#! code

I was sent an email the other day that contained some text were the start and end letter of each word were left alone, but the middle of each word was randomized. The weird part was that the text was still readable, which is due to the way in which the brain processes words.

Use the following function to filter out words from user input. It works by having a pre-set array of words that are to be excluded, this array is then looped through and each item is used to replace any instances of that word within the text. The regular expression uses the \b character class, which stands for any word boundary. This way you don't get the middle of words being filtered out when they are not meant to be.

Counting the number of words in a block of text can be tricky. Users tend to create sections of white space that can throw out most scripts that don't take this into consideration.

I have created a tool for #! code that looks at a textarea of a form, and prints the number of words into an input box in the same form. The textarea calls a function called textCounter() every time a key is pressed.
