Check input of a text box

[caveman]

Hiya,

Is there anyway you can check the input of a text box? For example if you had a textbox which submits articles to the site and you want to make sure you dont get any rude language... Is there such a script?

I assume that you mean a textarea. You can use regular expressions to parse the text and search for rude words.

Use the RegExp object (regular expressions), e.g. the regular expression

(rude|naughty)

would match either "rude" or "naughty" in the text.
