking for " + targetColor) if (unavailableColor == 0) { var colorAva_length = $('div#product-row li').length; for(v=0;v<colorAva_length;v++) { if ($('div#product-row li').eq(v).find('input').attr('data-color') == targetColor) { setTimeout(function() { $('div#product-row li').eq(v).find("input").click(); },800) FinalSelectedProduct = true; break; } } if (FinalSelectedProduct) { console.log("SUCCESS!!!
