Description

Learn to create a useful web tool that calculates and converts results for your users. In this project, you'll help webpage visitors calculate their energy savings from switching to efficient LED and CFL light bulbs. Chris Converse walks through each step in the process: building the main HTML page, creating the form elements, styling the layout with CSS, and performing calculations on the input using JavaScript and AngularJS's data binding elements. Chris also helps you adjust the layout to display better on small screens and mobile devices.

Using these lessons, and the free exercise files, you can build any kind of calculation tool for your clients, from shipping cost to mortgage payment calculators.

Introduction
3 Lectures 02:59

This goal of this course is to teach you to create a calculation too for your web site. We’ll be using three key pieces of information in order calculate and compare different outcomes.

Preview 01:16

We’ll be creating a calculation tool in this course that will allow users to compare energy usage and costs between different types of light bulbs.

Preview 00:43

The exercise files contains ready-to-use SVG graphics, and HTML, CSS files, a copy of AngularJS, as well as a copy of full final project. (Find the exercise files in Section 2, Lecture 4 "Hooking in CSS and AngularJS")

Preparing the Page Structure with HTML
4 Lectures 12:11

We'll begin by hooking our CSS and AngularJS files into our HTML file. (Find the Exercise Files in this lecture)

Hooking in CSS and AngularJS
02:43

To begin our layout, we’ll create the HTML structure necessary for the structure and content of our calculation tool.

Add main HTML structure
02:01

Using HTML5 section elements, we’ll create an area to display the wattage and costs for each bulb.

Add in labels, wattage and cost
02:55

In order to give users the ability to choose and input values, we’ll add the form controls within an HTML form elements.

Adding the form elements

Creating the Layout with CSS
8 Lectures 32:19

Using CSS, we’ll style the top section, allowing room for background graphics.

Styling the light bulb sections
04:08

Now we’ll make use of the SVG graphics by assigning them into multi-colored backgrounds.

Preview 03:54

Using CSS text properties, we’ll style the text that will represent the wattage and cost values.

Style section text area
04:51

Instead of adding extra, repetitive information within the HTML file, we’ll use CSS pseudo elements to add the currency information, as well as the duration values to the cost indicator.

Preview 03:41

Next, we’ll style the main form element in order to position the form elements within to a 3-column layout.

Styling the form area
02:53

We'll use CSS to control aspects for the form design, including setting font sizes and custom arrows for the select (dropdown) menu.

Styling the form text and elements
05:50

Using CSS media queries, we’ll make the design responsive by adjusting the layout for small screens.

Adjusting the Main area for small screens
04:31

To account for form elements on small screens, we’ll make additional adjustments which will help the experience on mobile devices.

Writing the Calculation Script
8 Lectures 32:46

We'll begin our AngularJS application by defining an app variable and a controller in our JavaScript file. Then, we’ll assign the app and controller to elements within the HTML file.

Preview 05:57

By defining the lumens values in an array variable, we can use AngularJS to dynamically populate the select menu with those array values.

Setting up our select options
04:08

Now we'll define a series of variables, as well as default values for them. This will allow the calculator to have some default data when the page first loads.

Setting default input values
03:32

Next, we'll set up a variable for each bulb’s conversion value.

Set variables for conversion values
01:47

Creating a custom function within our AngularJS controller allows us to run a set of instructions based on page load, or user interaction with the calculator.

Creating a custom function in the controller
01:50

In order to calculate the wattage needed for the incandescent bulb to produce 600 lumens of light, we’ll multiply the lumens by the corresponding conversion rate.

Calculate wattage usage for incandescent bulbs
04:48

With our calculations for incandescent bulbs complete, we’ll duplicate the conversion statements, and switch the conversion rates for each of the remaining bulbs.

Calculate wattage usage for remaining bulbs
02:32

In order to calculate the cost, we’ll need to calculate the total number of hours per year the bulb will be used, then multiply that by the cost and wattage requirements.
