Typing Test Systep

Introduction

This is a somewhat advanced JavaScript Typing Test system that will allow you to place a table and a few blocks of code on your website (perhaps on a job application system as we did) and get a detailed statistical information on your user's typing ability, including:

  • Words Per Minute (WPM)
  • Accuracy Percentage Rating
  • Total Words Typed
  • Good Words / Bad Words Typed (Errors)
  • Time Taken to Complete
  • More as needed

To see the system in use, visit http://www.itsllc.us/TypingTest_1.asp; you may also download a lower quality version above, or follow along with the code below.

Background

There isn't much of a background to this code except for the fact that it uses JavaScript as a base to execute -- and yes, this is completely client side scripted. You could do the same thing in a server side scripting language or environment such as ASP; however, it would more than likely be less effective.

Using the code

To implement the code below, simply write (or copy and paste -- which is quicker, yeah) the code below into the <HEAD> section of your document -- or anywhere else as you wish, if you are using an include.

Shown below is the JavaScript code required to make the system work. It's fairly straightforward, and very high on the "commented" side -- so you shouldn't have any issues understanding; but if you do, don't hesitate to leave a comment or contact me.

<SCRIPT LANGUAGE="JavaScript">

// True = The test has already started

// - If you update the array, be sure to update the intToTestCnt
//   with the number of ACTIVE testing strings

When you have the JavaScript inserted into the page, all you need then is the code for the components (which was done fairly quickly without the use of CSS -- as it is a little messy, you get the point and can re-write or organize as you wish).
