Explosive Runes

Random Generator

Source Code

The following source code provides a simple yet flexible JavaScript random text generator, and some example data. Both are released to the public domain.

Using the Generator

First, you'll need to create a JavaScript data file. This file defines tables as named elements of the gen_data object (which is declared in generator.js). Typically, the first or main table in the file contains text patterns, which may include phrases or words from other tables indicated by {name}. Note that table names can only contain the letters a-z, digits 0-9, and the underscore. A table may be defined as a simple array list, or as a indexed object (see the warrior_data.js file for examples of both).

Then, include both the generator.js file and your data file in your HTML page. A clever person might note that you could easily create and include more than one data file here.

<script type="text/javascript" src="generator.js"></script>
<script type="text/javascript" src="warrior_data.js"></script>

The generate_text() function accepts a single argument, the name of your main table, and returns a text string. You can simply write this text string to the HTML page...

<script type="text/javascript">
  document.write(generate_text('warrior'));
</script>

Or assign it to a variable in your own JavaScript code. You may also be interested in the generate_list() function, which accepts the name of a table and a number, and returns an array of generated text strings.
