Hi.

Right, basically I'm trying to write a swear checker function. The code is this:

The swear checker itself seems to work - it chucks up an alert if any of the words are found - but what it doesn't do is stop the form from doing it's action. So even if the alert comes up, the 'return false;' part of it never seems to get through and I really don't know why.
As well as that in the alert, if there's more than one word, there's always a comma before every word after the first and I cannot ascertain as to why.

Any ideas?

Cheers.

Here's one thing I noticed which I thought was pretty obvious, but it may not be the only problem with the script:

Change:

to:

First of all, I know absolutely SFA javascript

Regarding your first problem, I would hazard a guess it's to do with the value being returned. If the line:



Were hard coded:



..does that definetly do what you want it to do (presumably stop the form from submitting)? If it does, I would look at the actual value being returned your swear_checker() function - try outputting it in a popup box or something.


Regarding your second problem, I would guess it's just what you get when you output an array - you get each value printed, with a comma in between. If you want more control, make a loop to cycle through all the elements in the array, which will give you as much control as you want over how it's written to screen.
