Shopping Online automation

Question

I want to create script to online shopping automation for this site.

link to product eg: http://www.lazada.com.my/remax-otg-micro-to-usb-adapter-pendrive-mouse-reader-ra-otg-forandroid-gold-10498828.html?mp=1&boost=1

with reference from this question (Choosing and activating the right controls on an AJAX-driven site). But as a person who got zero knowledge about JavaScript language, im here seeking help from those who able to help and share their knowledge here. Thank you in advance.

This is what i got so far, and i dont know how to combine them to make it 1 complete script.

Step 1. Add to cart

jQuery(function(){
jQuery('#AddToCart').click();

Step 2. Checkout

$(document).ready(function() {
$(".btn-checkout col submit_btn mtssel-cart-checkout-button").click(function() {
    _gaq.push(['_trackPageview', $(this).attr('https://www.lazada.com.my/checkout/step/index/')]);
});

Step 3. Login Prelogin

Step 4. Shipping

jQuery(function(){
jQuery('.shipping_btn').click();
});

Step 5. Payment(There's few payment option to be choose from tabs. I'll use paypall.)

$(document).ready(function() {
$("#tabs-Paypal").tabs();
$('#action').click(function() {
    var selected = $( "#tabs-Paypal" ).tabs({ active: # });
});

(not working)

Step 6. Place order

Question: So is it possible to do all the step with 1 click only using javascript? And how to combined all those to make 1 complete script?
