Okay, well I have an Array of "bad words" that cannot post, so I need a code that scans through the the textarea to find any "bad words" and if it does it runs a function... Thanks...

how about this (there might be an easier way to "implode" the array, but i'm not very familiar with the javascript array functions):

function implode ( my_array ) {
  var to_be_returned = "";
  for ( var i=0; i<my_array.length; i++ ) {
    to_be_returned = my_array[i] + "|";
  }
  // there's a | too much at the end, so we need to remove it first:
  return to_be_returned.substring ( 0, to_be_returned.length - 1 );
}
 
function checkForInvalidWords ( obj ) {
  var result = obj.value.search ( "(" + implode (array_of_bad_words) + ")");
  if ( result == null ) {
    // valid words
  } else {
    // invalid words found
  }
} 

and the html:

HTML Code:

<textarea name="text" onblur="checkForInvalidWords(this)"></textarea>

The "result" variable will hold an array with all matched invalid words, so you can simply use the string.replace method to replace them with a different word or censure them

It's join(), in JavaScript.

On a sidenote, I often use a similar method to check if a string exists in an array of strings by making the stringArray a Regular Expression.
It's especially useful if the array changes dynamically between tests.
^ means the beginning of the testString, $ means the end, and | means "or".
The "i" means it ignores upper/lower case.

var theStrings = ['String A','String B','String C'];
function exists(testString)
{
  return new RegExp("^"+theStrings.join("$|^")+"$","i").test(testString);
  // Evaluates to the same as /^String A$|^String B$|^String C$/i.test(testString)
}
