Mulch Calculator using jQuery

Mulch CalculatorI’ve been toying around with learning jQuery, lately. I went out and bought a book and started going through the exercises. jQuery is really a sub library of JavaScript and it’s a really popular way to add cool enhancements to a website.

According to Wikipedia:

jQuery is a cross-browser JavaScript library designed to simplify the client-side scripting of HTML. It was released in January 2006 at BarCamp NYC by John Resig. Used by over 31% of the 10,000 most visited websites, jQuery is the most popular JavaScript library in use today.

As with any language on the web (and spoken languages, too), you can do some cool stuff even without being completely fluent in it. Thought I haven’t been using jQuery very long, I’ve already completed two projects with it.

My latest project was to build a mulch calculator that would help the user to know how many yards of mulch they will need to fill a certain spot. The user needs to know 3 things:

  1. Length in Feet
  2. Width in Feet
  3. Thickness in Inches

Here’s the formula for calculating what you need:
(Length * Width * (Thickness / 12)) / 27

You’ll notice that there is a semi-complex order of operations going on here

  • First we have to convert the inches to be on the same playing field as the feet by dividing by 12.
  • Then we have multiply length, width and our converted thickness together.
  • And lastly, all of that is divided by 27.

After much trial error, here is the JSFiddle.
