JavaScript: Word Filter

OK, here is my code. I need this to check the array against a textarea as well. how can this be done?

function check() {
var bad = new Array('word1','word2','word3');
// INPUT BOXES
var text=document.getElementsByTagName('INPUT');
for (var i=0;i<text.length;i++) {
if ((text[i].type=='text')&&(text[i].value!=''))
for (var j=0; j<bad.length;j++) {
if (text[i].value.toLowerCase()==bad[j].toLowerCase()) {
alert('\"'+bad[j]+'\"'+' not allowed!');
return false;
}
}
}
return true;
}

It doesnt seem to want to work, it ends up breaking the input box
