AngularJS Shopping Cart Example
AngularJS
A framework for web-based applications is AngularJS. It enables you to utilise HTML as one's template language and increase HTML's syntax to represent the constituents of your application concisely and unambiguously. Data binding as well as dependency injection in AngularJS allow one to write a lot less code than you would normally. And because everything takes place inside the browser, every server architecture may work well with it.
It is common to use: to address the ambiguity between dynamic applications as well as static documents.
- A library is a group of functions that may be used while creating web applications. As it deems appropriate, your code is in control and makes calls into the library. Consider jQuery.
- Frameworks are specific web application implementations in which your code handles the specifics. Whenever the framework requires anything app-specific, it goes inside your code. The framework is in control. For instance, Durandal, Ember, etc.
Complete client-side solution:
It takes several different components to develop the user/client side of a webpage, and AngularJS is only one of them. It takes care of and organises all of the DOM and AJAX glue code you manually wrote in the past. Because of this, AngularJS has strong opinions on how to create applications. Although it has an opinion, it also works to ensure that it is merely a beginning point that can be readily altered. The following details are included with AngularJS out of the bucket:
- Data-binding, fundamental formatting instructions, form validating, navigation, deep connecting, reusable components, and dependency injection are all part of a comprehensive set that you can use to construct CRUD apps.
- Testability story -Unit testing, end-to-end testing and test harnesses are examples of testability.
What is a Shopping Cart?
On the website of an online store, a shopping cart is just a part of a software module that makes it easier to buy a particular item or service. It arranges the delivery of the customer's payment details to the retailer, payment gateway, and other entities in addition to accepting the customer's transaction.
Why Shopping Carts are Crucial
The finest shopping cart technology is crucial for your website since it bridges the gap between browsing and purchasing.
Those who are newly entering the market are probably not acquainted with the idea. Most individuals have probably bought something online several times in their life, particularly those who work in the e-commerce sector. However, the majority of customers do not completely appreciate the use and potential of shopping carts. Usually, a cart has three features in common:
- It keeps track of product data.
- It serves as a portal for managing orders, catalogues, and customers.
- It displays product data, category information, and site information for users.
Here is another angle to consider the situation from The physical shopping carts we use at the retail outlet are comparable to the virtual ones, but the virtual one serves many more purposes. Additionally, information is sent to the bank through the shelves, the structure, the clearing sign, the accounting software, and sometimes the credit card reader.
Example of Shopping Cart using AngularJS
Designing a Cart Page
To create this page, we'll use Bootstrap. We'll include our Bootstrap-designed pages inside our AngularJS app as soon as it's finished. We won't go too deep into Bootstrap intricacies while creating the page, but we will concentrate on a few key elements.
Make an HTML page with the name index.html.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Bootstrap Shop Cart</title>
<!-- Bootstrap core CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>
<style>
body {
padding-top: 50px;
}
#divTotal{
background-colour: green;
}
.affix{
right: 0px;
}
.affix-top{
right: 0px;
position: fixed;
}
</style>
</head>
<body>
<div class="container">
</div>
</body>
</html>
Make a .row div within the. container div.
<div class="row">
</div>
We'll need two columns on the index.html page. The first column will contain a pricing list of the products, and the second column will show the Total div. Now let us start by making the two columns.
<div class="col-xs-7 col-md-8 col-sm-8 col-lg-8">
</div>
<div class="col-xs-5 col-md-4 col-sm-4 col-lg-4">
</div>
Now let's add very few products and choices to the first column.
<div class=" panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">Panel title</h3>
</div>
<div class="panel-body">
<div class="radio">
<label>
<input type="radio" name="optradio">Option 1</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optradio">Option 1</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optradio">Option 1</label>
</div>
</div>
</div>
To add a few more things, repeat the aforementioned HTML code a few times in the initial column. Add the below HTML script to the second column to display the total cost of the chosen products.
<div class=" panel panel-primary">
<div id="divTotal" class="panel-heading">
<h3 class="panel-title">Total</h3>
</div>
<div class="panel-body">
<h2>Rs. 100</h2>
</div>
</div>
<div class="text-center">
<a href="#/checkout" class="btnbtn-danger">Checkout <span class="glyphiconglyphicon-shopping-cart" aria-hidden="true"></span>
</a>
</div>
Navigate to index.html after saving the modifications. It should resemble:
It seems fine. The Total div has to be corrected, however, so that it won't shift whenever the browser is scrolled. We're going to use the Affix Bootstrap Js module to address it.
